Can someone help me thank you.

Explanation:

Because it is night time on the other side and that is due to earth rotation

The diagram shows the sun and earth, and the x is daytime because it is facing the sun this is because of the rotation of the earth. As the earth turns the sun, beams light to the earth.

for example, take a ball and torch.

put the torch on and put it on the table horizontally next to the ball turn the ball around. You can see that the light hits the ball it becomes day and the back is dark indicating night...

Hope this helps!!

d. the weight of the book

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.
