Answer the following question given this paragraph: A chemical reaction is a process that changes some chemical substances into others. It involves breaking and forming chemical bonds. Types of chemical reactions include synthesis reactions and decomposition reactions. Q: What is the name of the process that changes some chemical substances into others? Choices: - acid reaction - mixture - hypodermic reaction - chemical reaction A:
chemical reaction
Answer the following question given this paragraph: Lobe-fined fish are currently far fewer in number than ray-finned fish. Their fins, like the one shown in Figure above , contain a stump-like appendage of bone and muscle. There are two groups of lobe-finned fish still alive today: coelacanths and lungfish. Q: What are two types of lobe finned fish? Choices: - sharks and piranha - piranha and pike - moles and lungfish - coelacanths and lungfish A:
coelacanths and lungfish
Q: Answer the following question given this paragraph: Unlike protons and neutrons, which are located inside the nucleus at the center of the atom, electrons are found outside the nucleus. Because opposite electric charges attract each other, negative electrons are attracted to the positive nucleus. This force of attraction keeps electrons constantly moving through the otherwise empty space around the nucleus. The Figure below is a common way to represent the structure of an atom. It shows the electron as a particle orbiting the nucleus, similar to the way that planets orbit the sun. Q: Where are protons and neutrons located? Choices: - radius - electron shell - epidermis - nucleus A:
A: nucleus
Question: Answer the following question given this paragraph: Q: What process can be triggered by a burst of ethylene production in the fruit? Choices: - pickling - hardening - drying - ripening A:
Answer: ripening

Answer the following question given this paragraph: DNA is located in the nucleus. Proteins are made on ribosomes in the cytoplasm. Remember that information in a gene is converted into mRNA , which carries the information to the ribosome. In the nucleus, mRNA is created by using the DNA in a gene as a template. A template is a model provided for others to copy. Q: What are made on ribosomes in the cytoplasm? Choices: - lipids - cells - enzymes - proteins A:
**Answer**
proteins
Answer the following question given this paragraph: Composite volcanoes are also called stratovolcanoes. This is because they are formed by alternating layers (strata) of magma and ash ( Figure below ). The magma that creates composite volcanoes tends to be thick. The steep sides form because the lava cannot flow too far from the vent. The thick magma may also create explosive eruptions. Ash and pyroclasts erupt into the air. Much of this material falls back down near the vent. This creates the steep sides of stratovolcanoes. Q: What is in danger of happening when thick magma is formed? Choices: - focused eruptions - continuous eruptions - earthquakes - explosive eruptions A:
explosive eruptions
