Answer:
In the result of meiosis, testes produce 4 small mature sperm while ovaries produce 1 large egg cell.
Explanation:
Meiosis produces gametes (sex cells). Sex cells are eggs in females and sperm in males.
In the female, ovaries produce four haploids (3 polar bodies and 1 immature egg) under meiotic division. Polar bodies die because of the unequal division of cytoplasm. The immature egg matures into a large ovum/egg every 28 days during the menstrual cycle that is able to fertilize.
In the male, meiosis occurs in testes that produce 4 spermatids that mature into 4 small sperms. Testes produce several hundred million sperms every day under meiosis. These sperms are able to fertilize.
Nevertheless, if we want to compare their numbers based on meiotic division, we would say that they will be in the same ratio (1:1) at the end of each meiosis cycle for males and females.
Explanation
Organisms from kingdom Plantae does have cell walls. Organisms from Animalia does NOT have cell walls. Fungi also does have cell walls. Prokaryotic Eubacteria includes bacteria with cell walls. Therefore, the organisms with cell walls are I, III and IV. The correct answer is C.
Answer
