Answer:
In an ancestral elm species, mutations gave rise to the phenotypic trait "winged-seeds". Subsequently, selection favored elm plants with winged-seeds that diverged over time to become a separate species
Explanation:
A mutation is a genetic change in the DNA sequence. In general, mutations have a negative impact on the fitness of the individual (i.e., mutations are generally deleterious) and therefore they disappear from the population. However, there are situations where mutations are beneficial and confer an adaptive advantage, thereby increasing their frequency in the population. In this case, mutations associated with the formation of winged-seeds conferred an adaptive advantage (i.e., higher seed dispersal capacity) to individuals who had this phenotypic trait, thereby these individuals had more chances to reproduce and pass their genes to the next generation. Eventually, Elm plants with winged-seeds accumulated sufficient genetic differences to prevent interbreeding, leading to the formation of a separate species.
The answer would be B) microscope
The first cell to ever be discovered was by Robert Hooke in 1665 using a microscope.
Answer:
C. Ppgg
Explanation:
<u>hetero</u>zygous for flower color would mean the plant carries both P and p
<u>homo</u>zygous for pod color means it would only carry G or g but not both; however, it says that it is homozygous <u>recessive.</u> This tells us that it will be carrying only the non-dominant gene, which in this case is g.
