Q: Answer the following question given this paragraph: Coral reefs ( Figure below ) look like big rocks, but they are actually alive. They are built from cnidarians called corals. The corals are sessile (non-moving) polyps that can use their tentacles to feed on ocean creatures that pass by. Their skeletons are made up of calcium carbonate, which is also known as limestone. Over long periods of time, their skeletons build on each other to produce large structures known as coral reefs. Coral reefs are important habitats for many different types of ocean life. Q: Although they look like big rocks, what structures that serve as habitats for many different types of ocean life are actually alive? A:

OPTIONS:
- new forming reefs
- natural reefs
- southern reefs
- coral reefs

A: coral reefs

input: OPTIONS:
- anus
- oral cavity
- urethra
- cloaca Now, answer this question: Answer the following question given this paragraph: All amphibians have digestive, excretory, and reproductive systems. All three of these organ systems use a single body cavity, called the cloaca. Wastes enter the cloaca from the digestive and excretory systems. Gametes enter the cloaca from the reproductive system. A single external opening in the cloaca allows the wastes and gametes to exit the body. (Many other four legged vertebrates also have a cloaca. ). Q: An external opening in the what of amphibians allows wastes and gametes to exit the body? A:
A:
output: cloaca

Answer the following question given this paragraph: The nucleus of many cells also contains a central region called the nucleolus . The job of the nucleolus is to build ribosomes. These ribosomes flow out the nuclear pores into the cytoplasm. Ribosomes are organelles that make proteins in the cytoplasm. See the composition of the nucleus pictured below ( Figure below ). Q: The job of the nucleolus is to build what? A:

OPTIONS:
- chromosomes
- electrons
- cells
- ribosomes

Answer: ribosomes

Problem: OPTIONS:
- reaction circle
- mechanical mechanism
- basic reaction
- reaction mechanism
Q: Answer the following question given this paragraph: The overall balanced equation for a chemical reaction does not always tell us how a reaction actually proceeds. In many cases, the overall reaction takes place in a series of small steps. An elementary step (or elementary reaction) is one step in a series of simple reactions that show the progress of a reaction at the molecular level. In terms of collision theory, each elementary step corresponds to a single collision. A reaction mechanism is the sequence of elementary steps that together comprise an entire chemical reaction. As an analogy, consider the route that you might take while driving to the grocery store. That route may consist of several turns, similar to the elementary steps. The overall reaction specifies only the beginning point (your house) and the final destination (the store), with no information about the specifics in between. Q: What is the sequence of elementary steps that together comprise an entire chemical reaction called? A:
Answer: reaction mechanism

Answer the following question given this paragraph: To measure very small masses, scientists use electronic balances, like the one in the Figure below . This type of balance also makes it easier to make accurate measurements because mass is shown as a digital readout. In the picture, the balance is being used to measure the mass of a white powder on a plastic weighing tray. The mass of the tray alone would have to be measured first and then subtracted from the mass of the tray and powder together. The difference between the two masses is the mass of the powder alone. Q: What instrument, with a digital readout, is used by scientists to measure very small masses? A:

OPTIONS:
- mixed balance
- mechanical balance
- common balance
- electronic balance

Answer:
electronic balance
