Why don't negative mutations usually increase in frequency in populations?
Valentin [98]

Answer:

Within a population, each individual mutation is extremely rare when it first occurs; often there is just one copy of it in the gene pool of an entire species. But huge numbers of mutations may occur every generation in the species as a whole.

How much energy is produced by each type of macromolecule
german
<span>The amount of energy you'll get from carbohydrate, protein and fat is measured in calories per gram. Fats have the most energy and proteins have the same amount as carbohydrates, but their value as a source of energy is determined by more than the calories gained from one gram. Other factors, such as your activity level and diet, impact which macronutrient is used for energy.</span>

What is the path of H+ions through the thylakoids
Mariana [72]

Answer and Explanation:

Hydrogen ions in the thylakoid space form an electrochemical gradient because of the difference in the concentration of protons (H+) and the difference in the charge across the membrane that they create. This potential energy is stored as chemical energy in ATP through chemiosmosis. The hydrogen ions are allowed to pass through the thylakoid membrane through an embedded protein complex called ATP synthase. Energy from the electron fuels membrane pumps that actively move hydrogen ions against their concentration gradient from the stroma into the thylakoid space. The photon causes an electron in the chlorophyll to become excited.

If a person with o blood type produces offspring with a person with b blood type, then what percentage of their offspring will b
Marysya12 [62]

Answer:

In humans, blood group is determined by three alleles I^{A}, I^{B}, and i.

I^{A} and I^{B} are co-dominant whereas i is recessive to other two.

Thus, if a person with blood group O produces offspring with blood group B then the other parent must contain I^{B} allele.

The genotype of other person can be I^{A}I^{B}, I^{B}I^{B}, or I^{B}i.

There is only one condition in which the person can have offspring with blood group O that is, when the other parent is I^{B}i.

In this condition, the probability of an offspring to have blood group O is 50%.

In other conditions, the probability of an offspring to have blood O is 0%.
