Answer:
colder, rich in nutrients
Explanation:
fertilizes surface waters meaning they have high biological productivity
<span>Bacterial genome is prone to mutational changes due to its simple nature and less efficient DNA repair mechanisms compared to humans, thus it has more chances of obtaining new genetic traits.</span>
<span> In </span>animal cells centrioles<span> organise the pericentriolar material to produce microtubules including mitotic spindle fibres.</span><span />
Yes, It seems that evolution has occurred in this area.
Explanation:
Evolution refers to a phenomena in which new traits or alleles that favor a better survival of organisms in a given environment, become fixed in the population.
Evolution is characterized by appearance of new characters and change in allele frequencies.
In the given situation we find that the frequency of the recessive allele in the population has changed over time and the percentage has become fixed.
So, we can say that evolution has occurred in the robin population
