There are differnt temperatures for differnt marine animals
In the natural world, limiting factors like the availability of food, water, shelter and space can change animal and plant populations. Other limiting factors, like competition for resources, predation and disease can also impact populations.
A bioindicator is a living organism that gives us an idea of the health of an ecosystem. Some organisms are very sensitive to pollution in their environment, so if pollutants are present, the organism may change its morphologyphysiology or behaviour, or it could even die. Hope that helped!
Answer:
(a) an aquaporin
Explanation:
An aquaporin is a water channel which forms a pore in the cell membrane and facilitates the movement of water. Aquaporin is an integral membrane protein (permanently attached to the membrane) that enables the in and out flow of the water. This channel also prevents the passage of ions and other solutes, so it cannot change the voltage. There are four types of aquaporins, and they are mostly found in the kidney with the function of water reabsorption.
Protein synthesis occurs in the cytoplasm, specifically in the ribosomes. Proteins that are meant to be excreted, such as in the pancreas, are produced in the rough endoplasmic reticulum which is a membrane studded with ribosomes. In organs that primarily function to produce and secrete proteins, there will be a larger rough endoplasmic reticulum with more ribosomes.
