A person with severe edema is likely to be administered which medicine?

In the cell, which organelle has the function of using oxygen in the breakdown of glucose, releasing energy and carbon dioxide?

tester [92]

<span>Aerobic cellular respiration uses oxygen and yields many more ATP molecules than anaerobic cellular respiration, which does not use oxygen and yields only 2 ATP molecules. There are three stages in the process of transforming glucose to ATP: glycolysis, the citric acid cycle, and the electron transport chain.</span><span>

Which statements about the modification of chromatin structure in eukaryotes are true? Select all that apply.

Crank

Ans.

Chromatin molecules are made up of DNA and histone proteins. Modification of chromatin structure include covalent, post-translational changes in histone proteins, present in chromation. Acetylation and methylation are two important histone modifications that affect structure of chromatin molecules.

Acetylation involves addition of an acetyl group to histones that increases transcription of DNA by loosen the association between DNA and nucleosome.

Methylation involves addition of a methyl group to histones that results in condensation of chromatin molecule and thus, decreases transcription of DNA.

Both acetylation and methylation are reversible processes.

Many chromatin modifications are genetic, means they can pass from one generation to another generation, called epigenetic modifications.

Thus, options B), C), D), E), and F).

Consider a locus with two alleles - B and b. B is dominant, while b is recessive. There is no mutation. B has a selective advant

Marat540 [252]

Answer:

0.09

Explanation:

<h3><u>Before selection</u></h3>

Total number in population = 1000

Genotype frequencies

Genotype frequency of BB = 500/1000 = 0.5

Genotype frequency of Bb = 250/1000 = 0.25

Genotype frequency of bb = 250/1000 = 0.25

Allele frequencies

Allele frequency of B = BB genotype frequency + half of the Bb genotype frequency = 0.5 + (0.25/2) = 0.625

Allele frequency of b = bb genotype frequency + half of the Bb genotype frequency = 0.25 + (0.25/2) = 0.375

<h3><u>After selection</u></h3>

We are told that after selection, the genotype frequency of bb is changed as they become 50% less fit. This means the frequency of bb individuals changes from 250 to 125 individuals (50% reduction).

Now the total number of individuals is 500 + 125 + 250 = 875.

Genotype frequencies

Genotype frequency of BB = 500/875 = 0.57

Genotype frequency of Bb = 250/875 = 0.29

Genotype frequency of bb = 125/875 = 0.14

Allele frequencies

Allele frequency of B = BB genotype frequency + half of the Bb genotype frequency = 0.57 + (0.29/2) = 0.715

Allele frequency of b = bb genotype frequency + half of the Bb genotype frequency = 0.14 + (0.29/2) = 0.285

<h3><u>Change in frequency of B after 1 generation</u></h3>

0.715 - 0.625 = 0.09
