Answer:
45 moles
Explanation:
From glycolysis, 1 mole of glucose gives 2 moles of pyruvate which undergoes citric acid cycle.
1 mole of pyruvate undergoes citric acid cycle (After conversion to acetyl-CoA) gives 3 moles of NADH.
Also,
2 moles of pyruvate undergoes citric acid cycle (After conversion to acetyl-CoA) gives 6 moles of NADH.
Thus,
6 moles of NADH are produced from 2 moles of pyruvate or 1 mole of glucose.
1 mole of NADH is produced from 1/6 mole of glucose
267 moles of NADH are produced from 
moles of glucose.
<u>Thus, moles of glucose needed to be broken ≅ 45 moles</u>
Plants maintain water balance by opening and by closing stomata.
Explanation:
When plants are not getting enough water the tips as well as the edges of the leaves start drying and ultimately it turns brown in color. And when all the leaves turn brown the plant ultimately dies.
When light is travelling from the air to the water , the movement slows down and thus there is a little change in the direction. Thus we can say a light bend occurs when the light moves towards denser medium.
There is a thing called gravity. Gravity in the earth causes anything to stay down. There was an experiment a person held a plastic box with bricks on earth. It was really hard to pick it up. Then in the ISS (International Space Station) the same person help and it was so much easier no hardship at all, even a baby can do it!!

Mixture is a material made up of two or more different substances which are mixed. A mixture refers to the physical combination of two or more substances in which the identities are retained and are mixed in the form of solutions, suspensionsand colloids.[1][2]
Mixtures are one product of mechanically blending or mixing chemical substances such as elements and compounds, without chemical bonding or other chemical change, so that each ingredient substance retains its own chemical properties and makeup.[3]Despite that there are no chemical changes to its constituents, the physical properties of a mixture, such as its melting point, may differ from those of the components. Some mixtures can be separated into their components by using physical (mechanical or thermal) means. Azeotropes are one kind of mixture that usually pose considerable difficulties regarding the separation processes required to obtain their constituents (physical or chemical processes
