The size changes in horses through time is an example of Cope's Rule
The propensity for organisms in evolutionary lineages to become larger over time is known as Cope's Rule. Although the idea is covered in great length in numerous textbooks, it is rarely illustrated. There are numerous hypotheses on the advantages of having a large body size, but none have been objectively proven.
According to Cope's rule, evolution typically results in a lineage of populations growing larger over the course of geological time. In the fossil record, there are numerous examples of evolutionary processes that lead to an increase in body size. For instance, the size of the Eocene horses' forebears was comparable to that of a dog.

Answer:
24%
Explanation:
The given genetic trait is homozygous recessive and the frequency of homozygous recessive genotypes in the population is 2%.
Therefore, frequency of homozygous recessive genotypes (q2) = 2% = 0.02
Frequency of homozygous recessive allele (q) = square root of 0.02 = 0.141
Since p+q =1 (here, p = frequency of dominant allele).
So, p= 1-q = 1-0.141 = 0.859
The frequency of heterozygous carrier genotypes in the population = 2pq = 2 x 0.141 x 0.859 = 0.24 or 24%
Answer:
In liver development, most Mono hepatocytes undergo the conventional cell cycle to replicate. However, some of them undergo mitosis without cytokinesis to produce Bi hepatocytes.

Answer:
The population of the original herd would decrease and the new one would increase.
Explanation:
<em>Impetigo is the most common bacterial infection in children. This acute, highly contagious infection of the superficial layers of the epidermis is primarily caused by streptococcus oncogenes or staphylococcus aureus</em>
