The big blue area is the mitochondrial matrix. This is where the citric acid cycle takes place; also known as the Krebs cycle or Tricarboxylic acid cycle. The orange, green, and red shapes are (possibly) the complexes I, III, and IV respectively. At Complex IV (red), O2 or oxygen enters and H20 or water comes out as by product. The + (plus signs) are the protons which can be depicted as H+ in some diagrams. These + / protons drive the ATP synthase (yellow) to sort of turn around like a motor; and with every turn, ADP combined with inorganic phosphate (Pi in some diagrams) comes out as ATP -- the energy currency of the cell.
Calcium channel blockers inhibit the movement of calcium ions from the interstitial fluid into cardiac and smooth muscle cells. This would cause a decrease in heart rate, stroke volume, and cardiac output. These in turn would lower blood pressure. In addition, the calcium channel blockers would also inhibit contraction of the smooth muscle in the wall of blood vessels, causing them to get wider and thus also lower blood pressure. Because both heart and smooth muscle cells are inhibited by verapamil, its effects on blood pressure are particularly potent.
Answer:
B. Peripheral nerves
Explanation:
Peripheral nerves use bundles of nerve fibers (axons) to send information around the central nervous system.
Answer:
Explanation:
In order to reach specific items of food that meet the dietary needs of the giraffe, they must reach for food up in the trees. Giraffes with longer necks are open to a wider array of food whereas the short necked giraffes are limited. The longer neck is seen to be more favorable. When a trait is more favorable, it has a higher likelihood of being passed on. The less favorable traits are eliminated or "weed" out and the taller giraffes mate with other tall giraffes, generating a greater population with this trait. Again, it is solely dependent on what is available around them and their surroundings.

The surface tension of a liquid results from an imbalance of intermolecular attractive forces, the cohesive forces between molecules.
