Answer:
True.
Explanation:
Red blood cells or erythrocytes carry oxygen to the cells of the body so that they can have energy and function properly. This is not the only function of red blood cells. Also, they carry dioxide, which is a waste product that needs to be out of our body. Erythrocytes carry the dioxide to the lungs, specifically to the alveoli. In the alveoli due to the inhalation, oxygen enters our body traveling up to the lungs, specifically to the alveoli, where thanks to the thin wall of it as well as the one on the capillaries that are in contact with it, the dioxide enters the lungs to be expelled in the exhalation, and the oxygen is taken by the red blood cells to be used in the cellular respiration and generate energy to keep the vital functions of our body.
1. False. They are similar, though.
meiosis- A kind of cell division involving having the chromosome number. It is responsible for genetic recombination.
Gametogenesis- It's the process when gametes or germ cells are produced in an organism. They undergo meiosis to form gametes.
2. Spermatogenesis- happens in the testes of males. 4 gametes are produced. Spermatogenesis involves a metamorphosis stage called spermiogenesis. Spermatogenesis produces small, motile spermatozoa
Oogenesis- takes place in the ovary in a female. 1 gamete produced. in oogenesis there is no metamorphosis stage. In oogenesis the ovum is spherical, and isn't motile and is bigger with more food reserves and cytoplasm.
3. Because The one egg cell that results from meiosis contains most of the cytoplasm, nutrients, and organelles.
They are like that because they can't always be faulty and may have at least some spark of truth to this theory also as stated earlier a theory in scientific terms is just an observation so it can't really be turned down hence theory.
Fairly sure that would be secondary succession.
