Describe TWO structural suitability of the villi for absorption
Answer:
Explanation:
Villi are filled with blood capillaries, and the blood constantly moving in them means that a steep concentration gradient is maintained. This increases the amount of dissolved, digested food that can be absorbed into the bloodstream from the small intestine.
Every square inch of the intestinal mucosa is comprised of around 20,000 villi, and the surface cells of the mucosa also have projections of their cell membranes called microvilli, all of which contribute to the increased surface area. This enables a great area to be available for the absorption of nutrients.

Jasmine has high blood pressure and an increased glomerular filtration rate (GFR). How does the tubuloglomerular feedback mechanism restore normal pressure in her glomerulus
The tubuloglomerular feedback mechanism will restore normal pressure in her glomerulus by lowering glomerular filtrate rate in order to remove excess salts.
What is the glomerular filtration rate (GFR)?The glomerular filtration rate (GFR) is the amoubtbof blood that passes through the glomerulus for filtration per minute.
A glomerular filtration rate (GFR) of 60 or higher is normal
Since Jasmine has high blood pressure and an increased glomerular filtration rate (GFR), the tubuloglomerular feedback mechanism will restore normal pressure in her glomerulus by lowering glomerular filtrate rate in order to remove excess salts.

Drug-resistant populations of microbes arise when: Group of answer choices exposure to drugs causes mutations that produce resistance. synergy between medications occurs.
exposure to drugs causes mutations which produce drug-resistant populations of microbes.
What is the effect of using same type of drug?Drug-resistant populations of microbes arise when the exposure to drugs causes mutations because this exposure produce resistance which leads to mutation in the organism. Due to this mutation, the drugs did not work on the organism anymore.
So we can conclude that exposure to drugs causes mutations which produce drug-resistant populations of microbes.

If a female with blood type oo has children with a male with blood type ab, what are the possible blood types of their children?.
Answer:
50% with blood type A and 50% with blood type B
Explanation:
You can draw a punnet square and find that the possible combinations are AO, AO, BO, and BO. The presence of antigens on the blood cells make them type A,B or O. If antigens are put on O they can be made into a new blood type. For example if A mixes with O the fused blood will be of type A.
I hope this explaination helps you!
Only the O allele can be passed on to a child by a mother who has blood type O. A parent with blood group AB could give his kid or daughter either an A or a B gene. Blood type B or blood type A (O from the mother and A from the father) could be the blood type of the children of this couple (O from mother and B from father).
What is Blood group?According to the presence or absence of antibodies or hereditary antigenic compounds just on surface of red blood cells, blood is classified according to its type. Depending on the blood group system, these antigens could be proteins, carbohydrates, glycoproteins, or glycolipids.
The ABO system distinguishes 4 major blood types:
Blood group O - has no antigens, however both anti-A and anti-B antibodies in the plasma Blood group AB - has both A and B antigens, but no antibodies Blood group A - has A antigens just on red blood cells with anti-B antibodies in the plasma Blood group B - has B antigens with anti-A antibodies in the plasma.Thus, only the O allele can be passed on to a child by a mother who has blood type O. A parent with blood group AB could give his kid or daughter either an A or a B gene. Blood type B or blood type A (O from the mother and A from the father) could be the blood type of the children of this couple (O from mother and B from father).

What are nucleotides?The genetic material DNA is made up of nucleotides. Nucleotides are the base pair that comprise the genetic material. There are two types of bases present, therefore, purine and pyrimidine. These bases are further divided, purine bases are adenine and guanine whereas pyrimidine bases are cytosine, thymine, and uracil.
DNA and RNA both are made up of nucleotides. The only difference between DNA and RNA nucleotide base pairs is that adenine pairs with uracil instead of thymine. Nucleotide is made up of sugar, nitrogenous base, and phosphate. When a nucleoside attaches to the phosphate is called a nucleotide.ATP is a nucleotide as well energy molecule.

In the year 2000, specimens of caulerpa taxifolia,a green alga used in tropical aquariums, were found off the coast of california. Native to the indian ocean, c. Taxifolia is known for aggressive growth and an ability to compete with sea grasses. It is currently on an international list of invasive species. Which of the following best predicts the consequences of the introduction of c. Taxifolia to the california coast?.
The consequences of the introduction of c. Taxifolia to the coast of California is the disappearance of other algae species where C. taxifolia colonizes.
What are the impacts of C. taxifolia?This alga causes a marked decrease in biodiversity in the environments colonized by it. It was observed, in 1991, that it covered the beds of algae of Cymodocea nodosa and especially of Posidonia. Initially, the Posidonia seaweed bank seems to react positively to contact with the seaweed, increasing its production. Later, after being completely invaded, it shows signs of "stress" (leaf fall...) leading to a setback and then the total disappearance of the algae bank as well as the algae that grew together with the posidonias.
Whit this information, we can conclude that the consequences of the introduction of c. Taxifolia to the coast of California is the disappearance of other algae species where C. taxifolia colonizes.
