Shivering occurs when the core temperature of the body begins to decrease which would threaten normal body function. Shivering is a response by the body to bring back temperature back to homeostasis. Trembling is the continual involuntary contraction of muscles. Muscle activity releases heat that warms up the body. This is the reason why we sweat during physical activities as the body sheds excess heat generated by the muscles in order to maintain the homeostatic body temperatures of 37 degrees centigrade.
Answer:
starch molecules are too large to diffuse through the membrane.
Explanation:
Answer:
<em>It is the outermost covering of a cell that separates the contents of the cell from its external environment. </em>
<em />
<em>It only allows the entry and exit of some materials. It also prevents the movement of some. Therefore, it is also called a selectively permeable membrane.</em>
<em />
<em>Some substances like carbon dioxide and oxygen can move across the cell membrane due to the process known as diffusion.</em>
<em />
<em>Water also obeys the laws of diffusion. The movement of water molecules through a selectively permeable membrane is called osmosis.</em>
