Answer:
The technique is known as "staining"
Explanation:
Staining is a technique used to enhance the color contrast of the microscopic samples when observed in the microscope especially in the microbiological samples.
In the given question, when the staining technique is used to identify the sample then staining procedure is followed in a process where the samples can be identified on the basis of the color contrast which is in the case of gram staining.
The gram staining is used to identify the bacteria on the basis of color as the bacteria which appear blue in color are called gram-positive and the bacteria which appear red in color are gram-negative bacteria.
Thus, staining is the correct answer.
True
You can’t skip any step; you need to do each step in order.
Answer: NO BLOODY PICTURE. I never get the picture, diagram whatever, so why do I get the question?

Explanation:
This graceful antelope is known for its long, spiral horns, which males use to challenge each other in tests of strength. Older impala males stake out mating territories and herd groups of females that they jealously guard against any rivals. During this exhausting mating period, the male must fight off challengers, herd his females, and mate with them. Unsuccessful bids to take over a male's territory usually end with the loser retreating to join a bachelor herd.
Females typically give birth about seven months after they mate, usually to a single impala. Both mother and baby join a herd of females and offspring within a few days.
Answer:
The nitrogenous bases of DNA are categorized into two types depending on their structure: Pyrimidines which contains a six-membered ring-like cytosine, thymine and uracil and purines which contains six members rings attached to a five-membered ring like in guanine and adenine.
The base pairing in DNA double-helical structure always takes place between purine and pyrimidines as:
1. The pairing between the purines and pyrimidines results in uniform diameter between two strands which provides stability to the ladder-like the structure of DNA.
2. The chemical side groups attached to the nitrogenous bases allow the formation of hydrogen bonds between purine and pyrimidines.
Therefore, A always binds T through two hydrogen bonds and G always bind C through three hydrogen bonds.
