<span>The question is which organelle break down sugar molecules that supply energy to the cell. The answer is mitochondria. Mitochondria is referred to as the power house of the cell because it handles cellular respiration of the cell, which involves breaking down of sugar molecules to form energy in form of ATP.</span>
The sun energy reaches earth through radiation.
Answer:
VERY SLOWLY.
Explanation:
When he air we breathe is readily saturated with water, the sweat on your skin can't evaporate. This state of the body will leave you feeling sticky and warm, in as much as the body tries to cool down. High humidity in hot weather will only worsen your discomfort, as the moisture simply sits on your skin unable to evaporate.
In the effort to cool, our bodies must work even harder. This leaves our body to excessive sweating, depth of blood circulation, increased rate and also increased respiration.
Answer:
The mechanism by which cells regulate their ability to respond to extracellular messengers is known as receptor signalling.
Explanation:
Cells senses an environment and communicate which each other through ligand-induced activation of signalling receptors at the cell surface. Signalling receptors enter the endocytic pathway and are sorts into various compartments. Endocytosis regulates cell signalling by controlling the number of receptors available for activation in plasma membrane and activation of receptors or downstream effectors often stimulate receptor endocytosis.
