<span>The most important estrogen is estradiol and the most important androgen is testosterone.</span>
Testosterone is the primary steroid male sex hormone. Its function is to control the development of male reproductive tissues, to promote secondary sexual characteristics to maintain health (the prevention of osteoporosis for example). It is synthesized from cholesterol and it achieves its effects by binding to androgen receptors on different tissues.

What term is used to describe the structure of a dna moleculrr?

notsponge [240]

A DNA molecule is made up of nucleotides.Each nucleotide is made up of a nitrogen base, a sugar molecule and a phosphate group. There are 4 nitrogen bases such as adenine and guanine known as purines, thine and cytosine are known as pyramidine. These nitrogenous base are arranged in a sequence attached to each other by hydrogen bonding into anti-parallel strands. Therefore, the structure of DNA is termed as the double helical model.

Select the five major mechanisms of antimicrobial resistance. Check All That Apply

Rudik [331]

Answer:

All the given statements are correct except b.

Antimicrobial resistance (AMR) refers to the ability of a microorganism to grow in the presence of drug or a chemical that would normally limit its growth or kill it.

It makes it difficult for the existing drugs to eliminate the infection as they become less effective against the microbe.

There are five major mechanisms by which a microbe attains resistance against antimicrobial chemical or drug:

Drug modification or inactivation: A microbial enzyme inactivates the antimicrobial agent. For example, few bacteria produce β-lactamases which provide multi-resistance against β-lactam antibiotics such as penicillin, cephalosporin etc.
Alteration or modification of target site: An altered target site prevents the antimicrobial agent from binding to its target. For example, alteration of penicillin binding protein (PBP) in Methicillin-resistant <em>Staphylococcus aureus </em>(MRSA).
Alteration of metabolic pathway: The microbe uses an alternative pathway to circumvent the blocked pathway. For example, sulfonamides-resistant bacteria started using preformed folic acid in place of para-aminobenzoic acid (PABA).
Decreased drug accumulation: Microbial efflux pumps remove the antimicrobial agent (before it could do any damage) by pumping it out of the cell.
Decrease in cell permeability: The permeability of the microbial envelope to the antimicrobial agent is decreased
