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 a chemical reaction? A. breaking a glass pane B. freezing water C. digestion of food D. cutting down a tree E. evaporation of rubbing alcohol
Answer:
C. When we digest food there are tons of chemical reactions occurring in the process, they would have to break down the food which is a chemical reaction.
Answer:
C. digestion of food
Explanation:
in a chemical reaction the substance changes composition and the reaction is mostly irreversible.
option C: digestion of food is a chemical reaction which changes the composition of the food we eat. Enzymes and other substances react with the food and turn it into soluble substances which the body can easily use.
option A: breaking glass does not change the composition of the glass plane. Its a physical reaction
option B: freezing water changes the state of water but the composition is still the same, its a physical reaction as well.
option D: cutting a tree does not change the composition of the wood. This, too, is a physical reaction.
option E: when a liquid evaporates it changes into a gas, which is a change in the state of matter (just like water into ice), this also does not change the composition of alcohol.
Which of the choices below determines the direction of respiratory gas movement?
a. pulmonary ventilation
b. transport of respiratory gases
c. external respiration
d. pulmonary respiration
Answer:
a. pulmonary ventilation
Explanation:
Pulmonary ventilation: In biology, the term "pulmonary ventilation" is also referred as "breathing" and is described as a phenomenon of moving air out and into an individual's lungs. Generally, air enters the "respiratory system" via nasal cavity and mouth, and then it passes through the "pharynx" and then the "larynx" and lastly to the "trachea" that enters the "chest cavity" of an individual.
In the question above, the correct answer is option A.

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.

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

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.
Besides they also contain membrane proteins,which aids the control of substances across their walls of tight junctions.Thus ions, molecules passages is regulated
Explanation:
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.

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.
Eye color is and example of
a. Translation control
b. Gene expression
c. Transcriptional control
d. Gene regulation
Answer:
b. Gene expression
Explanation:
The eye color trait is controlled by polygenetic heritability. A group of genes is responsible for the trait manifestation, and they must be associated to transmit the characteristic.
Eye color in a person is produced by pigments in the iris´ cells called melanocytes. At least two or more genes control melanin synthesis in the iris. Melanosomes are cellular structures produced by melanocytes, where melanin is produced and stored. Different genes control the eye color by its expression. We can name two of them as examples. There is a gene called OCA2 that codifies for the P protein synthesis. This protein plays an important role in the amount of melanin produced. The less P protein, the less melanin the cell will produce, which leads to blue eyes. Another gene called HERC2 contains a region known as intron 86 that controls the OCA2 gene, by allowing or inhibiting its expression.

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:

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.

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.
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]

-Look at the two fatty acids below.
Saturated fatty acid Unsaturated fatty acid
-Linoleic acid
What factor determines how much linoleic acid can twist and
bend its shape?
I
Answer:
The correct answer would be : carbon = carbon (double bonds between carbons)
Explanation:
Linoleic acids is a non polar polymer of unsaturated fatty acid (omega 6) made up of a polymer of 18 carbon chain. This unsaturated fatty acid have single bond in its structure but there few double bonds (already highlighted in question image).
These double bonds are makes twists or bend in the chains of fatty acid. These bends known as kinks formed by double bonds. Number of kinks increase the twist and bend in the fatty acid molecule.
Thus, the correct answer would be : carbon = carbon (double bonds between carbons)

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.

Convert 0.37 kilograms to grams. ____ grams
Answer:
370
Explanation:
I took you test
According to unit conversion, 0.37 kilograms is equal to 370 grams.
Unit conversion is defined as a multi-step process which involves multiplication or a division operation by a numerical factor.The process of unit conversion requires selection of appropriate number of significant figures and the rounding off procedure.
It involves a conversion factor which is an expression for expressing the relationship between the two units.A conversion ratio always has value which equals to one which indicates that numerator and denominator have values which are expressed in different units.
As [tex]1[/tex] kg[tex]=1000[/tex] g,thus to convert [tex]0.37[/tex] kg to g the value needs to be multiplied by [tex]1000[/tex] giving ,
[tex]0.37[/tex]×[tex]1000[/tex]=[tex]370[/tex] g.
Thus, 0.37 kilograms is equal to 370 grams.

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.

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.
