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.
Answer:
In eukaryotes, it occurs in the chloroplast. In prokaryotes it does it in the cytoplasm.
Explanation:
Prokaryotes don't have organelles such as the mitochondria and the chloroplast, it just has cell membrane, which its only function is to protect the cell and is unable to generate chemical processes; the DNA, which stores and manages only the genes, which would be affected if exposed to a chemical process like photosynthesis; and the cytoplasm, which stores the materials that the cell needs, where photosynthesis occurs. Eukaryotes have chloroplasts, which absorb the sunlight and combine it with carbon dioxide and water to realize photosynthesis.

Answer: According to Darwin theory of evolution the struggle for existence is considered as major part for competition among living things.
Explanation:
Coexisting species that belong to the same genera compete for same kind of resources for their survival. Some phenotypic variations gives an survival advantage over others. The superior ones dominate the inferior ones and compete for resources. The one who receives the resources like mates, food, shelter, and others the chances of survival also increases considerably.
