Answer:

The answer is "Photosynthesis creates glucose (sugar) which is used in cellular respiration."

Explanation:

Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water. While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration. We breathe in that oxygen, which is carried through our blood to all our cells. In our cells, oxygen allows cellular respiration to proceed. Cellular respiration works best in the presence of oxygen. Without oxygen, much less ATP would be produced.

When a pregnant woman ingests substances, the interaction of one substance with another often ______ the effects of one or both?
Anestetic [448]
Increases

In women that are pregnant, the effects of substances are far more adverse than they would be in a normal person, especially if the woman is taking more than one. For this reason, it is important for pregnant women to take as much care as possible of their bodies and refrain completely from smoking and drinking alcohol, as both of these activities are detrimental towards the fetus's health. Pregnant women should even avoid second hand smoke from cigarettes.
