Answer:
Cells need oxygen and glucose.
Without oxygen, electron transport chain cannot take place and the cells cannot get the energy they need (since the cell uses oxygen to break down glucose which os what produces energy). When the cells cannot perform their function, they die.
Answer:
We can't see the options, how are we supposed to give you an answer without knowing anything?
<span>In order to move molecules in your kidneys or in your blood your body needs energy
ANSWER: ENERGY</span>
C6H12O6+6O2--->6CO2+6H2O
This is the equation for cellular resipiration this is how organisms use carbon-based molecules(glucose) and make water
Answer:
The temperature is kept at room temperature and mostly preferred to be constant, so that the temperature does't be a variable factor effecting the accuracy of experiment.
Temperature is kept constant to take it as a control factor, so that experimental results are not effected by such outside factors. Such control variables are important in experiments as they minimize the influences from outside.
