<span>Research suggests that high dietary intake of omega-3 fatty acids by pregnant women may be related to higher iq levels among children. DHA, otherwise known as docosahexaenoic acid is found in omega-3 fatty acids and it helps with the development and function of a baby's brain. It improves learning ability and it can be found in foods such as breast milk, eggs or fatty fish.</span>
Answer:
artificial selection/selective breeding
Explanation:
The illustration is an example of <u>artificial selection.</u>
<em>By definition, </em><em>artificial selection</em><em> is the deliberate perpetuation of some traits in living organisms simply because the traits are desirable. The organisms are selected because of the traits and allowed to breed either naturally or otherwise in order to ensure that these traits appear or are even consolidated in the offspring of the breeding. </em>
The offspring from selective breeding are expected to combine the desirable traits of the two parents and thus, appear better than each of the parents.
D) differences between species and their ancestors
This is because of the adaptive mechanism and mutations the organisms have to respond to. <span>Adaptation processes occur to help species survive and thrive in the ecological balance of life. Structural adaptations are physical features of an organism that adapted through time. An example of this are the bills of a bird and the fur of bears that they generally need for their survival; birds for hunting, and bears to protect them from low climate areas.</span>
Considering the answers;
A. are still sibling species
B. shared a common ancestor more recently with each other than either did with the other two species
C.May merge into a single species if their hybrids remain fertile over the course of many generations.
D. A and B only
E. A, B, and C
The answer will be E.
If no other species can hybridize, then species W and Y are still sibling species, shared a common ancestor more recently with each other than either did with the other two species and also may merge into a single species if their hybrids remain fertile over the course of many generations.
Comparative anatomy is the study of the similarities and differences in the structures of different species. ... Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. These structures may or may not have the same function in the descendants.
