How do female reproductive hormones work to ensure survival of a zygote in the luteal stage of the menstrual cycle

The two main gonadotrophins in females are FSH (follcile stimulating hormone) and LH (luteinising hormone). FSH is primarily responsible for the recruitment and growth of follicles in the ovary during the fo...

Differentiate: sin(x) + 2x^2

To tackle this problem, we will spilt the two terms given. Firsly, we'll take the sin(x) by itself: d/dx (sinx) = cos(x) - where d/dx means the differential of what is inside the bracket. This is a key diffe...

Explain how and why the diffraction pattern of electrons passing through a slit depends on their momentum.

To understand this question, we have to consider the wave-particle duality of electrons. When passing through a slit, electrons exhibit a wavelike property- they diffract or spread out like a wave passing th...

The curve C has equation 2x^2y+2x+4y-cos(pi*y)=17 A) Use implict differenciation to find dy/dx B) point P(3,0.5) lies on C, find the x coodinate of the point A at which the normal to C at P meets the x axis.

A) dy/dx = (-4xy-2) / (2x 2 +4+pi sin(pi y) B) (62+3*pi) / (22+pi)

Explain the change of quark character associated with the beta-plus decay and deduce the equation.

First, we can deduce the equation for beta-plus decay in terms of the nucleons. We know a positron, ß + (antilepton), is produced, so to conserve lepton number an electron neutrino, v e (lepton), must also b...
