I believe the answer is C.
Answer:
Necessary for the transport of dietary lipids. (Ans. C)
Explanation:
Lacteals are specialized lymphatic capillaries which helping in to absorb dietary fats that are present in the villi of the small intestine. With the help of bile, triglycerides is emulsified, and with the help of enzyme lipase, triglycerides is hydrolyzed, these (emulsified and hydrolyzed) results in the mixture of di, monoglycerides, and fatty acids.
The villi are finger shaped, and tiny in size which helping in to increase the surface area. Intestinal structure is known as lacteals which helps in the transport of glycerol, and fatty acids aside from the small intestine in the lymph.
Answer:
The involvement of more than two genes.
Explanation:
The polygenic characteristics have many phenotypes because more than two genes governs the phenotype of individual organism. The single gene contains a pair of alleles that codes for two phenotype and two genes will code for 4 phenotype. Thus, more than two genes for example, three genes will have six phenotypes.
The skin color and height are polygenic characterstics in humans.
Answer:
For organisms like algae and other protists, certain bacteria, and plants, photosynthesis is a critical process. Why is the process of photosynthesis essential for organisms like these to perform?
All animals depend on plants for survival as they are the only producer that provides others feeds on the trophic level or food chain, without photosynthesis plants would not be able to produce food which is at the detriment of animals
Explanation:
These are all true except <span>"D. Natural selection usually causes a species to change suddenly," which is false. Natural selection and the subsequent changes to a species takes many thousands of years to have observable results. </span>
