What ultimately happens to the light energy captured during photosynthesis?
Degger [83]

Answer:

The correct answer is- It is used to produce glucose molecule

Explanation:

Photosynthesis is a process in which light energy is captured by chlorophyll which is then used to convert carbon dioxide and water into glucose. Oxygen is also produced as a by-product in this process.

The light energy is used to split water into oxygen, hydrogen ions and release electrons from it. The electrons pass through many electron carriers through photosystem II and I and ultimately reduce NADH+ to NADPH which is used in the Calvin cycle to produce glucose.

Therefore glucose is produced by the help of light energy captured during photosynthesis.

What type of ions carry the impulse across the synapse from one neuron to the next ?
grandymaker [24]

It's the sodium ion.

When a neural impulse is fired in both neurons, it is always cause by an excited electron in one neuron moving to the other neuron to destabilize the balance of ions trying to keep them at equilibrium. This action either depolarizes or hyper-polarizes the membrane. If it does, then sodium ions--the key deficient ones--can flow into that region of low charge and maintain that state of low charge, keeping the cell membrane stable.

More solar energy reaches the equatorial regions than the polar regions because the equatorial regions
crimeas [40]


The answer is that the equatorial regions receive sun rays closest to the vertical (direct rays) because of their position relative to the equator where the tilting of the earth only mildly affects the climate. The climate along the equator  changes very little through out the year and has summer like conditions for  most of the year.

However the other regions may receive direct sun rays but for far more limited periods.  In the months of July and August (summer months), the northern hemisphere is tilted towards the sun and receives the most  direct  rays. The opposite occurs in December and January when it is tilted away from the sun and thus winter sets in, whereas the southern hemisphere is at this time tilted toward the sun and receives the most direct sun rays.
