blagie [28]

Answer:

C. 100 percent

Explanation:

The woman is heterozygote: AO, while the man is homozygote: BB

By crossing the two:

AO   x  BB

A+B, A+B, O+B, O+B

AB, AB, OB, OB

We have two AB and two OB offspring. Both AB and OB are heterozygotes.

Thus all their offspring will be heterozygous.

<em>Had the question asked what proportion will be OB, the answer would have been 50%.</em>

Since the question asked, what proportion will be heterozygotes and not about the specific genotype, the correct answer is C. 100 percent

Dafna11 [192]

Ionic bonding involves electrostatic interactions between oppositely charged ions, and can significantly enhance the binding strength of biomolecules immobilized to materials.

A chemical link known as an ionic bond occurs when an electron is transferred from one atom to another. Ionic bonding requires the presence of an electron acceptor and an electron donor, which is frequently a metal (often a nonmetal). Electrovalence is the process of moving electrons. A positive ion, also known as a cation, is created when an atom loses one or more electrons. The other atom that picks up one or more electrons will change into a negative ion known as an anion. The elemental name is modified by adding a -ide at the end to designate the ion that accepts the electron. For instance, the name of the anion of chlorine is chloride while the anion of sulfur is sulfide.

According to what you have learned about the circulatory and respiratory systems, explain how and why your heart changed its rat
maks197457 [2]

Answer:

Your heart changes its rate depending on the activity, so that it can carry blood to your muscles, and therefore it needs to beat stronger if you are performing some exercise, or not so strong if you are sleeping, for example.

Explanation:

Your heart is continuously beating to keep blood circulating throughout your body.

So, here it is why your heart changes its rate: Its rate changes depending on your activity level; it is lower while you are asleep and at rest and higher while you exercise to supply your muscles with enough freshly oxygenated blood to keep the functioning at a high level.

And how: depending on your activity level, your heart has to pump enough blood to your muscles. Blood carries needed oxygen and other nutrients. Muscles need more blood sugar than any other tissue especially when working hard. To supply your muscles with oxygen your heart needs to beat faster, and this builds up your heart muscles.
