Answer the following question given this paragraph: They will all blend together. The dyes will move through the water until an even distribution is achieved. The process of moving from areas of high amounts to areas of low amounts is called diffusion. Q: The process of moving from areas of high amounts to areas of low amounts is called what? Choices: - transfer - deposition - filtration - diffusion A:
diffusion
Answer the following question given this paragraph: On the left side of the electromagnetic spectrum diagram are radio waves and microwaves. Radio waves have the longest wavelengths and lowest frequencies of all electromagnetic waves. They also have the least amount of energy. Q: Of all the electromagnetic waves, which have the lowest frequencies? Choices: - X-rays - ultraviolet rays - gamma rays - radio waves A:
radio waves
Q: Answer the following question given this paragraph: Q: What occurs before the endometrium thickens in estrous cycles? Choices: - fertilization - pregnancy - copulation - ovulation A:
A: ovulation
Question: Answer the following question given this paragraph: Both of these people are participating in a board sport, but the man on the left is snowboarding in Norway while the woman on the right is sandboarding in Dubai. Snow and sand are both kinds of matter, but they have different properties. What are some ways snow and sand differ? One difference is the temperature at which they melt. Snow melts at 0C, whereas sand melts at about 1600C! The temperature at which something melts is its melting point. Melting point is just one of many physical properties of matter. Q: The temperature at which something melts is refered to as what? Choices: - precipitation point - evaporation point - boiling point - melting point A:
Answer: melting point

Answer the following question given this paragraph: Feathers help birds fly and also provide insulation and serve other purposes. Birds actually have two basic types of feathers: flight feathers and down feathers. Both are shown in Figure below . Flight feathers are long, stiff and waterproof. They provide lift and air resistance without adding weight. Down feathers are short and fluffy. They trap air next to a bird's skin for insulation. Q: What two basic types of feather does a bird have? Choices: - carrying and down - up and down - flight and landing - flight and down A:
**Answer**
flight and down
Q: Answer the following question given this paragraph: Most of the body's resistance is in its dry skin. When wet, salts go into ion form, lowering the resistance significantly. The interior of the body has a much lower resistance than dry skin because of all the ionic solutions and fluids it contains. If skin resistance is bypassed, such as by an intravenous infusion, a catheter, or exposed pacemaker leads, a person is rendered microshock sensitive. In this condition, currents about 1/1000 those listed in Table 20.3 produce similar effects. During open-heart surgery, currents as small as 20 A can be used to still the heart. Stringent electrical safety requirements in hospitals, particularly in surgery and intensive care, are related to the doubly disadvantaged microshock-sensitive patient. The break in the skin has reduced his resistance, and so the same voltage causes a greater current, and a much smaller current has a greater effect. Q: What is lowered when salts go into ion form? Choices: - charge - voltage - power - resistance A:
A: resistance
