<u>Answer :-</u> <em>Option 2</em> 90 mm is correct.
<u>Explanation :-</u>
- In the given diagram, we consider the starting point of measurement the value where the mouth of the earthworm is pointed i.e 1.5 cm.
- So if we count from 1.5 cm that is the start point and then we see the end point i.e 10.5 cm we get,
10.5 - 1.5 = 9.0 cm
So the length of the earthworm is 9.0 cm as seen from the scale.
- Now to convert cm into mm, we need to know that:
1 cm = 10 mm
Thus, to convert 9.0 cm to mm
we need to multiply 9 by 10
9 X 10 = 90
So the answer is 90 mm.
Memory B cells are the type of B cells which are formed after the primary infection.
These are important as they help in producing the more intense and accelerated immune response during secondary infection or when the same antigen or infectious agent enters the body.
They do so by producing the polyclonal response, that is, the same epitope is attacked by multiple copies of B cells.

Answer:
one gene - one enzyme.
Explanation:
The Garrod's explain the hypothesis one gene enzyme and one enzyme. According to this hypothesis, the single gene codes for the single enzyme that plays an important role in the body metabolism.
The Garrod's hypothesis was experimentally performed by the George W. Beadle and Edward L. Tatum. They performed the biochemical studies and genetic tests on Neurospora to explain the one gene one enzyme hypothesis.
Thus, the correct answer is option (a).
