3 0

Answer:D

Explanation: Because it has the least amount of density in it. All the others are heavier, meaning they will sink. Just like if you drop a rock water and a feather, the feather will float.

Density def:

Density, mass of a unit volume of a material substance. ... Density offers a convenient means of obtaining the mass of a body from its volume or vice versa; the mass is equal to the volume multiplied by the density (M = Vd), while the volume is equal to the mass divided by the density (V = M/d).

There are choices for this question namely:

a. What is your name and where do you live?
b. How much poison did you swallow?
c. How long have you been feeling this way?
<span>d. What have you recently had to eat or drink?
</span>
The correct answer is "what have you recently had to eat or drink". This will confirm the suspicion by first ruling out potential reactive foods or drinks that may have caused a similar reaction (i.e. allergic reactions). If that is ruled out, then the probing about the history of intake of poison will come next in the interview.

Answer:

ATP and NADPH are used to energy for the production of the Calvin cycle. Once their energy is released, they revert back to ADP and NADP+ and can be reused again.

Explanation:

ATP and NADPH are energy carriers that can be used to power chemical reactions. Once they have energized cellular processes, they become their 'low energy' form of ADP and NADP+. Later, they can reform ATP and NADPH to power more reactions
