Suppose that diploid cells of the seminiferous tubules encounter errors during the cell cycle and mitosis. This results in the primary spermatocytes having a 4n number of chromosomes. Assuming that meiosis proceeds normally, which of the following would be true?

a) sperm cells would have an n number of chromosomes. b) sperm cells would have a 2n number of chromosomes. c) secondary spermatocytes would have a 4n number of chromosomes. d) secondary spermatocytes would have an n number of chromosomes.

Explanation:

Primary spermatocytes undergo meiosis for the production of sperm. In meiosis one parental cell produce four daughter cells with half the number of chromosomes in each cell.

As given here; primary spermatocytes having a 4n number of chromosomes  so after meiosis, each sperm cells would have a 2n number of chromosomes, because each daughter cell contain half the number of chromosome as compared to parental cell, so 4n parental cell will produce 2n daughter cell in meiosis.

because of

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)

7. producer

8. consumer

9. prey

10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)
