noname [10]3 years ago
4 0

Answer:

The correct answer will be option-A

Explanation:

Colchicine is the drug that prevents the assembly of the mitotic spindles which halts or stops the cell cycle.

The colchicine acts by inhibiting the microtubule polymerization thus mitotic spindles which takes place after the condensation of the chromosomes during prophase and pre-metaphase.

This acts as checkpoint which can halt the cell cycle at the phase of chromosome condensation.

Thus, option-A is the correct answer.

a diver with a mass of 60 Kg is standing on the top of a 10 meter high platform. what is the mechanical energy
inna [77]

Answer:

M.E = 5880 J

Explanation:

Given data:

Mass = 60 Kg

Height = 10 m

Mechanical energy = ?

Solution:

Formula:

M.E = K.F + P.E

K.E = 1/2 × mv²

P.E = mgh

Diver is not moving so K.E will be zero.

M.E = mgh

M.E = 60 kg × 9.8 m/s² ×  10 m

M.E = 5880 J  ( j= kg m²/s²)

<h3>What is Cardiology?</h3>
  • Cardiology is a field of medicine that deals with problems with the heart and cardiovascular system.
  • The term "cardiology" comes from the Ancient Greek words "kardi" (heart) and "-logia" (study).
  • Heart failure, valvular heart disease, congenital heart defects, coronary artery disease, and electrophysiology are all covered in the field's spectrum of medical diagnosis and treatment.
  • Cardiologists are among the professionals in internal medicine who work in this area.
  • Pediatricians that specialize in cardiology are known as pediatric cardiologists.
<h3>Why does cardiac happen?</h3>
  • Nearly all heart conditions that are known to exist can result in cardiac arrest.
  • The electrical system of a damaged heart malfunctions most frequently during cardiac arrests.
  • An aberrant heart rhythm like ventricular tachycardia or ventricular fibrillation is brought on by this defect.

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.
