Answer:
Due to absorption of more water.
Explanation:
A Cotton shirt takes more time to dry as compared to a synthetic shirt due to absorption of more water by the cotton fiber as compare to other fiber. Cotton absorbs much more water than other synthetic fibers, and attached to the molecules of cotton for longer period of time which means cotton fibers take more time to dry as compared to synthetic fiber which absorb little amount of water and loosely attached to the molecules of fiber.
Answer:
Input is oxygen and output is carbondioxide or the movement.
Explanation:
These two systems i. e. scuba diver and scuba gear interacting with each other by giving oxygen to the individual and remove carbondioxide gas from the diver. The input of this system is oxygen that is required by the diver while the output is the carbondioxide gas produced by the diver or the movement of the diver. This scuba gear is responsible for the removal of carbondioxide gas from the system. This scuba gear enable us to stay in deep water for 60 minutes.
Answer:
3. multicellular
Explanation:
not a bacteria, because, well, its an insect, its not a prokaryote, because an insect has more than one cell, and prokaryotes are unicellular, and its not abiotic because an insect is a living thing
sorry, not sure about no. 2
The subcellular structures of neuron that forms the basis for transmission of nerve impulses are the synaptic vesicles.
What are the steps in impulse transmission between neurons?
- The action potential or nerve impulse reaches the <u>axon</u> of neuron and depolarises the membrane.
- Voltage gated Calcium channels open .
- Arrival of action potential causes the synaptic vesicle to attach to presynaptic membrane.
- Calcium influx triggers release of neurotransmitter.
- This neurotransmitters bind to postsynaptic membrane and new impulses are created.
Synaptic vesicle under resting condition:
- The neurotransmitter molecules are stored in synaptic vesicles.
- If the neurotransmitter leak from the vesicles, they are destroyed by enzymes.
- During resting condition, they are placed randomly.
- When an impulse reaches the axon, vesicles are arranged in the presynaptic membrane.
Thus from the above we can conclude that, synaptic vesicles are the subcellular structures in transmission of nerve impulses and , under resting condition they are placed randomly.
