Mitral valve prolapse causes blood to leak back into the __________ when the ventricles contract.

1 answer:

I think the correct answer would be the left atrium. Mitral valve stenosis is the narrowing of the mitral valve in the heart. This valve does not properly open which blocks the flow of blood into the left atrium. Hope this answers the question.

Leya [2.2K]

Answer:

rapid movement of solid particles mixed with water: mudflow
slow movement of solid particles down a slope: creep
rapid movement of solid particles down a slope: landslide
rapid movement of solid particles mixed with water: earthflow

Explanation:

An earthflow is intermediate to mudflow and creep. It is the type of mass wasting that involves movement of solid particles saturated with water, not necessarily mixed with large quantities of it.

What happens to the gravitational force between two objects if they move CLOSER?

mr Goodwill [35]

$\qquad\qquad\huge\underline{{\sf Answer}}$

As we know ~

Gravitational Force acting on two objects can be easily represented by formula :

$\qquad \sf \dashrightarrow \:F = \dfrac{Gm_1m_2}{r²}$

so, from above we get :

$\qquad \sf \dashrightarrow \:F \propto \dfrac{1}{r²}$

We can conclude from derived information that, Gravitational force is inversely proportional to the distance between the objects. so if the objects move closer to each other. value of r decreases. hence we can say that Gravitational force increases.

Therefore, the correct choice is A. It increases

Certain exposures to radiation can cause cancer. What is the main difference between the use of radiation treatments to treat ca

jonny [76]

the radiations that are used to treat cancers are of the gamma type. primarily emitted from cobalt-60 (a radioactive isotope). and it is more controlled than other radiation exposures. i.e. solar radiation which is not controlled.

hope that this helps.
