Answer:
The answer is C. DNA from the S bacteria is necessary for bacterial transformation to occur.
Explanation:
When heat-killed nonvirulent S bacteria will be treated with enzymes that degraded DNA it will destroy the genetic information required for cell survival. DNA is very essential for an organism and is called the molecule of life. DNA degradation is also a part of cell death called apoptosis. That's why all the samples grew except the one where DNA was enzymatically degraded.
The exocrine gland indicated by an arrow is the liver.
<h3>What is an
exocrine gland?</h3>
A gland that makes substances such as sweat, tears, saliva, milk, and digestive juices, and removes them through a duct or opening to a body surface.
Examples of exocrine glands include sweat glands, lacrimal glands, salivary glands, mammary glands, and digestive glands in the stomach, pancreas, and intestines.
Thus, the exocrine gland indicated by an arrow is the liver.

Answer: Bacteria lack a mechanism for splicing out introns
Explanation:
Factor VII gene is 186k nucleotides long while the protein is 2332 amino acids long. <u>This lenght discrepancy is due to introns interrupting gene</u>, because the cell first transcribes the entire gene and then cuts introns out of the transcript. At the end, it splices the remaining pieces. Prokaryotes don't perform splicing so it can not edit out introns from the primary mRNA transcript. To produce an eukaryote gene in prokaryotes it is necessary to use a reverse transcriptase to get a cDNA sequence without the introns, and then insert that into a bacterial genome.
Answer: the same amount of DNA normally present in the parent cell
Explanation: somatic cells are diploid and they have the same amount of DNA that their parent cells have
