Actually Welcome to the Concept of the Biology
So the answer is,
Genetic Information is bundled into packages of DNA known as Chromosomes.
Answer:
D. proportion of arginine and lysine amino acids in the histone proteins.
Explanation:
Epigenetic modifications are one of the main reasons of methylation and de-methylation, acylation and de-acylation of histone proteins that trigger the transcriptional process. All of these mentioned modification causes the change in the ration of lysine and arginine residues and these are the main reasons that affect the structure of chromatin as required.
<h3><u>Answer;</u></h3>
B. When an antibiotic is used, bacteria that have a natural variation for resistance to the antibiotic have a greater chance of survival.
<h3><u>Explanation</u>;</h3>
Antibiotic resistance is a consequence of evolution via natural selection.
The antibiotic action is an example of environmental pressure to bacteria, therefore; those bacteria which have a mutation allowing them to survive will live on to reproduce.
They will then pass this trait to their offspring, which will be a fully resistant generation.
It is measured by Richness and Evenness.
Richness- the number of groups (or species) related genetically or functionally.
Evenness- the proportions of the species or groups on a site.
