It uses unicellular cells.
Answer:
4. Ribosomes are tiny glanular structures that are either floating freely in cytoplasm or are bound to endoplasmic reticulum.
5. Translation.
6. Eukaryotic ribosomes are ten times larger than prokaryotic ones.
7. Not sure about this.But they are necessary for protein synthesis as they assemble amino acids into protein chains.
8. Ribosomal RNA is part of ribosome.These complex structures catalyze the assembly of amino acids into protein chains.They also bind tRNAs and various accessory molecules necessary for proteins.
9. When a ribosome is not working,it disassembles into two smaller units.
Explanation:
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.
