While mercury occurs naturally in the environment, human activities that increase the number of  elements in the ecosystems. Examples of such activities include;

  1. Smelting and incineration of waste
  2. Coal-fired electricity generation

When the mercury settles in lakes and oceans and consumed by fish, the toxin get to the fish tissues. As the fishes are predated on, there occurs a phenomenon called bioaccumulation in the high animals in the food chain.

How does the movement of materials across the cell membrane relate to an<br> organism’s survival?
ioda

I believe it relates because as we know the cell membrane is permeable meaning that allows oxygen, carbohydrates, food to enter the cell but it doesn't allow the entrance of large molecules that harm the cells.

After all the movement around it, matters because for example without food the mitochondria won't be able to create the energy and then with that energy, the nucleus to use it to complete the main the activities of the cell.

Hopefully this what you meant when you asked the question. Have a nice day/evening

Novay_Z [31]

Explanation:

Capillaries, the littlest and generally various of the veins, structure the association between the vessels that divert blood from the heart (supply routes) and the vessels that return blood to the heart (veins). The essential capacity of capillaries is the trading of materials between the blood and tissue cells.  

Blood vessels a cylindrical organization all through the body that permits blood to spill out of the heart to each body cell and afterward back to the heart. The three kinds of veins are corridors, vessels, and veins. Each vein comprises of a layered divider encompassing a focal blood-containing space, or lumen.

9966 [12]

Answer:

4. Membrane and proteins secreted by the cell

Explanation:

Endoplasmic reticulum (ER) is one of the organelle that makes up the endomembrane system of eukaryotes. The ER is of two types viz: rough endoplasmic reticulum (RER) and smooth endoplasmic reticulum (SER).

The RER is called "rough" because of the ribosome organelles that are attached to its surface. The attachment of this ribosomes (site of protein synthesis) also defines its function. The RER is principally involved in the production of protein. Hence, the Rough Endoplasmic Reticulum functions mainly in the production of membrane and proteins secreted by the cell.
