A homozygous green (yy) pea plant is crossed with a heterozygous yellow (Yy) pea plant. The phenotypic ratio of the offspring is 50 percent Yy and 50 percent yy.
Further Explanation:
Genotypes help in the genetic makeup of any individual. Phenotype describes as a physical characteristic of an individual. The genotype is responsible for the phenotypes of any individual. If two copies of the same alleles present in an organism, its genotype is called homozygous. If two copies of different alleles present in an organism, its genotype is called heterozygous.
When a homozygous dominant individual is crossed with the homozygous recessive individual the resultant offspring has the genotype which is heterozygous and phenotype which is dominant. All possible genotypes of the parent as well as offspring are graphically represented in a Punnett square.
In the given punnet square below, the parent homozygous green plant having a genotype yy is crossed with the parent heterozygous yellow plant having a genotype of Yy. The resultant offspring of filial generation tends to be 50 percent of Yy which means heterozygous and 50 percent yy which means homozygous.

Answer:
Oxygenated blood is blood that has been oxygenated, it has a large percent of oxygen.
Explanation:
Oxygenated blood is blood that has been oxygenated by the lungs, it then is pumped all over the body.
(oxygenated- enriched with oxygen)
Synonym: Oxygen rich blood
(B) introduction of a new parasite
(C) introduction of a new mutation
(D) interspecific competition for limited resources
(E) habitat destruction
Please explain the work behind the solution
C is the correct response to this query: the introduction of a new mutation. Mutations are modifications to an organism's genetic code; while they may result in phenotypic alterations, they seldom result in extinction.
If a new predator is able to hunt down or outcompete an existing species, or if it spreads a disease or parasite, it can lead to extinction. If a novel parasite can spread swiftly and generate significant mortality rates, it may lead to extinction.
If one species is more suited and can outcompete the other species for resources, interspecific rivalry for scarce resources can lead to extinction. Last but not least, extinction may result through habitat damage if it results in a decrease in food, water, or shelter. something an organism requires to survive.
In conclusion, the introduction of a novel mutation is not seen to be a probable cause of extinction since mutations are often too gradual and the changes they bring about are typically too minor to do so.

It be unreasonable to conclude that this level of UV radiation exposure is harmful to these cells because, There is no control group and we don't know how many cells would have died after 3 days with normal UV exposure.
Explanation:
The researcher in the given example shows the effect of UV radiation and its effects to the cells. He does not tell about the group that did not receive the UV radiation and their effects. A control group is very important in a research because it can be compared with the result obtained by some experiment effects. It is a group in an experiment in which the treatment is not given.
The results can be compared with the group under treatment with the group that did not undergo any treatment. Since, there is no control group in this experiment, we can not determine how many cells that were exposed to normal UV radiation died after 3 days, it would be unreasonable for getting the conclusion of how harmful UV radiation exposure to these cells.
a clam basically extends with the fragile outer system frame, therefore it retracts after a while, one of the main reasons we retrieve pearls from shells and clams.

C. touch
D.. sound
The answer would be E. smell
