Heart murmurs caused by a stenotic mitral valve

choose the correct

a) are heard as a high pitched click when the valve should be—but is not—wide open during systole.

b) are detected due to the turbulent blood flow that occurs as blood backflows into the left atrium

c) are detected if the valve's cusps are thin and flexible

d) all of the listed responses are true.

B) are detected due to the turbulent blood flow that occurs as blood backflows into the left atrium

Explanation:

This is caused due to narrowing of the hearts mitral valve.

It is a valvular heart disease condition

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure

[ answer ]

foliated

[ explanation ]

foliation forms in a rock when pressure squeezes the rock together. the rock then has a design of many different color little lines. there are three types of foliated rock. the types are slate, schist, and gneiss. each type of foliated rock is different based on grain size and foliation characteristics. the lines appear when the rock has been under pressure.
