Explanation:
All of the body processes, like digestion, pumping blood, breathing, are powered by cells converting the stored chemical energy into work and heat, in a process called respiration. ... Inside the muscle cells of the human (or any animal), the chemical energy is transformed (changed) into mechanical work and heat.
Answer:
a) A cell will shrink when the concentration of electrolytes is greater inside the cell than outside the cell. FALSE
Explanation:
The regulation of cell fluid is caused by molecules called as Electrolytes. The higher concentration of these electrolytes outside the cells or lower concentration inside the cells will suck water outside the cells. Water is pumped to the area where the concentration of electrolytes is high. It is also clears from the Option d) that water follows the movement of electrolytes so it means that water will move to out if the concentration of electrolytes outside the cells is high which will cause shrinkage of cell organelles.
The correct answer is: d) begins later in life
Eggs or female reproductive cells are formed well before birth in a huge number (primordial oocytes). But, the number of oocyte decreases after birth constantly (there are 2 million oocytes at birth and 40,000 of them in puberty). At menopause, no egg cells are left.
On the other hand, the first sperms are formed only from puberty, but the production of those cells never stops.
Answer:
Our water resources face a host of serious threats, all of which are caused primarily by human activity. They include sedimentation, pollution, climate change, deforestation, landscape changes, and urban growth.
Speed. This is more of a physics question.
