Answer:
The answer of ist question FADH2,NADH 2nd question O2 3rd question NAD+,FAD,H2O,ATP.
Explanation:
Ist answer
During electron transport chain electrons are donated by reduced coenzymes such as NADH and FADH2.
2nd answer
During electron transport chain oxygen or O2 act as terminal electron acceptor which accepts and then undergo reduction to generate H2O.
3rd answer
The final products of electron transport chain and oxidative phosphorylation are NAD+, FAD,H2O and ATP.
Answer:
- Dependent variable: number of cells that are in one of the phases of mitosis
Explanation:
In an experiment, the independent variable is the variable that is not changed by the other variables that are being measured during the experiment (in this case, the independent variable is represented by the distances from the root cap). On the other hand, the dependent variable is the variable that is being measured/tested during the experimental procedure and, therefore, is 'dependent' on the independent variable. In consequence, in an experiment, the dependent variable is expected to change as a result of the manipulation of the independent variable.
C. The lungs can better exchange oxygen
Answer:
Breathing heavily after you have finished running a race is your body way of repaying an oxygen debt.
Explanation:
Any kind of exercise that is performed makes our muscles work harder. As a result, more calories get burned by these muscles. To burn the extra calories, more supply of oxygen is required by the muscles. As you exercise harder, the breathing increases and become heavier to bring more oxygen to the lungs. From the lungs, the oxygen is carried to the muscles which are burning more calories.
You breathe heavily at the end of a race to get enough supply of oxygen.
Over time, those who cannot live through the temperature differences/have undesirable qualities will die off. Overtime, those with desirable qualities are left and they will continue the population.
