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.
We need options :) but stem cells are a amazing type of cells that are able to develop into many different types of cells <span>First, they are unspecialized cells capable of renewing themselves through </span>cell division<span>, sometimes after long periods of inactivity. Second, under certain physiologic or experimental conditions, they can be induced to become tissue- or organ-specific cells with special functions. In some organs, such as the gut and bone marrow, stem cells regularly divide to repair and replace worn out or damaged tissues. In other organs, however, such as the pancreas and the heart, stem cells only divide under special conditions.</span>
4 mps increase in 10 seconds = 2 mps increase in 5 seconds = .4meters/2sec
The offspring will be genetically identical to the parent because vegetative reproduction is a form of asexual reproduction. Therefore, there is only one parent and the offspring is identical to the parent.
