The allosteric inhibitory effector BPG binds to both the A form and the F form. Both forms show a lower affinity for O2 in the p

resence of BPG. However, the inhibitory effect of BPG is larger for HbA. The different O2 affinity indicated by the curves has been attributed to different BPG affinity for the two Hb forms. Complete the statement.
BPG binds tighter to _____________ which ____________its affinity for O2.

Answer:

HbA; lowers

Explanation:

The BPG in our blood stands for Bisphosphoglyceric acid. It is known as by its name as 2,3-Bisphosphoglyceric acid. It is present in our blood in the red blood cells. It binds with more affinity towards the de-oxygenated hemoglobin as compared to the  oxygenated hemoglobin.

Hemoglobin in blood delivers oxygen to our tissues moire efficiently. It is abbreviated as Hb.

Thus BPG binds more tightly towards HbA or adult hemoblobin and which lowers the affinity for oxygen.

Ede4ka [16]

Complete question:

Thinking creatively about evolutionary mechanisms, identify at least

two schemes that could generate allelic polymorphism in a population except natural selection that favors heterozygotes.

<u>Select the two correct answers.</u>

-inbreeding among individuals in the population

-purifying selection against mutational variants of alleles in the population

-continuous migration of individuals with new alleles into the population

-mutations that do not severely affect viability and reproductivity

-genetic drift of alleles common in the population

-events leading to genetic bottleneck effect

Answer:

The two events that might favor heterozygotes among the options are  

  • The Continuous migration of individuals with new alleles into the population
  • Mutations that do not severely affect viability and reproductivity.  These might favor heterozygous frequencies.

Explanation:

Due to technical problems, you will find the complete explanation in the attached files.

Upon examining a sample consisting of 100 cells, you find the following distribution of cell phases. If you know that the cell c
Firdavs [7]

Answer:

the time that cell spend in prophase is 30 minutes

Explanation:

The computation is shown below:

= Number of cell ÷ sample

= 25 ÷ 100

= 1 ÷ 4

Now it takes two hours

So,

= 1 ÷ 4 × 2 hours

= 0.5

This 0.5 represent the 30 minutes

Hence, the time that cell spend in prophase is 30 minutes
