The correct answer is C.
In the aquarium, the water plants would provide the O2 molecules necessary for the snail's metabolism and the snail would release the CO2 molecules that are a byproduct of his metabolism into the container. The CO2 would later be used by plants to make sugar in the process of photosynthesis, releasing more O2 and the cycle of two gases would be completed.
Answer:
Scientists have determined that humans are disrupting the nitrogen cycle by altering the amount of nitrogen that is stored in the biosphere. The chief culprit is fossil fuel combustion, which releases nitric oxides into the air that combine with other elements to form smog and acid rain.
Explanation:
Depending upon the type of energy detected by receptors , they can classified into many groups but you need for so I'm going to write here only four with their functions
1. Thermoreceptors: they detect changes in temperature
2. Chemoreceptors: they detect chemicals dissolved in body fluid medium surrounding them.
3. Mechanoreceptors: they detect sound , motion , position in relation to gravity.
4. Photoreceptors: they detect visible and ultra violet light!
Hope so it would help!
Answer:
Voltage-gated membrane channels open, and Ca+2 enters the cytoplasm, increasing intracellular calcium
Explanation:
The neurotransmitters in the neurons are stored in the synaptic vesicles in the synaptic knob present at the axon terminal.
The neurotransmitters are released when the action potential reaches the axon terminal and opens up the voltage-gated calcium channels. The calcium channels allow the entry of the calcium from the synapses and this causes the release of the synaptic vesicles which fuses with the cell membrane. This fusion releases the neurotransmitter in the synapse.
