Answer:
cremaster muscle
Explanation:
The cremaster muscle covers the testes and the spermatic cord.
The muscle raises and lowers the testes in order to regulate the temperature of the scrotum
When temperature drops, the cremaster muscle pulls the testes closer to the body.
• The muscle found within the body of male and covers the testis is the cremaster muscle.
• The muscle moves the testis, encouraging motile and healthy sperm.
• The cremaster muscle raises and lowers the testis in order to control its temperature. When a man moves into an environment with a colder temperature, the muscle makes the testis to move closer to the body.
• The muscle also functions at the time of flight or fight scenarios, when the man runs to enters a fight, the muscle pulls the testis closer to the body and safeguard it.
Thus, the cremaster muscle pulls the testis closer to the body when temperature drops.

how do scientists decide when to change or modify their understanding of a particular topic?
Answer:
they carry out experiments to understand it
Explanation:
Scientists raise hypotheses which are tested by experiments made under controlled conditions in order to explain a particular topic. When a hypothesis is confirmed by the experimental data, the evidence obtained from this experiment provides the basis to increase the scientific knowledge about a particular issue. In consequence, experimentation can be considered as a critical step in the scientific method and research aims to advance knowledge of a particular phenomenon by confirming a hypothesis, which must be testable (i.e. verifiable as a result of further experimentations).
Which of the following is true of an ecosystem?
A.There will be more herbivores than any other
organism in an ecosystem.
B.There will be more carnivores than any other
organism in an ecosystem.
C.There will be more carnivores than herbivores in an
ecosystem.
D.There will be more producers than herbivores in an
ecosystem
Answer:
D.There will be more producers than herbivores in an ecosystem
Explanation:
In an ecosystem, organisms feed on one another in order to obtain energy needed for their life processes. The series of chain by which organisms derive energy by feeding on one another is called FOOD CHAIN. A good chain always start with a PRODUCER (an organism capable of synthesizing its own food via photosynthesis). Organisms called HERBIVORES feed directly on the producers, and subsequently CARNIVORES feed on the herbivores.
According to the pyramid of numbers, which shows a graphical display of the number of organisms occupying each trophic level, the producers which are at the bottom of the pyramid are always more in number than any other organism in the food chain. It takes fewer herbivores to consume a large number of producers.

What is the function of enzymes in plants
Plz help ASAP
Thank you
Answer:
D. Produce simple glucose from sugars
Explanation:
Enzymes are regarded as biological catalysts that helps bring about biochemical reactions in living systems. They perform day-to-day activities in living cells including anabolism (build up molecules), catabolism (break down molecules) etc.
Amylase is an important group of enzymes found in plants. They catalyze reactions involving the break down of large carbohydrate molecules into simpler ones. Large polysaccharides like starch in plants are broken down to simple sugars like glucose with the help of catalytic enzymes called AMYLASES. The glucose is used to supply energy to the plant cells.
Which structure is highlighted? Which structure is highlighted? hepatic portal vein quadrate lobe inferior vena cava gallbladder
Answer: (Note: You will find the image as an attached file)
Gallbladder.
Explanation:
The gallbladder is an organ located under the liver that intervenes in food assimilation by the organism. Its main function is to store bile - a liquid produced by the liver to dissolve fats -. The liver produces bile and it reaches the gallbladder through the hepatic and cystic ducts, and it is stored in the gallbladder until it is needed. Whenever the stomach or intestine are digesting food, the gallbladder release the bile which flows through the cystic duct and the bile duct to the thin intestine. In fact, the secretion of bile by this organ is stimulated by food ingestion, especially by the ingestion of meat or fats.
Reflect and Respond As you read through the research in Case Study: Sea Turtles, keep in mind the three basic steps of addressing challenges to ecological well-being. Answer these three questions as you review the information on the Everglades. Identify the problem(s) at hand. Determine the cause of the problem(s). Recommend solutions to the problem(s). A sample answer might include the following: Identify the problem(s) at hand. There are five species of sea turtles that live in the mid-Atlantic oceans of the United States. All five are on the Threatened or Endangered Species lists. Will increased use of offshore wind power technologies impact sea turtles? Determine the cause of the problem. Sea turtles face a variety of environmental dangers. Many are killed by accidentally getting caught in fishing nets. Many boats and ships run over the sea turtles, causing bodily damage or death to the turtles. Development of the coastlines impacts the nesting habitat of the turtles. Sea turtle nests are destroyed or damaged by predators or humans. Recommend solutions to the problem. Select locations for wind power technology and equipment that won’t impact sea turtle habitats.
Answer:
The nesting zone of ocean turtles could be saved and ensured with the assistance of commitment of neighborhood individuals , maintaining a strategic distance from of sea shore fires during settling season. A lot of advancement of sea shore territory leaves less ground for the turtles to cover for the settling processes,so less improvement of the sea shore.
There ought to be insignificant lighting close to the nesting zones as angled turtles are pulled in to light and they may wind up moving towards the city as opposed to the water. Local people could shield the hatching eggs from being originated before by other wild creatures and feathered creatures by labeling them and keeping a nearby eye.
Beach area cleanup ought to be basic as the debris are the significant reason forever danger to the turtles and all other marine creatures.
During incubating and hatching period the coast line ought to be shut and forbidden to human obstruction. Additionally sheltered return of the ocean turtles subsequent to laying eggs and furthermore in the wake of bring forth of the eggs could be guaranteed by local people or the individual from any association working for the protected watchman of the turtles.
Sun oriented force age and wind power age advances are in any case have an extremely lesser effect on turtle propensities. Be that as it may, as wind plants being set up in seaside regions it's being industrialized in this manner presents issue for turtles. Desert regions are a lot of appropriate too for age of both of these sort of intensity age methods along these lines sea shores remain sheltered and open for turtles to lay eggs.

What are physical properties? Give some examples.
Answer:
A physical property is any property that is measurable, whose value describes a state of a physical system. The changes in the physical properties of a system can be used to describe its changes between momentary states. Physical properties are often referred to as observables. They are not modal properties. Quantifiable physical property is called physical quantity.
Examples:
color (intensive)
density (intensive)
volume (extensive)
mass (extensive)
boiling point (intensive): the temperature at which a substance boils
melting point (intensive): the temperature at which a substance melts
Answer:
A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity.

Insectivorous birds are more likely to eat medium sized insects because the exoskeleton of large insects is too hard to break, and small insects are too hard to find.
a. True
b. False
Answer:
Option A: True
Explanation:
Insectivorous birds such as bluebirds, dippers and flycatchers prefer to eat medium-sized insects. This is because like most birds, they love easy and satisfying meals. To the birds, a medium-sized insect is a good compromise because it is quite easy to chew and digest and at the same time, easy to find.
As a result, most insectivorous birds prefer to get their daily ration of proteins from the medium-sized birds.
a. Add to the formula in Interactive Question 3.5 to
show how increasing (CO2) dissolving in water leads
to a lower pH.
b. Use this formula to explain how a lower pH would
affect the [CO32-) in the ocean.
HCO3 SCO32- + H+
c. Assuming a fairly constant (Ca2+] in the ocean, how
would a change in (CO32-) affect the calcification
rate--the production of calcium carbonate
(CaCO3)-by the coral in a reef ecosystem?
Answers and Explanation:
a.)
Lower pH of a substance is indicative of increased acidity. By dissolving carbon dioxide to release [tex]CO_{3} ^{2-}[/tex] which easily reacts with water to form carbonic acid, thereby increasing water acidity.
b.)
The increased acidity of the ocean makes the water naturally corrosive and soft which implies reduced carbonate levels in the ocean.
c.)
Calcification occurs through formation of calcium carbonate by reaction of calcium with carbon dioxide, or even more easily Ca2+ and [tex]CO_{3} ^{2-}[/tex]. This implies that increased calcium levels in the ocean increases rate of calcification and reduced [tex]CO_{3} ^{2-}[/tex] ions.

Explanation:
After hurricane Irma, and partially trigger by news distributed by social media during that period, people in Ecuador (particularly in coastal places) have started to worry that changes in climate will translate into having tropical cyclones of similar magnitude hitting their country. After all, unusual patterns of rainfall, increase temperature that is melting glaciers in the Andes, etc., are relatively new climate-related events easily perceivable by people. As a climate expert, please explain to Ecuadorians briefly: 1)how tropical cyclones are formed and where they occur globally mentioning key factors for their formation and for them to gain strength; 2) using the previous information, discuss whether or not they have reason to worry about a tropical cyclone of high magnitude hitting Ecuador as a result of changes in climate.
Answer:
1. Cyclones are one of nature’s responses in which winds move in a circular motion when hot and cold air currents meet under low atmospheric pressure.
Tropical cyclone formation takes place when sea-surface temperature rises and meet with vertical wind shear and high relative humidity leads to a winds swirl around the area of low atmospheric pressure.
2. Yes, people have reason to worry about a tropical cyclone of high magnitude hitting Ecuador as a result of changes in climate because due to climate change, sea-surface temperature is rising continuously which can lead to cyclone of high magnitude and come with more disaster.
Do any cells in the population express Glut4 on their surface? Is this expression dependent on the presence of insulin receptor? Is this expression dependent on the presence of insulin? Explain.
Answer:
Glut4 is only expressed in insulin-sensitive skeletal an heart muscles and fat tissues.
Explanation:
Glucose transporters represent a group of integral membrane proteins that allow the transport of glucose molecules across the plasma membrane by the mechanism of facilitated diffusion (i.e., without direct coupling to ATP hydrolysis). In humans, the Glucose Transporter type 4 (GLUT-4) is a glucose transporter encoded by the SLC2A4 gene. This protein plays a critical role in regulating glucose homeostasis by enabling to increase the transport of glucose in response to elevated blood insulin levels in adipocytes, skeletal and cardiac muscle tissues.

In tomatoes, tall (D) is dominant over dwarf (d) and smooth fruit (P) is dominant over pubescent fruit (p), which is covered with fine hairs. A farmer has two tall and smooth tomato plants, which we will call plant A and plant B. The farmer crosses plants A and B with the same dwarf and pubescent plant and obtains the following numbers of progeny: Progeny of: Plant A Plant BDd Pp 122 2 Dd pp 6 82 dd Pp 4 82 dd pp 124 4 a.What are the genotypes of plant A and B
Answer:
The correct answer would be - Dd Pp.
Explanation:
As it is given that tall D is dominant over dwarf d and smooth plant Pis dominant over pubescent p so the the genotype of dominant trait that is tall and smooth tomato plants would be DDPP . similarly the recessive trait that is dwarf and pubescent plant would be ddpp
Thus, the cross between these would be -
DD PP x ddpp
And gametes would be - DP,DP, dp, and dp.
So, all the 16 offspring would have Phenotype would be heterozygous tall and smooth and DdPp genotype .
Thus, the correct answer would be - Dd Pp.
Explain briefly what the El Niño Northern Oscillation (ENSO) is and how it would affect the following locations: Piura, Peru; Port Moresby, Papua New Guinea; Gainesville, FL, USA. Be detailed and scientific – give reasons and explain your answer for each location.
Answer and Explanation:
The ENSO phenomenon is the result of a complex system of climatic oscillations between the ocean and the atmosphere. It is considered to be dominant in the global climate system. This phenomenon is associated with important perturbations in the normal pluvial regimens in the tropics, resulting in dry seasons in areas where usually rains, and rainy seasons in areas that are usually desertic.
Under normal conditions, warm water and air masses move westward, which makes it possible for cold water to ascend in a process known as upwelling. This upwelling occurs in South America´s coasts, providing nutrients from the bottom to the animals, especially fishes -which favors fisheries activities-. Humidity goes straight to the west precipitating in Indochina and North Australia, among other places.
Under El Niño conditions, a tropical stream, which is normally small, acquires strength while the opposite streams debilitate. This avoids warm water to go eastward, remaining in South America´s coasts, which produces unusual precipitations in areas such as Chile´s coasts -followed by floral bloom in Atacama desert-, and fewer precipitations in Eastsouth Asia and North Australia. Upwelling does not occur on the coasts of South America, so there is a fishery crisis because nutrients from the bottom do no ascend and fish populations remain equal or smaller. In areas such as Piura, Perú, during el Niño events, temperatures use to rise in the coastal areas and precipitation also increase. Nueva Guinea, on the other hand, seems to one of the most affected areas in Eastsouth Asia under the influence of El Niño event. Rainfall during ENSO drops below the average, affecting crops and livestock.
ENSO also provokes changes in general extratropical circulation contributing to some anomalous situation in the northern hemisphere weather during winter, including severe precipitations and cooler temperatures in the southeast USA, north of Mexico, Gulf of Mexico, Strait of Florida and western Cuba.

Which of the following statements are true? Check all that apply. Atoms of the same element can have different numbers of protons. Atoms of the same element have similar chemical behavior. Atoms of the same element can have different numbers of electrons. Atoms of the same element can have different numbers of neutrons.
Answer: Atoms of the same element have similar chemical behavior
Atoms of the same element can have different numbers of neutrons.
Explanation:
Atoms of the same element have similar chemical behavior as it is decided by the number of electrons which remains same for same elements.
Mass number is defined as the sum of number of protons and neutrons that are present in an atom. Atomic number is defined as the number of protons or number of electrons that are present in an atom.
Isotopes are elements which have same atomic number but different mass number. That means they are same elements with same number of protons and electrons but different number of neutrons. Example: [tex]_1^1\textrm{H}[/tex] and [tex]_1^2\textrm{H}[/tex]

How can a uniporter, GLUT2, be sufficient for entry of glucose from intestinal epithelial cells into the bloodstream?
Answer:
This is because we know the amount of Glucose inside the intestinal epithelial cell is higher than in the bloodstream so a uniport in the basolateral surface of the intestinal epithelial cell canbbe used to move glucose into the blood stream and it is the two-Na+/one-glucose symporter placed in the apical surface, acting as secondary active transport that generates the high amount of glucose inside the epithelial cell
Hi Class, So, why does differentiation occur in an organization? Distinguish between vertical and horizontal differentiation.
Answer:
Differentiation occurs because as organizations grow and become more complex, they establish a division of work. Vertical differentiation is a ranking of power with reporting relationships established to connect organizational roles and sub-units. Where horizontal differentiation are group roles according to task responsibilities, establishes division of power, and forms sub-units.
Describe the arrangement and general function of simple squamous epithelium.
Answer:
When group of tissues are formed from a cell layer of squamous cell,then the epithelium formed is said to be simple squamous epithelium.These cells are tightly packed together,to form the lining of the cell surface.Thus they are in directs contact with the basement membrane underlying the cell structure. Therefore,they act as selectively membrane structure for osmosis,diffusion,This explain their presence in the alveolar and kidney,where filtration takes place
In additions ,due to their one cell layer thickness,they form the lining of fragile of delicate body cavities. e.g the alveolar in the lungs, lymphatic vessels,and inner lining of the wall of the heart.
