Please answer part a and b

1.A.this is false since M is the peak of the graph

B.this is true since oxygen is a product of photosynthesis

C.this is true since respiration still occurs and produces water but photosynthesis that consumes the water has a low intensity

D.this is false since the rate of photosynthesis is lower in I

2.A.this is false since oxygen molecules don't break down during photosynthesis

B.this is false because the temperature influences the rate of photosynthesis

C.this is true since high temperature causes damage to the cells

D.this is true because enzymes work at specific temperatures

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.

explanation:

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
