Answer:
Vasa recta.
Explanation:
Vasa recta are a group of capillaries, branching from the peritubular capillaries and moves parallel with the loop of Henle. Vasa recta is responsible for the supply of blood to renal medulla in order to purify the blood from the waste materials such as salts, excess water and nitrogenous waste etc. Due to its movement with the loop of Henle, it slows down the blood flow which helps in the re-absorption of water.

Which statement explains how a DNA mutation causes sickle-cell anemia? (point)
The DNA mutation increases the number of amino acids in hemoglobin, which causes a change in the shape of red blood cells.
The DNA mutation causes a change in the amino acid sequence for hemoglobin, which causes a change in the shape of red blood cells.
The DNA mutation decreases the number of amino acids in hemoglobin, which causes a change in the shape of red blood cells.
O The DNA mutation prevents formation of hemoglobin, the absence of wirich causes a change in the shape of red blood cells.
Answer:
The DNA mutation causes a change in the amino acid sequence for hemoglobin, which causes a change in the shape of red blood cells.
Explanation:
Sickle cell anemia is one of a group of disorders known as sickle cell disease. Sickle cell anemia is an inherited red blood cell disorder in which there aren't enough healthy red blood cells to carry oxygen throughout your body.
Normally, the flexible, round red blood cells move easily through blood vessels. In sickle cell anemia, the red blood are shaped like sickles or crescent moons. These rigid, sticky cells can get stuck in small blood vessels, which can slow or block blood flow and oxygen to parts of the body.
Sickle cell anemia is caused by a mutation in the gene that tells your body to make the iron-rich compound that makes blood red and enables red blood cells to carry oxygen from your lungs throughout your body (hemoglobin). In sickle cell anemia, the abnormal hemoglobin causes red blood cells to become rigid, sticky and misshapen.
The sickle cell mutation reflects a single change in the amino acid building blocks of the oxygen-transport protein, hemoglobin. This protein, which is the component that gives red cells their color, has two subunits. The alpha subunit is normal in people with sickle cell disease. The beta subunit has the amino acid valine at position 6 instead of the glutamic acid that is normally present. The alteration is the basis of all the problems that occur in people with sickle cell disease.
The DNA mutation causes a change in the amino acid sequence for hemoglobin, which causes a change in the shape of red blood cells.
What is mutation?A mutation is an alteration in the nucleic acid sequence of the genome of an organism, virus, or extrachromosomal DNA. Viral genomes contain either DNA or RNA.
Moreover, a mutation is a change in the DNA sequence of an organism. Mutations can result from errors in DNA replication during cell division, exposure to mutagens or a viral infection.
Therefore, when a gene mutation occurs, the nucleotides are in the wrong order which means the coded instructions are wrong and faulty proteins are made or control switches are changed. The body can't function as it should. Mutations can be inherited from one or both parents.

a. scabies, Pediculosis humanus
b. fever blisters, HSV-1
c. impetigo, Staphylococcus aureus
d. German measles, Rubella
e. shingles, varicella-zoster virus
Answer: shingles, varicella-zoster virus
Explanation:
It should be noted that shingles usually occur with old people and it causes a painful rash when the chicken pox virus is reactivated in the body.
Since the man is old and has painful fluid-filled vesicles that have begun crusting over in a wide band across the left side of his lumbar area and also has a history of chickenpox, it's very likely it is shingles.
Genes, Chromosomes, and DNA Quick Check
If one half of a DNA molecule has 8 thymine bases, what else is also true about the DNA molecule? ( point)
There will be 16 total bases.
There will be 32 total bases.
There will be 8 adenine bases.
There will be 8 cytosine bases.
Answer:
There will be 8 adenine bases.
Explanation:
There are total of 4 nitrogenous bases present in a DNA that includes Adenine, Guanine, Thymine, and Cytosine. These nitrogenous bases form complementary base pair in which, adenine form two hydrogen bonds with thymine and cytosine form three hydrogen bond with guanine.
So, if there are 8 thymine bases in a DNA (irrespective of half or full) then there will be 8 adenine bases, forming two hydrogen bond with each other.
Hence, the correct answer is "There will be 8 adenine bases."

Cloning to produce embryonic stem cells is called A) regenerative cloning. B) transplantational cloning. C) reproductive cloning. D) therapeutic cloning. E) dedifferentiation.
Answer:
D
Explanation:
The correct option would be therapeutic cloning.
First and foremost, cloning refers to the process of producing genetically and phenotypically similar organisms or cells from a single organism/cell, be it naturally or artificially. The genotypically and phenotypically similar copies of the original organism are called clones.
Artificial clonings are of different types, namely:
Reproductive cloningGene cloningTherapeutic cloningReproductive cloning has to do with producing genetically identical organisms from a particular organism while gene cloning involves producing exact copies of a gene or segments of DNA. Therapeutic cloning, however, involves the production of embryonic stem cells in order to create tissues that would replace similar but damaged or worn-out tissues in living organisms.

Have you ever noticed that aside from zoos, you don't see kangaroos, wombats, and koala bears outside of Australia? This is because there is a trench that is a "biogeographical transition zone between Asian and Australian flora and fauna". What is the name of that trench?
Answer:
Wallace Line
Explanation:
Wallace Line is a boundary line which is a transitional zone between Asia and Australia. This boundary drawn by the British naturalist Alfred Russel Wallace in 1859. This boundary restricts the transferring organisms such as flora and fauna from Australia to Asia. So that's why kangaroos, wombats, and koala bears are only present in Australia not in the continent of Asia.

Answer:
The correct answer is intragenic suppressor mutation.
Explanation:
A suppressor mutation partially or completely converses the effects of a different mutation. A suppressor mutation is of two kinds, that is, an intragenic suppressor and an intergenic suppressor. An intragenic suppressor converses the influence of a mutation at a distinct site in a similar gene.
On the other hand, an intergenic suppressor converses the influence of a mutation at a distinct locus of the gene. It is the intragenic suppressor mutation, which takes place in a similar gene where the occurrence of the first mutation had taken place. Therefore, the mutation, which hides the influence of another mutation at a location, which is different from the location of the original mutation, but taking place in a similar gene can be illustrated as the intragenic suppressor mutation.
