<span>How are the dark reactions that occur in plants dependent on the light reactions?
a.The chemical energy used in the dark reactions is produced in the light reactions.
Photosynthesis is divided into two parts.
1) Light - dependent reaction
2) Light - independent reaction
Light dependent reaction absorb energy from the sun to produce ATP and NADPH, these energies are used in the light-independent reaction. The ATP provides the energy, while the NADPH provides the electrons required to fix the carbon dioxide into carbohydrates.

Molecules that cannot cross the membrane bind to receptors in the membrane. When the signal binds to a receptor changes it's shape. Other Molecules inside the cell respond to the chainging shape of the receptor.
<span>When a quarter of the population is killed by disease, it will affect the survivors in many ways. They will be physically weak from disease, emotionally scarred, and left without people they love, as well as people who filled important roles in society. There will be a time of mourning, and it will take time to recover. They will have to learn to accept a new normal.</span>
2. In cell biology, MITOSIS is part of the cell cycle in which chromosomes in a cell nucleus are separated into two identical sets of chromosomes, and each set ends up in its own nucleus.
3.In females, MEIOSIS occurs in cells known as oogonia (singular : oogonium). Each oogonium that initiates MEIOSIS divides twice, unequally in each case. The first division results in a small "first polar body" and a much larger daughter cell. that's all I know sorry :)
