The ABO classification is the most important and relevant for blood compatibility. A small number of antigens and antibodies are responsible for the ABO blood types. The specific combination of these components determines an individual's type in most case
Explanation:
The absorptive effectiveness of the small intestine is enhanced by increasing the surface area of the mucosal lining. Which of the following accomplish this task?
a. the rugae and haustra
b. plicae circulares, villi, and microvilli
c. the vast array of digestive enzymes
d. Brunner's glands and Peyer Patches
Answer:
Option B
The plicae circulares, villi, and microvilli
Explanation:
The plicae circulares are the folds of mucous membrane on the inside of the small intestine. They are covered with tiny hair-like structures called the villi, and microvilli. The purpose of those folds is to increase the surface area for the absorption of food nutrients to take place in the small intestine before the food finally moves on to the large intestine for excretion.
The tiny hair-like projections (villi, and microvilli) further increase the surface area available for nutrient absorption by providing extra surfaces in which the nutrients can diffuse into the small intestine through.
This makes option B correct.
the most common source of osteomyelitis is an infection that migrates via the bloodstream. direct invasion from a fracture. surgical contamination. a joint prosthesis.
Answer:
The correct answer is ''an infection that migrates via the bloodstream.''
Explanation:
An infection is the invasion of pathogenic germs or microorganisms that reproduce and multiply in the body causing disease. Bones, like any other organ or tissue in the human body, can become infected. Osteomyelitis is a bone infection caused by bacteria, mainly Staphylococcus aureus, although in some cases it can also be caused by fungi. The infection can start in another part of the body and spread to the bone through the bloodstream. In this case, it usually occurs at the ends of the leg and arm bones in children and in the spinal column (vertebrae) in adults, especially the elderly.
Earth's Greatest Enemies?Climatologist James Lovelock(originator of theGaia_hypothesis ) once said that Earth's greatest enemies were cars, cows and chainsaws because of their contributions to destabilizing planetary climate.1. How do each of these things (cars, cows, andchainsaws) contribute to the destabilizing of Earth's atmosphere and climate? You must cite specificevidence from any Unit of the course to support your response. And...2. How are these three things connected to one another either by cause, effect or by solution. Consider all of the environmental concerns you have been learning about during the entire course and describe how these 3Cs as a group relate to one specific environmental issue (other than atmospheric destabilization).Reminder: Loss of land plants will not result in a reduction of atmospheric oxygen (because most of planetary photosynthesis and its resulting oxygen production is in the oceans).
Cars, cows and chainsaws are major polluters and their use must be regulated and limited, to reduce the emission of polluting gases into the atmosphere that can cause drastic climatic changes that harm the environment that we know intensely.
Although it is not widely publicized in the media and few people know about it, the chainsaw is a great villain of the earth's atmosphere, since its use releases large amounts of CO2 into the atmosphere, due to the burning of gasoline that these machines make to work. CO2, in addition to endangering the operator's life, is a gas that destroys the ozone layer and increases the effect of global warming. Not only does the chainsaw release this gas, but so do cars, which reinforces the need to use renewable fuels to be used in both cases.
Cows also release polluting gas, methane, which has a greater polluting potential than CO2. Methane is the result of the cow's digestive reactions, which release this gas into the atmosphere steadily. As herds of cows tend to be large, livestock becomes a major polluter, as herds result in a strong release of methane into the environment. This reinforces the need for increasingly stronger regulations for livestock, in addition to highlighting the importance of adopting alternative methods of feeding that reduce meat intake.
What is the least hydrophilic substance
Answer:
oil
Explanation:
Among the given ones, the least hydrophilic substance is oil. The correct option is C.
What is hydrophilic substance?The 'hydrophilicity' of a molecule or surface refers to how much or how little it draws water.
Sugar, salt, starch, and cellulose are a few of the most typical examples of hydrophilic compounds. Polar compounds are those that are hydrophilic.
In contrast, since oils are nonpolar, they are not drawn to the polarity of water molecules. Oils are in fact hydrophobic, or "fearful of water." Oil molecules are repelled by water molecules rather than attracted to them.
A molecule of oil has a non-polar structure. Its charge does not have a positive or negative end, but is evenly balanced.
Thus, the correct option is C.

Which of the following is a characteristic of all rocks?
A) They all have the same texture.
B) They all look alike.
C) They all have the same color.
D) They are all made of one or more mineral
answer:
Rocks are classified according to characteristics such as mineral and chemical composition, permeability, texture of the constituent particles, and particle size. These physical properties are the result of the processes that formed the rocks.
The characteristic that is present in all rocks is they are all made of one or more minerals. The correct option is D.
What are rocks?Rocks on the big stones are made up of an accumulation of small stones and San materials. They are made up of one or more minerals that join together.
There are different types of rocks that are differentiated by the process of their formation. The types of rocks are igneous rocks, sedimentary rocks, and metamorphic rocks.
Now, sedimentary rocks are formed by the deposit of minerals and other materials. Metamorphic rocks are formed when the pressure and heat from the Earth turned igneous rocks into other rocks and that is called metamorphic rock.
Igneous rocks are formed by the cooling down of hot Lava and Magma that comes out of volcanoes.
Thus, the correct option is D) They are all made of one or more minerals.

How do tiny atoms bond together to form bigger substances , and how are these substances important for life ?
Answer:
The detailed answer to this question is found in the explanation section.
Explanation:
Life is generally made up of matter, which is referred to as anything that has mass and occupies space. Matter is composed of elements such as carbon, hydrogen, oxygen etc, which in turn constitutes the smallest indivisible unit of an element called ATOMS.
Atoms are chemically bonded together to make up the elements in molecules and compounds. These compounds and substances are contained in the basic unit of life called CELLS, which play a pivotal part in the sustenance of life. For example, the enzymes and hormones that bring about physiological responses in our body are made up of protein molecules. These protein molecules are similarly composed of chemical elements such as carbon, oxygen, hydrogen, nitrogen etc, whose building blocks are atoms.
In a nutshell, all LIFE characteristics are made up of matter which possess atomic particles that are chemically bonded together to form substances that hold life together.

Answer:
Reduced extracellular fluids within the kidney, reduced blood pressure.
Explanation:
The loop of henle, which are located within the nephrons in the kidney, have a task of acquiring the water and NaCl from the blood and keeping enough of it in the body so that the homeostasis is maintained.
The result of giving Lasix that reduces the amount of NaCl reabsorption would first of all be "reduced extracellular fluids within the kidney" and it would also change the pH level of the blood and drop blood pressure levels.

Sodium and potassium ion channels have several negatively charged residues at the entry to the channel. Identify the bases on which K channels specifically select for K ions, in other words, why do K channels not enable Na ions to cross the membrane
Answer:
Mechanism in attachment.
Explanation:
K⁺ channels have narrow pores, which prevents the passage of larger ions. However, since Na⁺ has an ionic radius smaller than K⁺, this does not explain the selective permeability of these channels towards K⁺.
In this case, the channel pore has a narrow selective filter which is delimited by the backbone carbonyl oxygens (C=O). When a K⁺ ion enters in the selection filter it interacts with these oxygens, and the molecules of water bound to K⁺ are displaced, which allows the passage of the dehydrated ion K⁺ through the pore. However, a dehydrated Na⁺ is too small to interact with these carbonyl oxygens in the selective filter, which stays open. As a consequence, the Na⁺ ion remains bonded to the water molecules in a hydrated complex that is too big to pass through the channel.

Answer:
The correct answer is - 16 genetically different kinds of sperm could be produced by a Drosophila melanogaster male (XY).
Explanation:
There are four pairs of chromosome in Drosophila melanogaster. In this species homologous chromosomes pair and segregate but do not follow recombination or crossing over. Each chromosome has two alleles or copies so as we know there are four pairs of chromosomes, then total number of chromosome copies would be 8, then
number of different combinations = 2^n (n = number of homologous pairs
)
2^n
= 2^4
= 16
Thus, the correct answer would be : 16.

PLEASE HELP ME!!!! This figure shows two alleles for the beta-globin gene. The A allele is the most common allele. The S allele is responsible for Sickle Cell Disease. The R group glutamic acid is negatively charged, while the R group of valine is hydrophobic. What molecular change, ultimately resulting in the sickle cell phenotype, occurs when valine in substituted in place of glutamic acid at position 6 in the β subunit of hemoglobin?
Answer:
The correct answer is option B. The tertiary structure of the beta subunit changes, exposing a hydrophobic cleft which allows hemoglobin to form long chains in RBC.
Explanation:
As it is clearly mention as there is point mutation that leads to single nucleotide change which results in to valine instead of glutamate. Valine is hydrophobic in nature not like glutamate. Valine aggregate and makes a rigid structure of molecules.
Due to this rigid molecule of valine aggregates, RBCs form a crescent or sickle like shape due to the higher viscosity and low solubility of Mutated hemoglobin in deoxy condition. It leads to formation of polymer that blocks the vessels.
Thus, the correct answer is option B.

In a certain breed of plants, dark green is determined by the dominant gene 'G' and light green is determined by the recessive gene 'g'. The heterozygotes show 75% penetrance. If the parental cross GG x gg was made, how many of each of the expected phenotypes will be observed in a population of 400 F2 plants
Answer:
The answer is 300.
Explanation:
When we cross GG and gg, 100% of the offspring will be heterozygous. If the heterozygotes show 75% penetrance meaning that there is a 75% probability that the plant that has the G gene will actually show it in it's phenotype.
So that means that 75% of the offspring should have dark green color, which means that 300 plants will have the expected phenotype and 100 will not.
