Explanation:
1. Light dependent
2. Light independent (Calvin-Benson Cycle)
Solution:
The ecosystem boundary of a drainage basin can be defined by the mountains, hills and valleys that determine where the water flows.
Since the Ecosystem is define as all the organisms and their physical and chemical environment within a specific area where energy and matter influence the distribution and abundance of organisms present.
Thus the right answer is mountains, hills and valleys that determine where the water flows.
Answer:
The presence of proton pumps in the lysosome membrane that allows the organelle to maintain higher concentrations of protons.
Explanation:
Lysosomes are known as a membrane-bound cell organelle that is present in many animal cells. They are spherical type vesicles in structure. Lysosomes contain hydrolytic enzymes these enzymes help in the break down of different kinds of biomolecules.
The lysosomal membrane helps to protect the cytosol, and rest of the cells, from the degradative enzymes which are present in the lysosome. They have the ability to maintains their pH by pumping in H+ ions (protons) from the cytosol across the membrane with the help of chloride ion channels and proton pumps.
Fish are cold-blooded or poikilothermic, meaning that their body temperatures vary with the surrounding temperature. During the cold of winter fish become less active. They find little pockets out of the way of fast moving water where they can stay still and conserve energy.
