Photosynthesis occurs in two stages. In the first phase, light-dependent reactions or photosynthetic reactions (also called the Light reactions) capture the energy of light and use it to make high-energy molecules. During the second phase, the light-independent reactions (also called the Calvin-Benson Cycle, and formerly known as the Dark Reactions) use the high-energy molecules to capture carbon dioxide (CO2) and make the precursors of carbohydrates.
The process only takes a couple seconds to take place but both of the stages require the molecules to have a certain energy level.
When the air temperature is low, fewer molecules have the proper energy level and so only a small amount of photosynthesis takes place. Warm temperatures allow a lot more molecular conversions.

Answer:
How does gel electrophoresis separate DNA? :
The technique of gel electrophoresis is used to separate DNA fragments based on their size. DNA samples are placed into wells (indentations) at one end of a gel and pulled through using an electric current. Negatively charged DNA pieces gravitate toward the positive electrode.
How is genetic engineering used to treat genetic diseases? :
Gene therapy aims to rectify genetic abnormalities and thereby prevent or treat hereditary disorders by modifying genes. Genetic engineering tries to tweak genes to improve an organism's capabilities beyond what is normal.

Answer:
Hypotahlamus
Explanation:
Hypothalamus has a very critical role in regulating and maintaining the homeostasis of the body and all its cell. It controls the autonomic nervous system, endocrine system and sleep wake cycle of the body. It responds to variety of signals ranging from the emotions, body temperature, and sensations of hunger and thirst to blood pressure and stress through secretion of hormones itself or by stimulating pituitary gland or pineal gland.
