Answer 1

Е) Размножаются НЕ половым путём

Answer 2

Answer:

The number of sperm involved in fertilization in conifers is 2.

Explanation:

Conifers, also known as gymnosperms, have a unique reproductive process. In conifers, the male gametophyte (pollen grain) contains two sperm cells.

During fertilization in conifers, one of the sperm cells fertilizes the egg to form the zygote, while the other sperm cell fuses with the polar nuclei to form the endosperm, which provides nutrients to the developing embryo.

Therefore, the correct answer is B) 2.
