Human gametes are _____.A. isogamous
B. anisogamous
C. oogamous
D. none of the above

Answers

Answer 1
Answer: I think the correct answer from the choices listed above is option C. Human gametes are oogamous. Oogamy is form of sexual reproduction where female gamete is significantly larger than the male gamete and is non-motile which is true for human gamete.
Answer 2
Answer:

Final answer:

Human gametes are anisogamous, which means the reproductive cells are different in size. The male gamete, sperm, is smaller and motile while the female gamete, ovum, is larger and non-motile.

Explanation:

Human gametes are B. anisogamous. The term 'anisogamous' means that the gametes or the reproductive cells are different in size. In human beings, the male gamete, or sperm, is smaller and motile, while the female gamete, or ovum, is larger and non-motile. This is a typical characteristic of sexually reproducing species where there are distinct male and female gametes. Isogamous refers to species where the gametes are of equivalent size and morphology, and oogamous pertains to species where a tiny, motile sperm fertilizes a large, stationary ovum, which is primarily in many algae and fungi. So, among the given choices, human beings fall under the category of anisogamous.

B. cnidarian
C. arthropod
D. roundworm

Answers

Is not a sponge, cnidarian or arthropods . The pseudocoelom is specific to any invertebrates with three body layers. So, your answer is D - roundworm 

The correct answer is option D, Round worm

Roundworm belongs to the phylum  Nematodes and some common characteristics of Nematodes are – they are small, slender , un-segmented, smooth and shiny. Roundworm has   a round body just like a spiny –headed worm which do not have segments . Also they possess a body cavity known as pseudocoel in which the internal body organs lie and the body cavity is not lined with mesodermal cells.
