D. ghost fishing
Explanation:
The nets are also called "ghost nets" being left behind or lost in the ocean by fishermen.
Also, never leave nets in the water. Our Earth needs healing.
A Protein Pump :- Protein pumps use energy from hydrolysis of ATP to move ions or large molecules across cell membrane.
Purpose of a Protein Pump :- In a Protein Pump the proteins help in active transport of molecules. Example, Membrane proteins are very specific and help in active transport. These proteins are positioned to cross the membrane so one part on the inside of the cell and one part is on the outside of the cell. Only when they cross the bilayer(cell membrane) they are able to move molecules and ions in and out of the cell.
Need for a Protein pump to work :- In active transport, A protein pump changes its shape when allows movement of molecules and therefore requires energy in the form of ATP. They use the energy of ATP hydrolysis to move ions or small molecules across a membrane.
This is yet under the rigorous study of scientist and there was two hypothesis considered between the relationship of thick mucus and chloride ions. However, in cystic fibrosis patients, one thing is common, there is an imbalance of chloride ions in epithelial cells. The imbalance of chloride postulated are the high concentration of chloride inside or outside the epithelial cells. Overall, there is a disruption of chloride ion flow which also disrupts the flow of water in cellular osmosis.
Water travels upwards through xylem, a type of plant vascular tissue. Vascular Tissue. Transport ... Both xylem and phloem are made of elongated cells placed end-to-end like sections of a pipe.
