Answer:

The model appears to show the carbon dioxide molecules entering the blood cell and the oxygen molecules existing the cell.

kicyunya [14]3 years ago
3 0

Answer:

Explanation:

The model doesn’t clearly show that gas exchange happens in the alveoli through the capillaries. The model can also be easily misinterpreted. Because the model doesn’t show where this gas exchange is taking place, it looks like the blood picks up oxygen, delivers it to the body, and then comes back and expels the carbon dioxide it collects. Clarifying that this gas exchange is taking place in the capillaries would eliminate this confusion.

A woman without hemophilia marries a man with hemophilia they have a daughter with hemophilia what is the genotype of the mother
Alecsey [184]

Answer:

Mother- XXH

Father- XHY

Explanation:

The mother is a carrier for hemophilia and since the disease is sex linked and found on the X chromosome, only one of the alleles has that H allele attached to it. The father is male so he only has one X chromosome, which is why he is effected by the disease and not just a carrier like the mother.

List and describe the purpose of each component of the restriction enzyme digest. Why do some tubes have no restriction enzyme?.
Arisa [49]

A typical restriction digestion reaction includes the DNA template, the desired restriction enzyme, a buffer, and occasionally BSA protein.

<h3>How come a restriction enzyme wouldn't function?</h3>

You should always check the expiration date, confirm that the enzyme has been stored at -20°C, and check the temperature of your freezer (do not allow temperatures to surpass -20°C, since many freeze-thaw cycles may cause an enzyme to lose action).

<h3>How does a restriction digest work?</h3>

With the aid of specialized enzymes known as restriction endonucleases (often referred to as restriction enzymes or REs), restriction digestion is the process of breaking down DNA molecules into smaller fragments.

What are the three main classifications that describe galaxies? By what one visible
sp2606 [1]

Answer:

Spiral Galaxies, Elliptical Galaxies  & Irregular Galaxies

Explanation:

How did galaxies originate? Astronomers believe that after the big bang, the explosion which began the universe 10 billion to 20 billion years ago, gravity began to compress masses of free-floating gas. Two main theories, bottom-up and top-down, explain what happened next. According to bottom-up theories, clusters began to form and assembled together into the larger units we know as galaxies. Top-down theories suggest that galaxies formed first, and the stars and other objects within them were subsequently produced. They categorized different galaxies to maintain their tests from the other galaxies.
