The answer is pyruvate. In the absence of oxygen in
anaerobic respiration, the pyruvate is converted to lactic acid in animals and
ethanol in plants. However, in the presence of oxygen, the pyruvate enters the Krebs
cycle after being converted to Acetyl CoA. Pyruvate is an intermediate product
of glycolysis.
Answer:
By exercising, it increases blood flow towards the muscles and digestive tract. This can help move food through the stomach, or digestive tract.
If you wanted to increase the rate of photosynthesis in a plant, you would develop a plant with many, broad leaves. This helps to get more sunlight. The correct answer is C, many, broad leaves.
The bare soil surface type affects the amount of runoff because it has
no other stopping mechanism that prevents runoff to happen. Just like in the
use of pesticide, it is
harmful to human agriculture because it contains an antifreezing chemical
(present in transportation vehicles). When the chemical seeps into the soil, it
will create a runoff and can seep into the groundwater causing pollution.

A
Explanation:
Photosynthesis produces carbon dioxide (chemical gas) which is used in cellular respiration to make oxygen. That oxygen is then used in photosynthesis to make more carbon dioxide and so on.
