Answer:
answer C.
Explanation:
waste can be removed from the cells of the body.
Answer:
Somatic mutations – occur in a single body cell and cannot be inherited (only tissues derived from mutated cell are affected) Germline mutations – occur in gametes and can be passed onto offspring (every cell in the entire organism will be affected)
Explanation:
a. True
b. False

If a white horse and a black horse are bred together, what percentage of the offspring will be roan and express both colors in their hair?1 point)
100 percent
0 percent
25 percent
50 percent
The dominant traits are those that are expressed phenotypically, whereas recessive traits are masked by the dominant traits.
The dimples are the traits, which are expressed phenotypically.
Let the alleles for the heterozygous parent with dimples be Dd. The other parent not having dimples will have the genotype dd.
The combination between the Dd and dd will result in:
Dd, Dd - heterozygous combination of alleles
dd, dd - purebred for the alleles
Similarly, the genotype of the hair color of the horse is white and black .
The cross between the parental genotype will result in 100% heterozygous offspring with genotype
The result will be due to codominance, in which both the characters of the parent will be expressed in the offspring such that the horse will have black and white colors.
Therefore, the answers will be 50% and 100%.

Answer:
1) 50 percent
2) 50 percent
Explanation:
(2) most changes from generation to generation are the result of mutations
(3) part of the population of organisms always remains stable
(4) different traits inherited by offspring have different survival value
Answer:
Option B, most changes from generation to generation are the result of mutations
Explanation:
Through the process of evolution, an individual changes from one generation to other generation. These variations are caused by genetic changes.
Genetic variations are caused by -
a) Genetic mutation
b) genetic recombination
Genetic variation leads to alteration of gene or protein function due to which differences traits arises in an organisms. Thus , it can be said that genetic mutation brings variation in structure and thus leads to evolution of any species.
As long as generations of individuals with the newly developed trait continues to mate and reproduce, new trait becomes common in a population.
Hence, option B is correct
