<span>For a species with four pairs of chromosomes, 16 gametic combinations are possible</span>
If a species has 4 pairs of chromosomes will mean that the species has 8 alleles. In mating, only one of the pair will be inherited. In this case, the probability of the combination will be 2^4 assuming all the genes is heterozygote.
Answer:
Lithotrophy uses inorganic molecules as the initial electron donors.
Explanation:
Lithotrophy is also referred to as chemolithotrophy is a diverse group of organisms using inorganic substrate of mineral origin to obtain reducing equivalents for use in biosynthesis or energy conservation. It acquires energy by oxidation of inorganic electron donors, although electron acceptors may be organic or inorganic. Lithotrophy uses inorganic molecules as the initial electron donors.

Answer:
3 (Cells carry out the respiration process)
Explanation:
Cellular respiration is a metabolic (catabolic) process common to all living things as all living things need energy for their life processes.
Respiration is the biochemical process in which the cells of an organism obtain energy by breaking down organic molecules in presence or absence of oxygen (aerobic or anaerobic) resulting in the release of Carbondioxide (CO2), water and Adenosine triphosphate (ATP).
Food molecules (containing stored energy in their chemical bonds) absorbed after digestion are broken down and the energy within their molecules are freed. This freed energy in form of ATP, is used to power the organism's movement and physiological functions.
Note that, ATP is an energy carrying molecule and a usable form of energy by cells. This is so because ATP releases energy quickly. Energy is released from ATP when the end phosphate (Pi) is removed to become ADP (adenosine diphosphate), which is a low energy molecule.
Aerobic cellular respiration consists of Glycolysis, Kreb's cycle and Oxidative phosphorylation. A total of 38 ATP molecules is produced in the cytosol of prokaryotes while a total of 36 ATP molecules is produced in the mitochondria of eukaryotic cells.
