Answer:
The correct answer will be options-A and D.
Explanation:
Photosynthesis is a complex process which forms the glucose, the energy molecule of the plant. Photosynthesis takes place in the two phases: light-dependent reaction and light-independent reactions.
The light-dependent reaction leads to the breakdown of the water molecule which produces oxygen whereas in light-independent reaction, the carbon dioxide gets fixed during the carboxylation step of cycle utilizing the carbon dioxide.
Therefore, if photosynthesis takes place then it will lead to a rise in the level of oxygen and reduction in the amount of carbon dioxide. Thus, options-A and D are the correct answer.
Well if the small intestine needs to absorb the nutrients, then the nutrients kind of have to go somewhere right?
also, there is a transfer from high to low
inside the small intestine there are lots of nutrients that need to be absorbed to be made into energy
the cells would only have to take in more nutrients if it has run out, aka it's low on nutrients
thus the high concentration outside the cell and the low concentration inside leads to the active transport through the cell membrane
It would be the muscles because their contracting and forcing the blood back to the heart
Valence is the number of electrons an atom must gain or lose in order to consummate its outer energy level or have a stable octet in its outer shell
