Answer:
Because they are yet to perform photosynthesis, which requires sunlight
Explanation:
The leaves of plants are the site of a unique process called PHOTOSYNTHESIS. Photosynthesis is the process by which plants synthesize their food in form of glucose in the presence of sunlight. The glucose they synthesize is however, stored as STARCH (a carbohydrate polymer) in the leaves. This is why the leaves of a plant will naturally test positive for starch at certain times.
However, the leaves of plants will not test positive for starch early in the morning but do so at the end of the day because the leaves of that particular plant is YET to undergo photosynthesis due to lack of light from sun. However, at the end of the day, it would have performed photosynthesis and synthesize sugar and hence, test positive.
Answer:
When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP). Likewise, energy is also released when a phosphate is removed from ADP to form adenosine monophosphate (AMP).
A species is a group of organisms capable of mating and producing offspring. This is another way of saying that a species is reproductively isolated.
Answer:
Explanation:
It removes H2O from the atmosphere during acetyl CoA formation. It releases H2O to the atmosphere during the citric acid cycle.
