Explanation:
DNA sequencing is a biochemical process used for determining the order of the nucleotide bases, adenine, guanine, cytosine, and thymine, in any DNA molecule. By comparing the DNA sequence of two organisms, scientists can see if the organisms are related or not, as well as how closely they are related.
Answer:
· Nitrogen fixation
· Nitrification
· Assimilation
· Ammonification
· Denitrification
Explanation:
Nitrogen fixation is the process where nitrogen is converting into ammonium.
Nitrification is the process of ammonium oxidation into nitrate.
Assimilation is the process where animals and plants receive NO3. Plants are using this nitrate for proteins and acids.
Ammonification is the process where the nitrate that is contained in plants and animals is recycled after their death.
Denitrification is e the last process in this cycle and during this process nitrate is converting to gases.
Answer: E. When one contracts, the other relaxes and this allows the bones to move; triceps and biceps.
Explanation:
Antagonistic action occurs between the two pairs of muscles. In this action one muscle while contracts other muscle relaxes. The example of antagonistic pair is of biceps and triceps. The triceps remain in the relax phase while the biceps contracts so as to lift the arm.
The answer is B. Muscle Fiber
