Answer:
The correct statement is - option B.
Explanation:
Unmyelinated axons are the axon that lacks the covering of scwann cells that form the myelin sheath which helps in the transfer or transmit the signals faster and more effectively in neurons. It acts as the insulating layer.
In absence of the myelin sheath, the action potential found everywhere along the length of the axon which leads to slow propagation than in myelinated axons.
Thus, the correct answer is - option B.
Answer:
DNA is made up of deoxyribose sugar while mRNA is made up of ribose sugar.
DNA has thymine as one of the two pyrimidines while mRNA has uracil as its pyrimidines base.
DNA is present in the nucleus while mRNA diffuses into the cytoplasm after synthesis.

Answer:
Focal length is 6.67 cm.
Explanation:
Object distance, u, from the lens = 10 cm
Image distance, v, to the lens = 10 cm + 10 cm
= 20 cm
Apply the lens formula to determine the focal length, f, of the lens.
= +
= +
=
=
Find the inverse of both sides, so that;
f =
= 6.67
f = 6.67 cm
The focal length of the lens is 6.67 cm.
It transfers from being to being, from the sun, where it starts, to every other being after.
Hope this helped.
