Answer:
B- The speed of sound will increase due to the increasing density of seawater.
Explanation:
If the temperature of seawater decreases its density increases, but only to a point
The propositions are:
a.alkylating agents
b.antimetabolites
c.topisomerase inhibitors
d.nucleoside analogs
e.<span>AZT
The right answer is A,
An alkylating agent is a compound capable of adding alkyl groups to various electronegative groups under conditions present within the cells.
Antimetabolites are an anticancer drug but act differently than the alkylating agent. (interfere with folic acid)
Topoisomerase inhibitor acts by inhibiting isomerase, used in antibiotherapy (like quinolones).
Nucleoside analogs are analogs as their name says, it does not alkylate nucleotides.
AZT (</span><span>Zidovudine) is an antiretroviral drug that inhibits reverse transcriptase.</span>
Answer:
Ecologists
Explanation
often estimate the size and density of populations using quadrats and the mark-recapture method. A population can also be described in terms of the distribution, or dispersion, of the individuals that make it up. Individuals may be distributed in a uniform, random, or clumped pattern.
