Answer:
Answer is hypodermis .
Explanation:
The hypodermis which is also known as the subcutaneous tissue layer, is found lying beneath the dermis and act as a passageway or channel through which blood vessels and nerves passed. It is made up of fat and connective tissues.
It acts as an insulator, this, help in keeping the body temperature stable.
Answer: D) independent assortment
Explanation: independent assortment This is the process, first proposed by Mendel, where the chromosomes move randomly to separate poles during meiosis. Variation exists, in part, because the traits inherited through one gene will be inherited independently of the traits inherited through another gene because the genes reside on different chromosomes that are independently assorted into daughter cells during meiosis.
A) <u>Mutation</u> is the original source of variations for plants and other organisms which develops differences among their respective species
Explanation:
Genetic variation leads to the natural differences between each individual and among individuals of a species. The main cause for this variation is due to alleles that cause variations in the composition of genes or the DNA sequences.
A mutation is a genetic variation which leads to the creation of a new allele in a species population. Each variation in the DNA sequence leads to an allele formation and each allele leads to a difference in character or trait between individuals since they are the alternate version of the original genes.
Although genetic variations could be brought about by crossing over, random fertilization, or independent assortment; mutation is the original source because it provides the basic raw material for all the evolutionary changes.
Well, not exactly like some parents have blue eyes and they have a dominant brown eyed child. This can happen because of the gynotype. The history of the child’s parents probably have some brown eyes which caused the child to have brown eyes. But usually the parent does express a dominant trait like the child.
Answer:
<u>-temperature and rainfall</u>
Explanation:
Terrestrial biomes are defined as regions of similar vegetation and climates. Certain types of vegetation have specific growth requirements for their optimal water and temperature. They tend to thrive within regions where these needs are met, thus making up the dominant plant types.
At or close to the equator, biomes are warmer due to the high intensity of sunlight (the equatorial regions the most sunlight), and warmer air holds more moisture, making the regions more prone to rainfall.
