Bacteriocins and defensins are types of which of the following?
leukotrienes
cytokines
inflammation-eliciting mediators
antimicrobial peptides

Antimicrobial peptides

Explanation:

Antimicrobial peptides may be defined as the important part of immune system that provide protection against the pathogens. These peptides are also known as host defense peptides.

Defensin and bacteriocins are the antimicrobial peptide. Defensin are cysteine rich protein that provide protection against bacteria, virus and cancer cells. Bacteriocin peptide is present in bacteria that inhibit the growth of the same strains of bacteria.

Thus, the correct answer is option (4).

"menstrual cycle is a complex cycle that consists of several processes. order of occurrence of steps in menstrual cycle are as follows:

1. high progesterone levels maintain the endometrium lining of the uterus.

2. endometrium lining breaks down and low levels of estrogen stimulate the pituitary to release fsh and lh.

3. fsh and lh stimulates the follicles to develop and the oocyte to produce estrogen.

4. rising estrogen levels suppress fsh production and development of other follicles.

5. a spike in lh causes follicle to rupture.

6. a breakdown of corpus luteum causes progesterone level to drop."
