Answer:
Explanation:
Sperm capacitation is the process by which the sperm becomes physiologically matured so as to facilitate the penetration and fertilization of an egg during the process of copulation. This term was coined by Conel R. Austin in 1952 through his independent studies on sperms. The recognition of this phenomena was done by in vitro fertilization experiments associated with the field of embryology and reproductive biology.
Answer:Alcoholism is a difficult disease, which includes both a psychological and physical dependence. It cannot be fixed overnight, even if a woman is pregnant. You should be a cheerleader for her and encourage her to talk to her doctor. You should also have a support system of your own, and talk on the phone with loved one when you need to, while respecting her privacy as well.
Explanation:
Answer:
Taking into account that:
The flow velocity u of a fluid is a vector field
u = u (x, t)
What gives the velocity of a Fluid Plot at position x y time t.
q = || u ||
Now if the flow is continuous as it happens in the blood vessels then:
The flow of a fluid is said to be constant if it does not move over time, that is why the variant would be 0.
Explanation:
As for the pump with narrow vessels, there the area would be less, therefore the flow also and the flow velocity as well. Adding that the friction with the walls increases as it is narrower, thus generating an increase in pressure with the flow of the liquid.
So this is where we have to put emphasis on the biophysics branch that explains the following:
The Venturi effect is explained by the Bernoulli Principle and the principle of continuity of mass. If the flow rate of a fluid is constant but the section decreases, the speed necessarily increases after crossing this section. By the theorem of conservation of mechanical energy, if the kinetic energy increases, the energy determined by the value of pressure necessarily decreases.
Indeed, according to Bernoulli's principle:
P 1 + 21 ρv 12 + ρgh 1 = P 2 + 21 ρv 22 + ρgh 2
