Answer 1

Explanation:

1) (A) Right Atrium

The blood entering the right side of your heart is low in oxygen. This is because oxygen is removed from your blood as it circulates through your body's organs and tissues.

2) (B) Humidity

The process by which the ‘green plants’ prepare its own food with help of water, carbon dioxide and sunlight it is called as photosynthesis. The plant releases ‘glucose and oxygen’ as the end product of the photosynthesis process.

The three factors which has vital as well as determining role in case of photosynthesis are:

Light

Carbon dioxide

Temperature

Humidity doesn’t have any role in photosynthesis and thus it doesn’t affects the rate of ‘photosynthesis processes’.  

Answer 2

Answer:

1.Right ventricle

Explanation:

As the lower chambers contract, blood is pumped to the lungs from the right ventricle and to the body from the left ventricle: Blood carries oxygen. The right side of the heart pumps oxygen-poor blood from the body to the lungs, where it receives oxygen.

2.Although the light dependent reactions of photosynthesis are not affected by changes in temperature, the light independent reactions of photosynthesis are dependent on temperature. They are reactions catalysed by enzymes. As the enzymes approach their optimum temperatures the overall rate increases.
