Answer the following question given this paragraph: An alkaline battery is a variation on the zinc-carbon dry cell. The alkaline battery has no carbon rod and uses a paste of zinc metal and potassium hydroxide instead of a solid metal anode. The cathode half-reaction is the same, but the anode half-reaction is different. Q: Deficiency of what is symptomized by nausea, fatigue and dizziness, and can be triggered by excessive sweating? Choices: - impurities - salts - calories - electrolytes A:
electrolytes
Q: Answer the following question given this paragraph: Osmosis is the special case of the diffusion of water. It's an important means of transport in cells because the fluid inside and outside cells is mostly water. Water can pass through the cell membrane by simple diffusion, but it can happen more quickly with the help of channel proteins. Water moves in or out of a cell by osmosis until its concentration is the same on both sides of the cell membrane. Q: What is the diffusion of water known as? Choices: - evaporation - electrolysis - hemostasis - osmosis A:
A: osmosis

Answer the following question given this paragraph: Regulation of Blood Glucose Levels by Insulin and Glucagon Glucose is required for cellular respiration and is the preferred fuel for all body cells. The body derives glucose from the breakdown of the carbohydrate-containing foods and drinks we consume. Glucose not immediately taken up by cells for fuel can be stored by the liver and muscles as glycogen, or converted to triglycerides and stored in the adipose tissue. Hormones regulate both the storage and the utilization of glucose as required. Receptors located in the pancreas sense blood glucose levels, and subsequently the pancreatic cells secrete glucagon or insulin to maintain normal levels. Q: What does the body derive from the breakdown of the carbohydrate-containing foods and drinks we consume? Choices: - insulin - lipids - amino acids - glucose A:
**Answer**
glucose
