B. Anions have more electrons than protons, giving them a negative charge.
D. Cations have more protons than electrons, giving them a positive charge.
Explanation - Ions are the result of atoms or molecules that lose or gain electrons. If an atom or a molecule is positively charged then it is called as cation and if it has negative charge then it is called as anion.
Cations have positive charge because the atom has lost its electron while anions have negative charge because the atom has gained the electron. The number of protons is more than the electron in cations and less in anions.

What's up? this organelle is known as a vacuole. best of luck with your studies!
The process is likely to be triggered by the formation of the layers. Zygote is the structure that forms when a sperm fertilizes an egg, the zygote then divides many times by the process of mitosis to form an embryo. That is, it forms two cells, then four, then eight and so on, up to the eight stage the cells are identical and are called embryonic stem cell, which then develop into any specialized cells type by differentiation, that the growing embryo needs, such as the nerve cells, blood cells, among others.
