What is not the ultimate goal of science is to produce unchanging and absolute answers . Scientists would like to, however, understand patterns, give explanations for natural events, and even make predictions.
And it isn't really the case that they would like to produce unchanging answers.
Answer:
(E) present the two sides of the debate concerning the development of the vertebrate skeleton
Explanation:
In the paragraph, the author talks about two sides of view in the subject of vertebrates evolution. On one hand, he/she says that the first idea of vertebrates development is that the skeleton evolved as a defensive character and that many researchers rely on soft-bodied vertebrates to conclude it. On the other hand, he/she says that other researchers postulate that some vertebrate features (as paired eyes and adaptation in some muscles) could not have evolved if the first vertebrates were not depredators.
B) viral vaccine production
C) skin and tissue grafting
D) reproductive cloning
Correct answer: D) reproductive cloning
The cell technology that was possible by the micromanipulation tools is reproductive cloning. It is a form of artificial reproduction that uses the cloning technique.
It involves creating an animal that is genetically similar to a donor animal by the somatic cell nuclear transfer technique. In this cloning, the newly produced embryo is put back into the uterus where it can implant and develop further. There are two types of reproductive cloning by cleavage and cloning by the transfer of a cell nucleus into an enucleated ovum.
Hence, the correct answer would be option D.
b. Susan is right, James is the father
c. Susan is not the real mother of the child and an error was made in the nursery
d. It is impossible to make a decision based on the limited data available
