Answer:
plant cell
Explanation:
1.cell well-protected and provides structural support of cell
2.cell membrane regulates entries and entries of substances within the cell.
3.nucleus stores DNA
4.plastids they store starch help in photosynthesis
5.chloroplast pigment which protect cell
6.vacuole sustain turgid pressure against cell wall
7.mitochrondria provide energy to help break carbs
8.lysosome help with cellular waste disposal
When red blood cells are in a higher concentrated solution, water flows out of the cells faster than it comes in. This results in crenation or shrivelling of the cell.
Answer: the two tropics zones
Explanation:
Between the two tropics zones, which includes the equator, the Sun is directly overhead twice per year. Outside the tropic zones, whether to the south or north, the Sun is never directly overhead. Two other significant lines of latitude are the Arctic Circle (around the North Pole) and the Antarctic Circle (around the South Pole).
Answer:
c: the use of energy released from an exergonic reaction to drive an endergonic reaction.
Explanation:
<em>Energy coupling is a process involving two reactions whereby one of the reactions generate energy, and the generated energy is used to drive the other reaction. </em>
A reaction during which energy is generated is referred to as exergonic reaction while one in which energy is consumed is known as endergonic reaction. Hence, energy coupling can also be viewed as a process linking exergonic and endergonic reactions whereby the energy released in the former is used up by the latter.
A good example is illustrated by the light dependent and light independent reactions of photosynthesis during which the ATP and NADPH produced during the light dependent reaction is used to fix carbon dioxide in the light independent reaction.
<em>The correct answer is C.</em>
They return nutrients from waste or dead organisms back into the ecosystem to be recycled.
