Answer:
If this is a yes or no question, I'm gonna say no... Please let me know if I am wrong.
Answer:
Presence or absence of cilia/stinging cells.
Numbers.
Retractability.
Number of cells.
Explanation:
Apart from size difference, tentacles in Cnidaria and Bryozoa differs such that:
- <em>The tentacles in Cnidaria have no cilia surrounding them while those of Bryozoa are ciliated. Instead of cilia, the tentacles in Cnidaria have stinging cells.</em>
- <em>Tentacles in Cnidaria are fixed in number while the number may vary in Bryozoa.</em>
- <em>Tentacles in Cnidaria are often retractable while retractability is not possible in Bryozoa.</em>
- <em>Cnidaria tentacles are made up of multiple cells while those of Bryozoa are made up of single cells.</em>
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.
