Answer the following question given this paragraph: Electromagnetic radiation is energy transmitted as waves with different wavelengths. This makes up the electromagnetic spectrum. Q: What is transmitted that makes up the electromagnetic spectrum? Choices: - gamma rays - light waves of different wavelengths - sound waves of different frequencies - electromagnetic radiation in different wavelengths A:
electromagnetic radiation in different wavelengths
Answer the following question given this paragraph: Ocean water is salty because water dissolves minerals out of rocks. This happens whenever water flows over or through rocks. Much of this water and its minerals flow in rivers that end up in the oceans. Minerals dissolved in water form salts. When the water evaporates, it leaves the salts behind. As a result, ocean water is much saltier than other water on Earth. Q: Water dissolving minerals out of rocks makes ocean water what? Choices: - muddy - bitter - sweet - salty A:
salty
Q: Answer the following question given this paragraph: The elements of the halogen group (Group 17) gain electrons most readily, as can be seen from their large negative electron affinities. This means that more energy is released in the formation of a halide ion than for the anions of any other elements. Considering electron configuration, it is easy to see why. The outer configuration of all halogens is n s 2 n p 5 . The addition of one more electron gives the halide ions the same electron configuration as a noble gas, which we have seen is particularly stable. Q: The addition of electron gives the halide ions the same electron configuration as what gas? Choices: - a flammable gas - a fatty gas - an inert gas - a noble gas A:
A: a noble gas
Question: Answer the following question given this paragraph: Sexual reproduction results in offspring that are genetically unique. They differ from both parents and also from each other. This occurs for a number of reasons. Q: What type of reproduction results in genetically unique offspring? Choices: - mitosis - asexual reproduction - internal reproduction - sexual reproduction A:
Answer: sexual reproduction

Answer the following question given this paragraph: The gene theory states that the characteristics of living things are controlled by genes. Q: Which theory states that the characteristics of living things are controlled by genes? Choices: - string theory - creationism - order theory - gene theory A:
**Answer**
gene theory
Answer the following question given this paragraph: Life on Earth began about 3.5 to 4 billion years ago. The first life forms were single-celled organisms similar to bacteria. The first multicellular organisms did not appear until about 610 million years ago. Many different types of organisms evolved during the next ten million years, in an event called the Cambrian Explosion . This sudden burst of evolution may have been caused by some environmental changes that made the Earth's environment more suitable for a wider variety of life forms. Q: What were the first life forms found on earth similar to? Choices: - mold - ferns - viruses - bacteria A:
bacteria
