Answer:
<em>The correct option is D) The expression of certain genes is affected by temperature.</em>
Explanation:
There are various factors which control the regulation of a gene. Temperature can be a regulatory factor for certain genes.
Probably, during the warm temperatures, the proteins regulating the fur colour to become reddish brown become activate these genes. As a result, the fur becomes evident.
In the winter, the enzymes controlling the fur might become degraded. A s a result, the genes are not able to express themselves. Hence, a white coat occurs.
Maximum Thrift is a method / philosophy that considers the shortest tree (in number of transformation steps) the best hypothesis about the phylogenetic relationship of a given set of terminals. Transformation step is the cost attributed to the change of character state in a given branch of the tree, be it the change from one nucleotide base to another, amino acids, or the color of an animal's iris. The fewer transformations, the shorter the tree, and therefore the more parsimonious. In this method, what programs do is to investigate as many alternative topologies as possible (or all if their array has less than 25 terminals; see more details below) given their character array. Each will be measured, and the shorter (optimal) trees will be retained as the most parsimonious result.
The population growth would be increasing because 6+5=11, then subtract the 3 that were killed leaving us with 8 deer. :D
