radioactivity
(Question)
Answer the following question given this paragraph: In shallow water close to shore, waves start to drag on the bottom of the water. The bottomsbut not the topsof the wave slow down because of friction. This causes the waves to steepen until they break and fall over, carrying water onto the shore as surf. Q: The bottomsbut not the topsof the wave slow down because of what? Choices: - size - vibration - temperature - friction A:
(Answer)
friction
Ques: Answer the following question given this paragraph: Hormonal Regulation of Metabolism Blood glucose levels vary widely over the course of a day as periods of food consumption alternate with periods of fasting. Insulin and glucagon are the two hormones primarily responsible for maintaining homeostasis of blood glucose levels. Additional regulation is mediated by the thyroid hormones. Q: What are the two hormones primarily responsible for maintaining homeostasis of blood glucose levels? Choices: - dopamine and melanin - anabolic and metabolic - insulin and estrogen - insulin and glucagon A:
Ans: insulin and glucagon

Answer the following question given this paragraph: For a fixed amount of gas at constant temperature, the volume is inversely proportional to its pressure. Q: If a fixed amount of gas maintains a perfectly inversely proportional relationship between volume and pressure, then what else must be constant about the gas? Choices: - density - friction - surface tension - temperature A:
(A).
temperature
Ques:Answer the following question given this paragraph: When gas pressure-forces are used to move an object then work is done on the object by the expanding gas. Work can be done on the gas in order to compress it. Q: When gas pressure-forces are used to move an object the work is done on the object by? Choices: - contracting gas - kinetic energy - gravitational pull - expanding gas A:

Ans:expanding gas
Answer the following question given this paragraph: Most reptiles reproduce sexually and have internal fertilization. Males have one or two penises that pass sperm from their cloaca to the cloaca of a female. Fertilization occurs within the cloaca, and fertilized eggs leave the female's body through the opening in the cloaca. In a minority of species, the eggs are retained inside the female's body until they hatch. Then the offspring leave the mother's body through the cloaca opening. Q: How do most reptiles produce? Choices: - occasionally - biologically - asexually - sexually A:
sexually
