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>
The natural resource management aims at saving the natural resource for the coming generation without depriving the demand of the present generation. There must be a sufferable way to use the natural resources because unlimited use of resources will guide to some problems.
The natural resource management also seeks at using the natural resources in its pure shape and making it available to every possible place.
<h3>What are the advantages of natural resource management?</h3>
When watched for in the right way, they can help us to reduce flooding, enhance air quality and supply materials for construction. They also provide a home for some rare and stunning wildlife and iconic landscapes we can relish and which boost the economy via tourism.

yes both plant and animal cells contain an endoplasmic reticulum(ER)
Answer:
Different types of cells shapes effect the function of the cells. Muscle cells are shaped like they are because they have to perform a certain function to meet the critia of what the body is telling it what to do.
Explanation:
Skeletal muscle cells are located in a bundle of linear fibers. These are thin chains of the proteins actin and myosin that cause muscle contraction. The elongated shape of muscle cells allows contractile proteins to place themselves in an overlapping pattern that allows muscle flexion.
