We know, DNA is the main molecule by which scientists can learn about evolution by comparing the DNA structure between two different organisms. 
But, in addition to DNA (which is most helpful & important) still, there are 3 molecules that can help us, They are:

1) RNA : - It is found in cytoplasm, as DNA transfers it's codes into RNA during Central dogma, it can help us in evolution studies.

2) Proteins: - Another helpful feature, into which RNA transforms in Central Dogma.

3) Pseudogenes: - It is also known as "Non-coding DNA" It is extra <span>DNA in a genome that do not get transcribed into RNA to synthesize proteins. They can also help us in Evolutionary studies.

Hope this helps!</span>

marissa [1.9K]

Answer:

The correct answer is A) Biochemical test

Explanation:

In microbiology biochemical test is used to examine the metabolic activities performed by bacteria to identify that microorganism. So in biochemical test enzymatic reaction of cell is usually investigated because there is difference in enzymatic activity of different species of bacteria.

For example, catalase test that is used to differentiate between catalase-positive and catalase-negative bacteria is an example of biochemical test. Catalase-positive bacteria have the catalase enzyme that breaks hydrogen peroxide into water and oxygen which is confirmed by bubbles that appear on glass slide.

Catalase negative bacteria do not form bubbles when they are put in hydrogen peroxide which shows that they lack catalase enzyme. So the right answer is A.

What is turgor pressure and why is it important
saw5 [17]
Turgor pressure is the water pressure inside plant cells. This is maintained by osmosis, which is the movement of water across a <span>different permeable membrane from a place where water concentration is higher to one where the concentration is lower.

Turgor pressure is important because it is what helps a plant stand upright and maintain the plant's structure.</span>
