Answer the following question given this paragraph: Q: What kind of relationship between glucagon and insulin is vital to managing fuel storage and consumption by body cells? Choices: - opportunistic - sympathetic - commensalism - antagonistic A:
antagonistic
Answer the following question given this paragraph: The ability of a solute to dissolve in a particular solvent is called solubility . Many chemical substances are soluble in water. In fact, so many substances are soluble in water that water is called the universal solvent. Water is a strongly polar solvent, and polar solvents are better at dissolving polar solutes. Many organic compounds and other important biochemicals are polar, so they dissolve well in water. On the other hand, strongly polar solvents like water cannot dissolve strongly nonpolar solutes like oil. Did you ever try to mix oil and water? Even after being well shaken, the two substances quickly separate into distinct layers. Q: What is known as the universal solvent? Choices: - oil - air - vinegar - water A:
water
Q: Answer the following question given this paragraph: Water waves, sound waves, and the waves that travel along a rope are mechanical waves . Mechanical waves require a material medium such as water, air, or rope. Light waves, however, are electromagnetic waves and travel without a material medium. They are not mechanical waves. Q: What waves require a material medium such as water, air, or rope? Choices: - light - potential - electromagnetic - mechanical A:
A: mechanical
Question: Answer the following question given this paragraph: Q: When does an oocyte complete meiosis? Choices: - metaphase - prophase - anaphase - after sperm penetration A:
Answer: after sperm penetration

Answer the following question given this paragraph: osmol = M i If more than one solute is present in a solution, the individual osmolarities are additive to get the total osmolarity of the solution. Solutions that have the same osmolarity have the same osmotic pressure. If solutions of differing osmolarities are present on opposite sides of a semipermeable membrane, solvent will transfer from the lower-osmolarity solution to the higher-osmolarity solution. Counterpressure exerted on the highosmolarity solution will reduce or halt the solvent transfer. An even higher pressure can be exerted to force solvent from the high-osmolarity solution to the low-osmolarity solution, a process called reverse osmosis. Reverse osmosis is used to make potable water from saltwater where sources of fresh water are scarce. Q: If solutions of differing osmolarities are present on opposite sides of a semipermeable membrane, solvent will transfer from what to what, in terms of osmolarity of the solution? Choices: - low to low - high to high - high to low - low to high A:
**Answer**
low to high
Q: Answer the following question given this paragraph: To understand minerals, we must first understand matter. Matter is the substance that physical objects are made of. Q: What substance are physical objects are made of? Choices: - gravity - energy - friction - matter A:
A: matter
