A brown bird was crossed with a white one and all of the offspring were tan. Complete a Punnett Square analysis for this pair to
Alex73 [517]

Answer:

here.

Explanation:

The genes coding for colour show codominance. Both the brown and white pigment are equally expressed in the phenotype to give the tan colour.

Considering that the allele for brown pigment is CB and that for white pigment is CW, the genotype for the brown bird is CB CB and that for the white bird is CW CW.

Crossing CB CB × CW CW,

100% CB CW - tan-coloured birds

Which of the following host defenses is considered the most effective in combating S. aureus infection?
LiRa [457]

Phagocytic response is considered the most effective host defenses in combating S. aureus infection.

<h3>What is phagocytic response?</h3>

Phagocytosis is a type of cell response that plays a key role in the course of an immune response as well as in the remodeling of tissues and the healing of wounds. Professional phagocytes are specialized cells that can carry out this task quite effectively.

<h3>What is S. aureus infection?</h3>

It has long been known that S. aureus is one of the most significant germs that harm humans. It is the main contributor to skin and soft tissue infections such cellulitis, furuncles, and abscesses (boils). Boils are the most typical staph infection form. This is a pus-filled pocket that forms in an oil gland or hair follicle. Typically, the skin around the infected area turns red and swells. To treat staph infections, doctors frequently administer cefazolin, nafcillin, oxacillin, vancomycin, daptomycin, and linezolid. Vancomycin may be necessary for staph infections that are severe. This is due to the fact that a large number of staph bacterium strains have developed resistance to other common antibiotics.

Thus from above conclusion we can say that phagocytic response is considered the most effective host defenses in combating S. aureus infection.

Which hormone released by the highlighted structure inhibits the secretion of fsh only inhibin?
qwelly [4]

Inhibin hormone released by the highlighted structure inhibits the secretion of FSH only.

<h3>What is inhibin hormone?</h3>
  • A protein called inhibin is secreted by the granulosa cells in women and the Sertoli cells in men.
  • It decreases the amount of LH-releasing hormone in the hypothalamus and prevents the pituitary gland from producing and releasing follicle-stimulating hormone.
  • Inhibin is a factor in the feedback control of FSH secretion in both males and females going through puberty.
  • Follistatin suppresses FSH-subunit expression like inhibin, whereas activin enhances it, which in turn influences FSH production and secretion.
  • Inhibin A is secreted by the corpora lutea and dominant ovarian follicles in women, which helps to explain why levels are so high during the late follicular and luteal stages.
  • During the late luteal and early follicular phases of the menstrual cycle, inhibin B is reciprocally raised.
