<span>Compare: both RNA and DNA have 3 nitrogenous bases: Adenine Cytosine and Guanine. Also b</span>oth have a phosphate groups in their nucleotides<span>
Contrast: </span>RNA is a polymer with a ribose AND a phosphate backbone. It has four different nitrogenous bases: adenine, guanine, cytosine, and uracil.
DNA<span> is a long polymer with deoxyriboses AND phosphate backbone. It also has four </span>different<span> nitrogenous bases: adenine, guanine, cytosine and thymine.

Answer:
Carbon dioxide, which is naturally in the atmosphere, dissolves into seawater. Water and carbon dioxide combine to form carbonic acid (H2CO3), a weak acid that breaks (or “dissociates”) into hydrogen ions (H+) and bicarbonate ions (HCO3-).

Answer:
The correct answer will be-False
Explanation:
Calcitonin is a hormone produced by the parafollicular cells present in the thyroid gland.
The Calcitonin plays an important role in the human body as they reduce the level of phosphate and calcium in the blood.
The calcitonin is produced by the C-cells in response to the amount of the calcium levels in the blood as a high concentration of calcium cause release of calcitonin.
Since the calcitonin is involved in the regulation of calcium of blood and not bones therefore, false is the correct answer.
I think its D but I'm not sure
Because of the Earth's revolution, a solar day is slightly longer than a sidereal day. In every day life, we use solar time. The Earth must rotate an extra 0.986 degrees between solar crossings of the meridian. Therefore in 24 hours of solar time, the Earth rotates 360.986 degrees.
