Various environmental factors affect the marine ecosystem. These factors include light, oxygen levels, depth of ocean, salinity, density and pH. These factors are varies with depth in the ocean these factors will either support or limit the life processes of the marine organisms.
The region in the depth of ocean up to where light can penetrate is called photic zone which extends from few meters to 150 meters. Photosynthetic organisms such as phytoplankton and about 90% of all marine life lives in this zone.
In the deep ocean the pressure is very high so, organisms have to survive under extreme pressure. In the deep ocean organisms are small and with low metabolic rate.
Answer:When neurons communicate, an electrical impulse triggers the release of neurotransmitters from the axon into the synapse. The neurotransmitters cross the synapse and bind to special molecules on the other side, called receptors. Receptors are located on the dendrites. Receptors receive and process the message.
Explanation:
During the regeneration stage of the calvin cycle:
- The remaining glyceraldehyde three-phosphate (G3P) molecules are converted into ribulose biphosphate (RuBP), a five carbon sugar that is combined with CO2
- The reaction is speeded up by RuBP carboxylase (rubisco), an enzyme that catalyzes the combination of CO2 and RuBP
