Answer the following question given this paragraph: Power is the rate at which energy is being transferred. Power tells you how many Joules per second of energy is being used to drive something. Thus power is simply the change in energy divided by the time. Since work is by definition the transfer of energy (in or out of a system), power is also equal to the work divided by the time. Efficiency tells you how efficient something is and gives a number between 0 and 1. If the efficiency is equal to 1, then the machine is perfectly efficient (that is all the power used to drive it goes to the out put of the machine with no energy losses). If the efficiency is zero, then all of the input power is lost in the machine and the machine can not output any energy. Q: What is the rate at which energy is being transferred called? A:
OPTIONS:
- electric
- force
- pressure
- power
power

Answer the following question given this paragraph: Telescopes on Earth all have one big problem: Incoming light must pass through the atmosphere. This blocks some wavelengths of radiation. Also, motion in the atmosphere distorts light. You see this when you see stars twinkling in the night sky. Many observatories are built on high mountains. There is less air above the telescope, so there is less interference from the atmosphere. Space telescopes avoid such problems completely since they orbit outside the atmosphere. Q: Space telescopes avoid such problems completely since they orbit outside the what? A:
OPTIONS:
- ozone layer
- galaxy
- earth's crust
- atmosphere

Answer: atmosphere

Question: Answer the following question given this paragraph: Sexual Reproduction Sexual reproduction is the combination of (usually haploid) reproductive cells from two individuals to form a third (usually diploid) unique offspring. Sexual reproduction produces offspring with novel combinations of genes. This can be an adaptive advantage in unstable or unpredictable environments. As humans, we are used to thinking of animals as having two separate sexesmale and femaledetermined at conception. However, in the animal kingdom, there are many variations on this theme. Hermaphroditism Hermaphroditism occurs in animals where one individual has both male and female reproductive parts. Invertebrates such as earthworms, slugs, tapeworms and snails, shown in Figure 43.5, are often hermaphroditic. Hermaphrodites may selffertilize or may mate with another of their species, fertilizing each other and both producing offspring. Self fertilization is common in animals that have limited mobility or are not motile, such as barnacles and clams. Q: Sexual reproduction is the combination of (usually haploid) reproductive cells from two individuals to form a third (usually diploid) unique offspring. sexual reproduction produces offspring with novel combinations of what? A:
OPTIONS:
- features
- cells
- phenotypes
- genes
Answer: genes

input with options: Answer the following question given this paragraph: The bottom of the ocean is called the benthic zone. It includes the sediments on the bottom of the ocean and the water just above it. Organisms living in this zone include clams and crabs. They may be few in number due to relatively scarce nutrients in this zone. Q: The bottom of the ocean is called what? A:
OPTIONS:
- Intertidal zone
- Final zone
- Demersal zone
- the benthic zone
output: the benthic zone

Q: Answer the following question given this paragraph: Giant tube worms are found at hydrothermal vents. They get food from the chemosynthetic bacteria that live within them. The bacteria provide food; the worms provide shelter. Q: What type of vents are giant tube worms found at? A:

OPTIONS:
- Heated
- oxygen
- temperature
- hydrothermal

A: hydrothermal

Answer the following question given this paragraph: Without weathering, we would not have any soil on Earth. People could not live on Earth without soil! Your life and the lives of most organisms depend on soil. Soil is only a very thin layer over solid rock. Yet, it is the place where reactions between solid rock, liquid water and air take place. We get wood, paper, cotton, medicines, and even pure water from soil. So soil is a very important resource. Our precious soil needs to be carefully managed and cared for. If we don't take care of the soil we have, we may not be able to use it in the future. Q: Weathering is fundamental to the creation of what, which exists as a very thin layer over solid rock? A:
OPTIONS:
- fungus
- moss
- aquifers
- soil
soil
