Answer:
More sunlight but less space.
Explanation:
The fallen tree would have let in more sunlight as it was blocking sunlight from getting in most of the time. Since the tree fell more sunlight will be able to get in. The only problem would the fact that there will be less space depending on the size of the tree and how it fell over.
Fossil fuels are considered a nonrenewable energy source because once fossil fuels are used, they are gone. So, the correct option is A.
<h3>What do you mean by Nonrenewable energy?</h3>
Nonrenewable energy may be defined as that energy that once consumed can not be replenished for millions of years.
Fossil fuels are examples of nonrenewable energy resources. The formation of fossil fuels may take over millions of years. This fuel is made naturally by the decomposition of dead and decayed organic living matter.
Therefore, the correct option for this question is A.

Explanation:
Answer:
The membrane potential of a nerve cell will depolarize if there is an increase in the positive ions inside the cell.
Explanation:
When nerves are in resting potential it is -70mV. In this stage interior of the cell is negatively charged and outside is more positive. When depolarization occurs the inside cell becomes positive.
This is due to the rush of sodium ions into the cell by voltage-gated channels. Now the inside charge is more positive and the chloride ions move out of the cell. Thus outside becomes more negative.
After some time of depolarization stage, potassium ions move out of the cell making the nerve cell again negative. Now the depolarized stage becomes repolarized by the entry of potassium ions.
During depolarization, the potential of the cell is -55mV. When repolarization occurs, it is again -70mV. But the potassium channels are open and some of the potassium ions move out of the cell making the inside environment more negative. This is known as hyperpolarization condition.
This hyperpolarization remains for a short period where action potential can't occur. This period is called the refractory period. Again potassium ions enter into the cell. This results in the resting potential of the neuron again.
• Biochemical processes give rise to the complexity of life
• Much of biochemistry deals with the structures and functions of biological macromolecules.
• Such as proteins nucleic acids, carbohydrates and lipids, which provide the structure of cells and perform many functions associated with life
