According to embryology, why do fish and birds have common ancestor?

Biology
1 answer:
Cloud [144]3 years ago
8 0

Answer:

Both fish and bird embryos possess gill slits and gill arches.

Explanation:

Embryology -- the study of embryos -- is a fundamental area that is correlated to evolution. Together, <u>they have provided evidence that we all evolved from a common ancestor.</u>

This area of study has showed that embryos that look completely different as adults share many similarities during their development. This is the case of numerous species, such as humans and birds and fish and birds.

<u>Both fish and bird embryos possess gill slits and gill arches</u>. However, <u>only fish possess them as adults. Gill slits develop into gill individual openings and gill arches will eventually support these gills. In contrast, adult birds do not possess gills, they are only present during their development.</u> This provides significant insight into the previously mentioned common ancestor theory.

Resource partitioning results in: a move from the realized niche to the fundamental niche for both species. individuals of each
bazaltina [42]

Answer:

a move from the fundamental niche to the realized niche for both species.

Explanation:

The niche of an organism is the functional role of the organism in the community or the ecosystem as a whole. This include the environment an organism lives and all the jobs it does in it.

Fundamental niche refers to all the possible functional roles of an organism in an ecosystem while realized niche refers to the specific roles the organism is limited to as a result of resource limitation, competition or other factors.

Resource partitioning involves the division of limited resources among organisms so as to avoid competition within the niche.

<em>Hence, resource partitioning causes a move from the fundamental niche of an organism to the realized  niche of that organism. </em>

If a population with two alleles is at Hardy-Weinberg equilibrium ad the frequency of one allele is 0.7, what is the heterozygot
Vinil7 [7]

Answer:

B. 0.42

Explanation:

Since the two alleles are at Hardy-Weinberg equilibrium, the sum of the frequency of two alleles will be one. If the frequency of a dominant allele is "p" and that of the recessive allele is "q", then p+q=1

According to the given information, the frequency of one allele in the population is= 0.7

This means that the frequency of the other allele would be= 1-0.7 = 0.3

Frequency of heterozygote in the population =2pq = 2 x 0.7 x 0.3 = 0.42
