Answer:
B) Early spermatids have not undergone meiosis and are still diploid.
Explanation:
Spermatids are formed at the end of meiosis in the testes of male. Spermatids are haloid cells in which chromosome numbers are half as compared to their parent cells. An early spermatid has not undergone morphologic changes and is considered less mature than the late spermatid.
Late spermatids undergo morphological changes (spermiogenesis) and they transform into a spermatozoa which is ready to release in the lumen.
This change best illustrates the 3rd answer choice, Loss of Habitat.
The plants aren't migrating, but are rather only surviving in areas where there is enough moisture to support life. The wildflowers are not adapting to grow in dryer conditions, and the species is not going extinct, as there are still some areas where the plants can get enough moisture.

The channels would only let in certain molecules in that would help the cell. The channels would not let some harmful bacteria into the cell this way with channels that only transport one molecule.
It is habitat loss
