1.Beak for catching prey
2.Wings to fly away from danger
3. Ability to balance
Answer: 1, 3, 5, 2, 6, 4
Explanation:
The sympathetic nervous system stimulates many parts of the body for action during times of danger.
This signalling starts when the postganglionic neuron depolarizes, and postganglionic neuron releases acetylcholine, then the acetylcholine binds to nicotinic receptor in order to transmit impulse, and further the acetylcholine binds to sweat gland’s muscarinic receptor to disrupt or inactivate the action of acetylcholine. Finally, the neuron releases acetylcholine, and the neuron exits lumbar segment of spinal cord.
The danger has now been fully interpreted.
Stem cells of the animals are the most similar to the meristematic cells of the plant.
<u>Explanation:</u>
- Meristematic cells are the most important cells for the plant which give rise to the various tissues and plant organs. These meristematic cells are capable to undergo cell division and they are called totipotent.
- The stem cells of animals and humans are capable of doing the function by replacing the new cells for growth and development.
- The difference among these two tissues is that meristematic is capable to produce total organs whereas stem cells are capable to produce only specific tissues.
