c. horse and cow
d. sea lion and dolphin

Answers

Answer 1
Answer:

The following pairs that are most closely related are horse and cow, Thus, option "C" is correct.

How can you prove that two species are closely related?

Species may communicate similar biological characteristics because the characteristic was present in a shared ancestor (homologous structures).

DNA and the genetic code reminisce the shared ancestry of life. DNA comparisons can show how related species are.

Thus, option "C" is correct.

The process in which a gene from one organism is inserted into the DNA of another organism

Answers

The procedure of inserting a gene from one organism into another is ;

  • Recombinant DNA technology

Recombinant DNA technology is a part of genetic engineering whereby the DNA molecule from different species are fused together ( I.e. DNA  molecule is taken from a donor and inserted into the DNA of the host ).  

The process is carried out in order to produce a desired genetic combinations/trait in the offspring produced. which will be beneficial to science and other fields as required ( mostly agriculture and medicine ).

Hence we can conclude that the process is called Recombinant DNA technology.
