Astudent drew the following model.
carbon dioxide + > sugar + oxygen
what does the model represent?

a. how plants transform light into stored chemical energy
b. how energy is released from sugar molecules
c. how the sun delivers thermal energy to earth
d. how bacteria transform nitrogen into a usable from

The correct answer is-

A. How plants transform light into stored chemical energy.

The given equation in the model of the represents word equation for photosynthesis.

Photosynthesis is a process of formation of food ( that is a carboydrate)  in green plants and algae using CO2 (carbon dioxide) and H2O (water) in the presence of sunlight.

During this process, a green pigment in the chloroplast called chlorophyll, absorbs solar energy and converts it into chemical energy in the form of ATP and NADPH.

In the next phase, which is a light independent phase ,the chemical energy is utilized in the formation of glucose, which is a food molecule for green plants and algae.

Thus, option A) is the right answer.

answer; a muscle cell, another neuron and a of the above

the level of progesterone is low at the pre-ovulatory phase of the cycle but it gradually increases and the levels are high at the luteal phase. if pregnancy occurs, the level of progesterone will be high throughout the pregnancy.

if egg is fertilized and the mother gets pregnant, progesterone starts preparing the uterus for the implantation. it starts building up the lining of uterus and make it hostile of the period of pregnancy.
