How does sexual reproduction compare to DNA transfers in prokaryotes? (2 points)

Biology
1 answer:
Andreyy893 years ago
7 0

Answer:

The correct answer is b. I and II

Explanation:

Sexual reproduction is present in higher forms of life and absent in prokaryotes like bacteria. Sexual reproduction results in greater evolutionary changes due to the fusion of two different gametes from two different individuals of a species.

Therefore sexual reproduction helps in increased genetic diversity in higher forms of life. In prokaryotes like bacteria, genetic diversity is maintained and increased through DNA transfer from one bacterial cell to another with the help of a process known as horizontal gene transfer.

Bacteria have sex pilli which is used to introduce the genes to the other bacteria. By this process, they increase their genetic diversity and evolve continuously. So the correct is b. I and II.

nika2105 [10]

Answer:

Control of the cell cycle is necessary for different reasons. When the cell cycle are not regulated, cells could constantly undergo cell division without any form of control which will lead to cancer.

Internal regulation of the cell cycle is necessary to alert the passage of one phase to the next at a set given time. This helps in the overall metabolism of the body.

Answer:

Plato Answer

Explanation:

Embryonic stem cells are plentiful, and they can create every cell in the human body. Researchers can use these cells to create tissues. They can possibly grow new organs in a lab to treat diseased organs. Adult stem cells are rarer in the human body, and they’re limited in the types of cells they can make.

An embryo can’t grow without its stem cells, so people have ethical concerns about their use. Adults can provide consent to donate their stem cells, so there are fewer ethical issues regarding the use of adult stem cells.

A population of white-tailed deer inhabits a certain patch of forest in michigan. Which group of alleles can be considered the g
emmainna [20.7K]

Answer:

the dominant alleles of white-tailed deer in this population only!

Explanation:A group of individuals of the same species that interbreed with each other is known as a population. The study of change in genetics is called population genetics which includes genes and alleles.  

Complete set of genes and their alleles that are present in a population is called gene pool. Gene pool includes both dominant and recessive alleles of every gene present in a population that can be transmitted in the next generation.

Population with high genetic pool has high diversity which increases the fitness of a population. As gene pool include all the genes and its allele in a population, therefore, the correct answer is all alleles of the white-tailed deer in this population only.
