Answer:
The genome of an organism is inscribed in DNA, or in some viruses RNA. The portion of the genome that codes for a protein or an RNA is referred to as a gene. Those genes that code for proteins are composed of tri-nucleotide units called codons, each coding for a single amino acid.

Answer:
<u>B. Animals do not use carbon dioxide as an energy source; they use carbohydrates.</u>
Explanation:
The most readily form of energy that an animal requires is carbohydrate molecules. Monosaccharide carbohydrates can be easily broken down and hence are the best sources of energy. Carbohydrates are broken down in the process of cellular respiration to generate ATP. ATP is the energy driving molecule which is required by every cell of an organisms body to carry out its normal metabolic functions. Hence, animals use carbohydrates as a source of energy, not carbon dioxide.

Explanation:The concentration of a solution can be given in moles of solute dissolved per kilogram of solvent.
This is known as molality.
(Not to be confused with molarity which is a different measure of concentration.)
Molality is given the symbol m.
molality = moles of solute ÷ mass of solvent in kilograms
m = n(solute) ÷ mass(solvent in kg)
A solution containing 3 moles of solute per kilogram of solvent for example, is said to be 3-molal or 3m.
