Answer:
diffusion through a selectively permeable membrane
Explanation:
The cell membrane selectively allows certain substances to enter or leave a cell . This implies that cell membranes are selectively permeable; they allow some substances to pass through, but not others.
Direct transport of materials across the cell membrane is often passive. Passive transport does not require energy to occur. Passive transport is the movement of substances from a region of higher concentration to a region of lower concentration. A concentration gradient is always required.
The diffusion through a selectively permeable membrane is an example of passive transport.
The iodine moves into the dialysis tube across the semi permeable cell membrane from a region of higher concentration to a region of lower concentration in response to a concentration gradient.
The answer is serotonin. Serotonin is a significant chemical neurotransmitter in the human body. Serotonin that is used in the brain must be made within it. It is believed that serotonin can touch mood and social performance, hunger and ingestion, slumber, reminiscence and sensual desire and purpose.
This varieation can be justified because since they had different variations they probably had different niches which led them to evolve differently,this will help because the two species will have no competition
White Blood cells Because they are produced in your body and they are constantly used more than they are replaced
Answer:
The ecosystem will be destabilized as abiotic resources like available space are reduced.
Key species found on the barrier island will move to a new habitat.
Explanation:
Due to living of humans on the barrier Island with adversely affected the organisms present on that Island because the loss of habitat occur due to living of humans and the important species migrated to other habitats where no humans are present. So this action greatly change the environment of barrier Island and the ecosystem will be destabilized.
