11. The blood electrolytes—sodium, potassium, chloride, and bicarbonate—help regulate nerve and muscle function and maintain acid-base balance and water balance. ... Thus, having electrolytes in the right concentrations (called electrolyte balance) is important in maintaining fluid balance among the compartments./12. Your adrenal glands are responsible for producing hormones that are vital to your survival. Addison's disease is a rare disease that can decrease the amount of hormones produced by your adrenal glands. People with this disease experience salt cravings, in addition to other symptoms: severe fatigue or lack of energy./13. Acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (H+) ions while bases produce hydroxide (OH-) ions in solution./14. The pH scale measures how acidic or basic a substance is. The pH scale ranges from 0 to 14.0-6 acid, 7 neutral, 8-14 basic/15. Acidosis refers to an excess of acid in the blood that causes the pH to fall below 7.35, and Alkalosis refers to an excess of base in the blood that causes the pH to rise above 7.45./16. Sperm= semen: the male reproductive fluid, containing spermatozoa in suspension. Oocyte: a cell in an ovary that may undergo meiotic division to form an ovum./17. Before entering meiosis I, a cell must first go through interphase. As in mitosis, the cell grows during G1, copies all of its chromosomes during S phase, and prepares for division during G2./Meiosis I/Prophase I; differences from mitosis begin to appear. As in mitosis, the chromosomes begin to condense, but in meiosis I, they also pair up. Each chromosome carefully aligns with its homologue partner so that the two match up at corresponding positions along their full length.
