Answer:
The people who agree on xenotransplantation are those who have severe problems such as heart problems and failure of the kidneys. Xenotransplantation, while it is still being experimented with, is a possibly life-saving option for people with these illnesses. Another reason why people agree on Xenotransplantation is that because it could potentially supply us individuals with an unlimited indefinite quantity of things such as cells, tissues, and organs for humans.
Answer is A. A population becomes separated by environmental factors into two groups that do not reproduce with one another.
When a population of a species become geographically separated then gene flow between them stops. Over a period of time, the population may become genetically different in response to the natural selection due to different environments. Selection and genetic drift will act differently on these two separated populations. This will results into two separate species. This type of speciation is called allopatric speciation.
Answer: Option A
Explanation:
The effector response that increases the body is not associated with vasodilation of dermal blood vessels.
The skins's immense blood supply helps in temperature regulation of the body. The dilated blood vessels helps in heat loss and lowers the body temperature.
Unlike, them the vasoconstriction retains heat and increases the body temperature.
So, the correct answer is option A
Answer:
interaction of light and atoms
emission and absorption of light
Answer:
Natural selection will favor red deer that produce a dozen or more offspring that survive for at least a year.
Explanation:
Natural selection results in adaptation, which means the increase of the aptitude phenotype. Aptitude is the contribution of each genotype to the next generation.
Natural selection is the result between the individual phenotype and the environment that determines the destiny of genes. It is the differential capability of individuals to leave offspring.
Aptitude (or fitness) is the phenotype that results in the survival, fertility, and capability of having a mate. It is a way of measuring the individual ability to leave fertile offspring. Aptitude must be significant to the natural selection act in its favor.
Natural selection, eventually, will favor red deer that produce a dozen or more offspring that survive for at least a year. These animals have more chances of leaving fertile descendants that will be able to grow, develop, survive, and reproduce. They have a higher aptitude than those individuals that only have four fawns during their lifetimes. These animals have fewer probabilities of leaving survival descendants able to reproduce.
