Answer:
A. Homeostasis allows organisms to regulate their temperature.
Explanation:
Homeostasis is a biological process through which the body of organisms try to maintain a relatively stable body conditions irrespective of the changes in the external environment.
<em>Homeostasis keeps body processes such as temperature, pressure, hydration, pH, etc. relatively stable. While some organisms maintain a stable body temperature by generating heat (endotherms), others do so by adjusting their body temperature to be in tune with that of the external environment (ectotherms). </em>
The correct option is A.
Answer:
- Erosion and deposition (shoreline retreat)
Explanation:
Sand moves along a shoreline through hydraulic and mechanical action (friction) of the waves. During this course, two phenomenons usually occur, i.e. erosion followed by deposition.
However, sometimes when the wave action is stronger, it leads to the coastal erosion or the shoreline retreat where a land part is permanently lost and the sand is moved with the waves forming beaches.
An example of this can be the exploitation of ivory. Elephants who provide people with ivory are being poached all the time because there's no way to get ivory other than this, and since the market is insatiable, the elephants are dying out and the poachers are profiting.
