Susan is planting her garden and choosing plants at the local plant nursery. She tells the clerk that she wants to plant perenni
topjm [15]

Answer:

C. Sprout every year, year after year

Explanation:

The perennial plants are the plants that live for more then two years, thous some may argue that they are plants that live more then three years. Whichever the case, they are not short-lived plants, but are capable of surviving for numerous years, unlike the annuals and biennials. Theoretically, the shrubs and trees would fall into this category, but they are classified separately, and this term is not used for them, but for smaller plants that do not have or have very little woody parts. These plants tend to sprout every year, and even though they seemingly die in the autumn, their roots are alive, and they emerge and grow again in the spring, sprouting again. That process repeats itself for numerous years.

To trace our maternal lineage, we observe mutations that have accumulated in our mitochondrial dna (mtdna). in the dna isolation
Sergio [31]
In the coding region, natural selection tends to eliminate all of the mutations because of the high importance these regions have. The coding region contains genes that synthesize proteins and the changes in the DNA sequence can have devastating effects on the cell. Therefore, there are very few differences in the sequences of coding regions that can help us trace the lineage.
On the other hand, in the non-coding regions, the mutations often accumulate because they have little effect on the cell and the adaptive value of the organism. This enables us to trace up the lineage by comparing the sequences and seeing the differences in the sequences.

algol [13]

I think it's option four because as far as I know, red/green color blindness is an example of a recessive, sex-linked trait (encoded on the X chromosome), which results in much more men to suffer from it than women.

Hope that helps!
