Genes are heredity that are transferred from a parent to offspring and determine a physical or mental characteristic for the offspring
A fossil is the bone of a long dead animal that has been in the ground Harding for thousands to millions of years.
<h2>C) option is correct </h2>
Explanation:
Natural selection as proposed by Darwin is a selection pressure which operates in a population and allow the best fitted genotype to survive in changing environmental conditions and eliminate the other genotype which are not fit
Causes of natural selection include: Genetic drift, mutation(changes allelic frequency) and sexual selection
In the given example, condition necessary for natural selection to occur on the mouse population is traits that affect the survival of the mice vary among individual mice, in this condition superior genotype will get the opportunity to reproduce and inferior genotype does not get opportunity to reproduce thus their genotype in population does not increase rapidly and hence they become eliminated leading to genetic drift
I believe the answer is the lacteals.
Lacteals are structures that are in the middle of each villi; they are lymphatic capillaries that absorbs dietary fats in the villi of the small intestines. Triglycerides are emulsified by bile and hydrolyzed by the enzyme lipase, resulting in a mixture of fatty acids and monoglycerides. The lacteals merge to form larger lymphatic vessels that transport chyle to the thoracic duct where it is emptied into the blood stream at the subclavian vein.
