The daughter cells are produced with only half the chromosomes of the parent cell. The correct option among all the options given in the question is option "D". So the main goal of meiosis is actually creating four daughter cells that are by no means similar to the parent cells.
When these daughter cells that
are created combine together and undergo the process of fertilization, then a
zygote is formed and the development of cells starts. The process of meiosis
can be asexual as well as sexual.

B) Embryonic stem cells research requires the use of human embryos.
Ribosomes read information in a DNA molecule and use it to synthesize protein
Answer:
Helium
Explanation:
We know that this atom has two positive particles on the nucleus (protons) with two neutral particles (neutrons). We can also see that it hass two electrons on the orbitals. Knowing this, we can say that the element is Helium.
Helium has a relative atomic mass of 4 and it's atomic number is 2. The atomic number is equal to the number of protons and electrons the atom has, and the atomic mass can be used to calculate the number of neutrons:
Relative atomic mass = Neutrons + atomic number
So we know that:
Neutrons = relative atomic mass - atomic number
Neutrons = 4 - 2 = 2.
