Heparin reacts to prevent the conversion of prothrombin to thrombin. Heparin:

Biology
1 answer:
Paha777 [63]3 years ago
7 0

Answer:

The correct option is C) Heparin has its effects reversed with the administration of protamine sulfate.

Explanation:

Heparin is an anticoagulant, that is, it works by decreasing the ability of blood to clot, helping to prevent the formation of clots as well as stopping the subsequent extension of any existing clot. Through the neutralization of thrombin, it prevents the conversion of fibrinogen to fibrin, and thus, prevents the formation of a stable clot by inhibiting the fibrin stabilizing factor.

Protamine sulfate is a heparin antagonist, forming with it inactive complexes without anticoagulant effect, that is, the protamine, in the presence of heparin, which is acidic in nature, through the formation of stable salts, cancels the anticoagulant effect of both substances, neutralizing and reversing the anticoagulant action of heparin.

Select the statements that accurately describe endocytosis. The cell membrane pinches off to form an extracellular vesicle joine
noname [10]

Answer: The cell membrane invaginates and pinches off, creating a vesicle within the cell.

Explanation:

Endocytosis is an active transport mechanism, for particules to be transported, the plasma membrane of the cell invaginates, forming a pocket around the target particle. The pocket then pinches off, resulting in the particle being contained in a newly created intracellular vesicle formed from the plasma membrane.

In what way did Shakespeare create a distinction between the educated nobility and the coarse lower classes?
stiv31 [10]
<span>This is a very simplistic question because the distinction was clearly maintained in real life and that was only carried forward into Shakespeare's plays. The most obvious difference between people of different social classes was their clothes. People were forbidden by law to dress in certain ways unless they were rich and noble enough. The costumes used in the plays showed this: the actors playing noble people wore fine clothing (the castoffs of the real nobility). 
</span><span>
</span><span>The other difference between the upper and lower class people is the way they talk. Shakespeare often puts a stately blank verse in the mouths of the upper crust and arrhythmic prose in the mouths of the common people. But not always. Even the nobility speak in prose when they are disturbed or insane, and they speak in prose all the way through Much Ado About Nothing. Prince Hal talks in prose when talking to Ned Poins. Blank verse is saved for matters of seriousness where a more poetic approach is needed. It is not, therefore, a matter of social class so much as a matter of the weightiness of what is being said (and in Shakespeare, the lower classes rarely have anything worthwhile to say).</span>
