Answer:
vacoule is ur right answer
The chemical nature of an atom, that is , the chemical properties of a specific element, is determined by the number of protons in the nucleus<span>. This number of protons is called the </span>atomic number<span>. The mass of the atom, its atomic mass, depends upon both the number of protons and upon the number of neutrons present in the nucleus (remember that the mass of an electron is so small that it is simply ignored for the purpose of establishing the atomic mass).</span>The difference between atoms, ions and isotopes is the number of subatomic particles.<span> An atom is the basic building block of matter, the smallest molecule of an element that exists and that cannot be chemically divided by ordinary means. Each atom is comprised of protons, neutrons and electrons. In ions, the number of electrons differs, and in isotopes.

Answer:
a and b
Explanation:
The growth of adipose tissue in newborns is directly linked to the fact that they do not have proper body temperature control, so fat acts as a thermal insulator in order to maintain a constant temperature, also, breast milk density can also influence baby fat gain.
For the first six months the baby still has a lot of fluid retention and so it may give the impression that he is getting fatter, but after the first six months until the end of the first year, the baby tends to lose this fluid, decreasing on average 10% of body weight.
<u>Girls</u> in adolescence and pre-adolescence have a tendency to gain weight due to the enormous hormonal load they receive at puberty, as well as other factors such as poor diet.
The same does not happen as often in <u>boys</u> because a good part tends to have a "leap" growth in puberty, favoring weight loss. The process of fattening in teenage boys is more associated with sedentary practices and consumption of junk food.
Answer:
The seeds perform the following functions: They help in germination of the new plant. The seeds contain food reservoirs in the form of cotyledons and endosperm. The seed coat is protective in nature which protects the embryo inside.
I would say b and a don't quote me if I'm wrong :P
