2. How does the increase in the level of testosterone affect the production of GnRH, FSH and LH?

maria [59]

Answer:

The correct answer is - option B. The increase in testosterone prevents further production of GnRH, FSH, and LH

Explanation:

The high level of testosterone hormone produced by the testes shows a negative feedback system in males as an increase in this hormone leads to the inhibition of the GnRH from the hypothalamus and which in turn inhibits the production of the fH and FSH from the pituiyary gland.

This process in a negative feedback system which prevents the production of hormone by released by the same hormone. It leads to slow spermatogenesis

How far away can a proton and an electron be from each other, such that they still exert an electric force on each other of magn

pogonyaev

Answer:

$\sqrt{ \frac{2.3 *10^{-28} }{F} }$

Explanation:

Total force = Force due to gravity + Force due to charges

Total force = $\frac{GMm}{r^{2} } + \frac{kQq}{r^{2} }$

r is the separation between particles.

Charge of a proton(Q) = - (charge of an electron(q) ) = 1.6 * 10^-19 coulombs

Mass of a proton (M)= 1.67×10^-27 kilograms

Mass of an electron (m) =9.11 × 10^-31 kilograms

G=6.67 ×10^−11 N⋅m^2/kg^2

k=8.99 * 10 ^9 N.m^2 / C^2

Plugging in values:

Force due to gravity= (6.67 *10^−11)(1.67 * 10^-27)*(9.11 * 10^-31) /r^2 =1.01 * 10^-67 / r^2

Force due to charges : (8.99 * 10 ^9)*(1.6 * 10^-19)*(1.6 * 10^-19) / r^2 = 2.3 *10^-28 / r^2

We can observe that force due to charges is too large as compared with force due to charge. The ratio of Fc to Fm is 2.3* 10^39. It means that we can ignore force due to gravity.

Total force = Force due to charges.

F = 2.3 *10^-28 / r^2

r = $\sqrt{ \frac{2.3 *10^{-28} }{F} }$
