Hihi!
The answer would be 2) Plenty of food! If you have plenty of food then the likely hood for more of the population to live would increase, the rest of the causes would cause decrease in the population!
I hope I helped!

pulmonary vein carries oxygenated blood while the other veins carry deoxygenated blood
Answer:
Option A
Explanation:
Options
A. most populations were fixed for a single genotype, but genotypes varied among populations
B. average heterozygosity was declining steadily over time
C. individual populations were polymorphic for several loci and most populations were genetically similar to one another
D. all populations were fixed for the same allele at each locus studied
Solution
As per the study conducted by Templeton, it was found that human affect the biodiversity at all biological levels such as genetic, ecosystem, species etc. and behind genetic variation two important factors are genetic drift and gene flow.
Both the gene flow and genetic drift produce opposite results as genetic drift increase variation with in the species but decrease variation with in the local population and the opposite of this happens in gene flow.
Genetic drift has actually lead to speciation of collared lizards among themselves for a specific genotype
Hence, option A is correct
Water moves from the ground or oceans into the atmosphere through a process called evaporation. It's a process that happens on a molecular level when the molecules of water are really energized and rise into the air.
<em>Water evaporates </em>from the surface of the sea into the air. The water vapors condensed in the air and take the shape of clouds. And when the water vapors become heavier than air its starts raining. This is how the ocean water turns into rain and the cycle goes on.
