The right answr is hydrogen bonds

The hydrogen bond or hydrogen bridge is an intermolecular force involving a hydrogen atom and an electronegative atom such as oxygen, nitrogen and fluorine. The intensity of a hydrogen bond is intermediate between that of a covalent bond and that of van der Waals forces.

The helices of the DNA (both strands) are maintained by hydrogen bonds.

Answer:

brainliest plzzzzz

Explanation:

There is a proper mechanism of controlling the levels of various kinds of hormones and chemicals in our body called as positive feedback and negative feedback.

In a very simple language you can understand it as whenever there is a release of a particular hormone or chemical inside the body in very huge amount then the negative feedback of the body is activated the production of that particular hormone or chemical is stopped and vice -versa for negative feedback.

Explanation:positive feedback and negative both the feedback mechanism are achieved to maintain the proper homeostasis.

Example: release of clotting factor after blood loss is a positive feedback and a hormone is released and then suddenly there is a increase in hormone b, then the amount of hormone a will decrease this is a negative feedback.

Why do antimicrobial agents active against mycobacteria have to be administered for months or years rather than the typical 10-3
Eduardwww [97]
Antimicrobial agents active <span>against mycobacteria have to be administered for months or years rather than the typical 10-30 days prescribed to treat other infections because mycobacteria reproduce very slowly.
So, over the period of time that mycobacteria reproduce, antimicrobial agents have to be taken so as to prevent these mycrobacteria from invading the body completely. Once their reproduction is completely prevented, antimicrobial agents don't have to be administered anymore.
