Answer the following question given this paragraph: Fertilization The fusion of a sperm and an egg is a process called fertilization. This can occur either inside ( internal fertilization) or outside ( external fertilization) the body of the female. Humans provide an example of the former, whereas frog reproduction is an example of the latter. Q: What is the process of the fusion of a sperm and an egg called? Choices: - Sperm - embryo - stimulation - fertilization A:
fertilization

A crystal of sodium chloride, shown here, is a collection of alternating sodium and chlorine ions. Q: What does the precise pattern of a crystal depend on? Choices: - chance - mass - age - compound A:
compound
Q: Answer the following question given this paragraph: 39.4 Transport of Gases in Human Bodily Fluids Hemoglobin is a protein found in red blood cells that is comprised of two alpha and two beta subunits that surround an iron-containing heme group. Oxygen readily binds this heme group. The ability of oxygen to bind increases as more oxygen molecules are bound to heme. Disease states and altered conditions in the body can affect the binding ability of oxygen, and increase or decrease its ability to dissociate from hemoglobin. Carbon dioxide can be transported through the blood via three methods. It is dissolved directly in the blood, bound to plasma proteins or hemoglobin, or converted into bicarbonate. The majority of carbon dioxide is transported as part of the bicarbonate system. Carbon dioxide diffuses into red blood cells. Inside, carbonic anhydrase converts carbon dioxide into + + carbonic acid (H2CO3), which is subsequently hydrolyzed into bicarbonate (HCO 3 ) and H . The H ion binds to hemoglobin in red blood cells, and bicarbonate is transported out of the red blood cells in exchange for a chloride ion. This is called the chloride shift. Bicarbonate leaves the red blood cells and enters the blood plasma. In the lungs, bicarbonate is transported back into the red blood cells in exchange for chloride. The H+ dissociates from hemoglobin and combines with bicarbonate to form carbonic acid with the help of carbonic anhydrase, which further catalyzes the reaction to convert carbonic acid back into carbon dioxide and water. The carbon dioxide is then expelled from the lungs. Q: In the lungs, bicarbonate is transported back into the red blood cells in exchange for what? Choices: - phosphate - glucose - oxygen - chloride A:
A: chloride

Answer the following question given this paragraph: When we consider a chemical reaction, we need to take into account both the system and the surroundings. The system includes the components involved in the chemical reaction itself. These will often take place in a flask, a beaker, a test tube, or some other container. The surroundings include everything that is not part of the system. When potassium reacts with water, part of the heat energy generated in the reaction is released into the surroundings. The boundary between system and surroundings is arbitrary, and it is generally chosen in a way that makes observations and calculations easier. Q: When we consider a chemical reaction, we need to take into account both the system and what? Choices: - date - fluctuations - time - sorroundings A:
(Answer)
sorroundings
