Explain how considerations for human health help drive environmental policy decisions.
Answer:
Humans impact the environment, which can, in turn, have an effect on human health. Pollution is caused by human activity, and it also affects human health. Air pollution can cause respiratory problems and water pollution can lead to digestive problems. As human health is affected by these issues, concern increases and policies are enacted that address the causes of the issues. These policies do benefit the environment, but are, in part, brought about by concerns over human health.

O Both plant cells and animal cells have flexible plasma membranes.
O Plant cells have cell walls instead of plasma membranes.
O Plant cells have rigid plasma membranes.
The statement that is true about plasma membrane is that Animal cells have cell membranes instead of plasma membranes.
What is plasma membrane?The plasma membrane is the membrane found in all cells separate inside of the cell from outside environment. In bacterial and plant cells, a cell wall is attached to the plasma membrane from the outside surface .The plasma membrane consists of a lipid bilayer that is semipermeable. The plasma membrane help to transport of materials inside and outside the cell.
Therefore, plasma membrane is the membrane in cells that separate the outside from the inside of the cell.
