Why carbon easily forms many bonds?

Biology
1 answer:
scZoUnD [109]3 years ago
8 0

The Correct Answer: C)

Because...

Each carbon is identical, they all have four valence electrons, so they can easily bond with other carbon atoms to form long chains or rings. In fact, a carbon atom can bond with another carbon atom two or three times to make double and triple covalent bonds between two carbon atoms.

<h2>Urea </h2>

Explanation:

Urea is a small nitrogenous compound which is the main end product of protein catabolism in mammals

  • Urea is a nitrogen-containing substance normally cleared from the blood by the kidney into the urine
  • It is made predominantly in the liver from ammonia and bicarbonate and is one of the main components of urine
  • The rate of synthesis varies from 300 to 600 mmol/day depending on the protein intake
  • All of this urea eventually finds its way into the urine
  • Because urea makes up a large part of the obligatory solute excretion, its osmotic pressure requires significant volumes of water to carry the urea
  • Urea passively crosses biological membranes, but its permeability is low because of its low solubility in the lipid bilayer
  • Some cells speed up this process through urea transporters, which move urea by facilitated diffusion
  • Urea is passively reabsorbed in the proximal tubule, but its route of transport is not clear
  • Urea transporters have not yet been identified for the proximal tubule

Monoclonal antibodies (mAbs) are produced by introducing an antigen to a mouse and then fusing polyclonal B cells from the mouse's spleen to myeloma cells. The resulting hybridoma cells are cultured and continue to produce antibodies to the antigen.

Explanation:

An example of a monoclonal antibody is blinatumomab (Blincyto, Amgen), used to treat certain cancer, types of acute lymphocytic leukemia.
