2 - я не знаю

3 - верно

4- помоему тоже правильно!

Answer 3

Statement 1: "в результате мейоза получаются 4 гаметы из 1 материнской клетки."

This statement is incorrect. During meiosis, a type of cell division that produces gametes (sex cells), one diploid cell undergoes two rounds of division to produce four haploid cells. Each haploid cell is a gamete. Therefore, the correct statement would be that in meiosis, four gametes are produced from one mother cell.

Statement 2: "шизогония-это способ бесполого размножения животных типа споровики."

This statement is incorrect. Schizogony, also known as multiple fission, is a method of asexual reproduction found in certain protozoa and some parasitic worms. It involves the division of a single cell into multiple daughter cells. Sporozoans, on the other hand, reproduce through a process called sporogony, which involves the formation of spores. Therefore, the correct statement would be that schizogony is a method of asexual reproduction in certain organisms, not specifically in sporozoans.

Statement 3: "при оогами одна гамета не имеет жгутиков."

This statement is correct. Oogamy is a type of sexual reproduction in which a large, non-motile egg cell (ovum) is fertilized by a small, motile sperm cell. In oogamy, the sperm cell typically possesses a flagellum (tail) for movement, while the egg cell does not have a flagellum or any other means of independent movement. Therefore, one gamete (the egg) does not have flagella.

Statement 4: "размножение, при котором новый организм образуется из яйцеклетки без участия сперматозоида, называется полиэмбриония."

This statement is incorrect. Polyembryony refers to a phenomenon where multiple embryos develop from a single fertilized egg or from multiple eggs within the same organism. It is not specifically related to the development of an organism from an egg cell without the involvement of a sperm cell. The correct term for the latter scenario is parthenogenesis, which is a form of asexual reproduction in which an unfertilized egg develops into a new individual.
