Answer:
When a macromolecule contains repeated similar sub units of a particular molecule:such a repeated units are called polymers.
Therefore, polyethylene is a micromolecule of repeated subunits called ethylene formed during polymerization..Therefore, the small units joined together to form polyethylene are ethylene.These are alkene hydrocarbons,which are similar in structure with the carbon atoms linked by double bonds.When the Pi bonds of the double bonds breaks. hydrogen atoms forms free covalents bonds in all these sub units.
However, polypeptides is made of of 20 different amino acids, connected by peptides, disulfide and other bonds.Therefore the protein molecules will be different from the polyethylene and polymers. This is because each of the 20 amino acids has different R-groups, and It is this R-groups that determine the functional characteristics displayed by each amino acid sub- units.Therefore, the characteristics of a protein molecule will be determine by the type of Amino acids it contains.
Thus the beads of polyethylene will be the same, but different in proteins
Explanation:
With the overuse of chemical fertilizers, many lawns now have it to where decomposers can't live. This interferes most directly with the lawn ecosystem to recycle important nutrients. The correct answer is choice number 2.
Answer:
I believe they are called a population, tell me if I'm wrong.
Answer:
The correct answer will be option-D
Explanation:
In case the blood pressure drops in the body, the juxtaglomerular cells of the kidney start converting the prorenin into renin. This renin converts inactive angiotensin to angiotensin I which gets converted to angiotensin II by ACE enzyme.
The angiotensin II acts as vasoconstrictor narrowing the vessels and thus increasing the blood pressure. It also stimulates the secretion of aldosterone which increases the reabsorption of sodium ions and help increase the blood pressure of the blood.
Thus, option-D is the correct answer.
