Answer: b) virus
explanation: viruses depend on the host cells that they infect to reproduce or “replicate”. though they can survive outside of a host, they cannot reproduce without a host.
The hydrologic cycle is a continuous cycle where water evaporates and travels into the air and becomes part of a cloud and falls down as precipitation and then evaporates again. Then the cycle repeats in a never ending cycle.
First one is a
the
second one is b
The second reaction with the volume of 5L will occur faster as compared to the first reaction of volume 10L.
Volume is inversely proportional to the rate of reaction.
As volume increases rate of reaction decreases and as volume decreases rate of reaction increases.
Let's consider a reaction A → B.
r is rate of reaction and K is rate constant, A is the concentration of reaction.
r = k(A)
r is directly proportional to the A.
But the concentration of A is in Moles/liters (i.e. moles per unit volume)
r is inversely proportional to the volume of vessel or chamber.
Hence as volume increases rate of reaction decreases.

C. It show how many moles are used of each substance.
