Answer:
The majority of granitic magmas are formed by melting near the base of the continents. The magmas slowly rise through the crust like great balloons. They solidify near the surface to form gigantic bodies of igneous rock called plutons, which are exposed later when uplift and erosion remove the overlying rock.
Explanation:
The answer is Forests and Oceans. Both of them occupy most of Earth's surface, Reflects the least amount of sun, and absorbs a lot of the sun's energy due to photosynthesis and photosynthetic organisms.
OPTIONS:
a) Blood delivers calcium and phosphate ions that are needed for building bone extracellular matrix.
b) Blood carries carbon dioxide to body tissues and removes oxygen for use by other organs.
c) Blood carries newly absorbed nutrients and water to the liver.
d) Blood circulates cells and chemicals that carry out immune functions.
e) Blood delivers clotting factors and WBCs that aid in hemostasis when skin is damaged
Answer:
b) Blood carries carbon dioxide to body tissues and removes oxygen for use by other organs.
Explanation:
Options a, c, d, e are all true statements about the contributions of the cardiovascular system to other body systems except option b which states that “Blood carries carbon dioxide to body tissues and removes oxygen for use by other organs”.
Actually, the cardiovascular system works together with the respiratory system to supply oxygen to body tissues as blood is circulated in the body, while carbon dioxide is removed from the body at the lungs. <em>In order words, carbon dioxide is removed, while oxygen is picked up as blood is transported through the capillaries of the lungs.

Answer:</h2>
Glucokinase or Hexokinase is a enzyme used at the first step of glycolysis.
<h2>
Explanation:</h2>
- Glucokinase is a Isoenzyme(enzymes which differs in the sequence of amino acids but catalyses the same reaction) of Hexokinase .
- Glucokinase (hexokinase D) is present only in liver and pancreas whereas hexokinase is present in all cells.
- In first step of glycolysis i.e formation of glucose-6-phosphate from glucose is completed with the help of hexokinase. In this step a ATP molecule is consumed i.e ATP is converted to ADP
Result: Glucokinase and hexokinase are used in the first step of glycolysis.
The statement is true. Atelectasis is the collapse or closure of a lung resulting in reduced or absent gas exchange. It may effect part or all of a lung. An airway blockage also can cause Atelectasis. A blockage may be due to a foreign object, a mucus plug, lung cancer, or a poorly placed breathing tube from a ventilator. When a blockage occurs, the air that's already in the air sacs is absorbed into the bloodstream.
