1 answer:

4 0

<span>The specific heat of the metal is 0.5 cal/ (0C.g). This means the energy needed is 0.5 cal to raise the heat of 1 gram of metal by 1 degree C. Therefore, the energy needed to raise 100 g of the metal by 20 degrees C is:
0.5 * 20 * 100 = 1000 cal.

Answer:

C. CALVIN CYCLE(LIGHT INDEPENDENT REACTIONS OF PHOTOSYNTHESIS.

Explanation:

Photosynthesis is the process whereby green plants manufacture their food (organic matters in form of glucose) from carbon IV oxide and water molecules in the presence of sunlight.

The glucose formed undergoes two purposes; provision of energy and in the fixing of carbon.

This process involved two steps : The light dependent process and the light independent (Calvin cycle).

The light dependent reaction takes place in the thylakoid membrane and requires supply of light energy.

ATP and NADPH are formed, water molecules are also formed.

The light independent reaction occurs in the stoma and does not require light energy. The process used the ATP and NADPH formed from the light dependent reaction to fix carbon and produce three carbon sugars.

So the Calvin cycle light independent reaction is involved in the fixing of carbon molecules into organic molecules in the absence of sunlight and the ATP and NADPH formed from the light dependent process of photosynthesis.

The right answer is: Leptin .

Leptin is a hormone closely linked to the regulation of energy consumption and expenditure: appetite, metabolism, and hunger.

A hormone is a protein with a messenger function. This means that once released into the bloodstream, she goes to another part of the body to transmit a message to specific receptors.

Leptin is manufactured in white adipocytes (adipose tissue) where triglycerides (fats) are stored and acts on the hypothalamus.
