Which is a product of photosynthesis?

a)starch

b)glucose

c)water

d)carbon dioxide

Answer:-

The main product is glucose despite as the matter of fact it produces several products such as:

•Oxygen

&

•Water too.

Explanation:

The reaction of photosynthesis is given below:

6CO2 + 12H2O + (in the presence of sunlight) → C6H12O6 + 6O2 + 6H2O

Carbon dioxide + Water + Sunlight → Glucose + Oxygen + Water.

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
