The correct answer is B The young sun's solar winds pushed gases outward to the outer solar system.
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.
A common resource (or the "commons") is any scarce resource, such as water or pasture, that provides users with tangible benefits but which nobody in particular owns or has exclusive claim to. A major concern with common resources is overuse, especially when there are poor social-management systems in place to protect the core resource.
The continental drift affects living organisms in that it causes changes in climates which puts selective pressure on organisms, causes changes in habitats, including when large amounts of shallow marine habitat were lost in the formation of Pangea. Additionally continental drift may cause an increase or decrease in competition among different species and also it happens so slowly that it does not affect living organisms
