<span>Both protexts the organisms' organelles which are inside the cell.
Animal Cell: Cell Membrane
Plant Cell: Cell Wall
Cell
wall is present only in plants, it is not found in all organisms.
Compared to the cell membrane, a cell wall is thick and has a rigid
structure. You can see it in a light microscope, because it is visible.
It serves as the protective cover that surrounds the plasma membrane in a
plant cell. Cell membrane is composed of lipids. Cell walls can be made
up of cellulose or peptidoglycan or chitin.<span> </span></span>
Answer:
c. Increased reabsorption of phosphate in the kidneys
d. Increased deposition of calcium into the bones.
Explanation:
Hyperphosphatemia is a condition that is expressed particularly in people with a kidney dysfunction. It comprises the kidneys, which do not excrete enough phosphate from the body as they reabsorbe it and thus leading to increased phosphate levels.
Also, phosphate binds calcium with high affinity, provoking acute hypocalcemia (decreased levels of calcium). In Hyperphosphatemia, calcium is being deposited mostly in the bone but also in the extraskeletal tissue.

Answer: DNA has three components a phosphate group, a sugar deoxyribose and 4 nitogenous bases.
DNA has two important bonds that make up the DNA which are phosphodiester bond and hydrogen bonds.
Explanation:
The phosphate of the one nucleotide in DNA bonds with the 5 sugar (5' carbon) of the next nucleotide forming the PHOSPHODIESTER BOND which is a strong covalent bond.
The other bond in DNA is the hydrogen bonds which are among the nitrogenous bases.
There are four bases adenine,guanine,cytosine,thyamine
These bases are held together by strong hydrogen bonds.
Adenine and thyamine have two hydrogen bonds between them and cytosine and guanine have three hydrogen bonds between them.
These hydrogen bonds keeps the DNA helix in place.
