Answer:

In the light-independent reactions, the plant starts with carbon dioxide and ends up with glyceraldehyde-3-phosphate (G3P). It uses ATP and NADPH from the light-dependent reactions as energy sources  

Explanation:

<em>Step 1:</em> CO₂ adds to ribulose biphosphate (RBP) to form a six-carbon sugar that immediately decomposes into two molecules of 3-phosphopglycerate (3-PGA).

CO₂ + RBP ⟶ 2 3-PGA

<em>Step 2</em>. A phosphate group adds to the 3-PGA to form 1,3-biphosphoglycerate (1,3-BPG).

3-PGA + ATP ⟶ 1,3-BPG + ADP

<em>Step 3</em>. NADPH reduces the 1,3-BPG to G3P

1,3-BPG + NADPH ⟶ G3P + NADP⁺

Most of the G3P is regenerated into RBP, but some leaves the cycle to become glucose.

Explain how the law of conservation of energy is applied to the generation of electricity from fossil fuels.
sweet [91]

Explanation:

The law of conservation in generation of electricity from fossil fuels;

 Fossil fuels are derived from the remains of plants and animals.

These fuels stores and preserves chemical energy which have produced through their activities which originates from the sun as form of solar energy.

The chemical energy is obtained for used as fossil fuels.

As fuels, they combine with oxygen in power generating plant to produce heat energy. The combustion process transforms chemical energy to heat energy.

The heat energy is used to heat boilers of water to produce steam. Heat energy is expressed as thermal kinetic energy which are converted to mechanical energy to drive turbines. The turbine is connected to a generator where electricity is produced.

This totally agrees with the law of conservation of energy.

The law states that "energy is neither created nor destroyed but transformed from one form to another"

Chemical energy - heat energy - mechanical energy - electrical energy

The hypothalamus acts as both a neural and a(n) ________ organ.
Artemon [7]
Hypothalamus is a part of the brain that links the nervous system to the endocrine system via the pituitary gland. It helps maintain the internal environment constant by regulating major processes in the body such as the heart rate and the body temperature. It is therefore, both a neural and endocrine organ.
