Answer:
To move substances against a concentration or electrochemical gradient, a cell must use energy. Active transport mechanisms do just this, expending energy (often in the form of ATP) to maintain the right concentrations of ions and molecules in living cells.
Explanation:
Answer:
B) Nucleotide
Explanation:
This is because Nucleotides are made up of three things: Phosphate, Sugar, and a Base. Nucleotides are what make up DNA and RNA, and are considered the basic building blocks of DNA and RNA. To get a little off topic, the 4 bases types of bases are adenine, thymine, cytosine, and guanine.
I hope this helps!

When the terminal (third) phosphate is cut loose, ATP becomes ADP (Adenosine diphosphate; di= two), and the stored energy is released for some biological process to utilize.
Below are the questions:
A) A hovering mosquito is hit by a raindrop that is 45 times as massive and falling at 8.9m/s , a typical raindrop speed. How fast is the raindrop, with the attached mosquito, falling immediately afterward if the collision is perfectly inelastic?
<span>B) Because a raindrop is "soft" and deformable, the collision duration is a relatively long 8.0 ms. What is the mosquito's average acceleration, in g's, during the collision? The peak acceleration is roughly twice the value you found, but the mosquito's rigid exoskeleton allows it to survive accelerations of this magnitude. In contrast, humans cannot survive an acceleration of more than about 10 g.

Below are the answers:
a. <span>MU = (M + m)V; where M = 45 m, U = 8.9 m/s, find V = ?. V = (45/46)*8.9 = 8.7 m/s
</span>
b. <span>F = m dV/dT = m 8.7/8E-3 = m 1.0875E+03; so G = 1.0875E+03/9.8 = 111 G's.</span>
