Please help!!! <br><br> What common items are PCR and restriction enzymes similar to?
IceJOKER [234]
Restriction enzymes can also be used to generate compatible ends on PCR products. In all cases, one or more restriction enzymes are used to digest the DNA resulting in either non-directional or directional insertion into the compatible plasmid. The most common Type II enzymes are those like HhaI (NEB #R0139), HindIII (NEB #R0104), and NotI (NEB #R0189)

WILL GIVE BRAINLIEST
Len [333]
<span>The trick here is to understand the definition of each of the cellular transport or function mechanisms listed. These are some interesting (and strange) analogies!

Facilitated Diffusion
This is when a mechanism assists in diffusing (spreading) some material into an environment. The dog on the wagon going through a spring loaded door would shoot it out into the environment. This is an odd analogy but Point 3 would be the one.

Active Transport 
Is when energy is expended to transport molecules somewhere against a concentration gradient or some other barrier. Examples include transporting molecules across a cell wall. The best analogy is the dog being dragged into a bathtub (Point 1).

Phagocytosis 
This is when a larger cell consumes a molecule often like eating. This matches to point 2 - the child eating the doughnut.

Passive Diffusion
Is when a concentration of molecules naturally diffuse into an environment. This suits point 5 - the crowded room full of people.

Pinocytosis
Is the budding of cell membranes to consume liquid in the surrounding environment. I guess a woman drinking tea is the closest analogy listed (Point 4).</span>

A 66-year-old patient's echocardiogram reveals a hypertrophied left ventricle, normal chamber volume, and a normal ejection frac
zheka24 [161]
This is a case of a hypertrophic cardiomyopathy with preserved ejection fraction. A hypertrophied left ventricle is a echocardiographic sign that there is chronic stress put in the left ventricle, most commonly in overcoming high aortic pressures in patients with systemic hypertension. In this case, there is normal chamber volume and normal ejection fraction therefore the heart is functionally normal and ejection fraction is preserved.
