Answer:

Antimicrobial resistance occurs when microbes evolve mechanisms that protect them from the effects of antimicrobials. It's mainly caused by the overuse of antimicrobials. This leads to microbes either evolving a defense against drugs used to treat them, or certain strains of microbes that have a natural resistance to antimicrobials becoming much more prevalent than the ones that are easily defeated with medication.

The best ways to prevent antibiotic resistance are:

For every infection, it is recommended to order cultures and antibiograms before starting the therapy
Making sure that indication, dose and duration of treatment are respected according to the guidelines

Two organisms, with the genotypes FFEe and FfEE, are mated. Assuming independent assortment of the F/f and E/e genes: 1) Provide

IgorC [24]

Answer:

<h2> FFEE, FfEE, FFEe, and FfEe</h2><h2> All the progeny show same 1/4 or 25% probability.</h2>

Explanation:

Given; parents are with genotype FFFe and FfEE

F/f and E/e are showing independent assortment,

1. Genotype of all possible offspring are;

gamete from parent FFEe are; FE and Fe ,

gamete from parent FfEE are; FE and fE.

So genotype of offspring are: FFEE, FfEE, FFEe, and FfEe

2. All the progeny show same 1/4 or 25% probability.

What structure allows the hypothalamus to have direct communication with the anterior pituitary?

ANEK [815]

Hypophyseal portal system allows the hypothalamus to have direct communication with the anterior pituitary.

The hypophyseal portal system is a network of blood vessels that connects the anterior portion of the gland and hypothalamus at the base of the brain. Two capillary beds, one in the median eminence and the other in the anterior pituitary, make up the portal system. Its principal job is to swiftly transfer and exchange hormones between the anterior pituitary gland and the hypothalamic arcuate nucleus.

The cortisol, androgens, and aldosterone hormones interact with anterior pituitary gland cells via travelling through the hypophyseal portal system. Hormonal signaling through the hypophyseal portal system enables connection between these two structures.
