Answer:
Cellular differentiation is the process by which a less specialized cell matures into a more specialized cell. It is a part of developmental biology.
Answer:
Lungs supply oxygen carried by blood to cells of the body. The cells which are responsible for the transportation of oxygen is hemoglobin. When oxygen rich hemoglobin reaches a cell so the oxygen is unloaded and carbondioxide which is produced as a waste product is loaded in hemoglobin. Again this hemoglobin goes to the lungs and dispose carbondioxide there and repeat the process again.
It would die after harmful substances entered the cell. This would happen because it would burst due to over-bulging.
Answer:
C. They contain sugars, phosphate, and nitrogenous bases
Explanation:
A. is wrong because only RNA is made up of single strands of nucleotides, while DNA is a double-stranded helix.
B. is wrong because DNA and RNA are examples of nucleic acids, not carbohydrates
D. is wrong because only RNA contains uracil, while DNA has thymine instead of uracil.
C. is correct because both DNA and RNA have sugar-phosphate backbones and nitrogenous bases. The difference between RNA and DNA is seen in their names--deoxyribo nucleic acid (DNA) vs. ribo nucleic acid (RNA). Ribose is a type of sugar, the same as found in RNA, while deoxyribose (in DNA) is the same except for not having an oxygen atom on the 2' Carbon (de-oxy = without oxygen).
