Answer:
Testes
Explanation:
In the given question, the male reproductive structure has been provided and in this male reproductive structure, only "Testes " which occurs in the pairs are known to form the male gametes.
The male gametes called sperms are formed from the spermatocytes which by the process of meiosis produces four spermatozoa which later mature into the spermatids and sperms.
Thus, Testes is correct.
Atoms gain electrons to form anions.
Atoms lose electrons to form cations.
Back in middle school, my chemistry teacher taught me a good way to remember whether an ion was a cation or an anion. When an atom loses an electron, it becomes positive, and when an atom gains an electron, it becomes negative.
Cation sort of sounds like “cat,” which is positive (Yay! Cats!).
Anions, on the other hand, sounds like “onion,” which is negative (Ew! Onions!).
There’s other ways of memorizing it, but this way was the easiest for me.
