Q: In multicellular organisms, mutations can be subdivided into germline mutations and? Read this paragraph and choose the correct option from the provided answers: Once again, a mutation is the change in the DNA or RNA sequence. In multicellular organisms, mutations can be subdivided into germline mutations and somatic mutations. Germline mutations occur in the DNA of sex cells, or gametes, and are therefore potentially very serious. These mutations can be passed to the next generation. If the zygote contains the mutation, every cell in the resulting organism will have that mutation. If the mutation results in a disease phenotype, the mutation causes what is called a hereditary disease. Somatic mutations , which occur in somatic, or body, cells, cannot be passed to the next generation (offspring). Mutations present in a somatic cell of an organism will be present (by DNA replication and mitosis) in all descendants of that cell. If the mutation is present in a gene that is not used in that cell type, the mutation may have no effect. On the other hand, the mutation may lead to a serious medical condition such as cancer. Choices: - elective mutations - comparative mutations - resultant mutations - somatic mutations A:
somatic mutations

Q: What allows theories to be widely accepted? Read this paragraph and choose the correct option from the provided answers: The term theory is used differently in science than it is used in everyday language. A scientific theory is a broad explanation that is widely accepted because it is supported by a great deal of evidence. Because it is so well supported, a scientific theory has a very good chance of being a correct explanation for events in nature. Because it is a broad explanation, it can explain many observations and pieces of evidence. In other words, it can help connect and make sense of many phenomena in the natural world. Choices: - hypothesis - observation - theory - evidence A:
evidence

Q: Q: What nucleic acid stores the genetic information? Read this paragraph and choose the correct option from the provided answers: Nucleic acids are large polymers formed by linking nucleotides together and are found in every cell. Deoxyribonucleic acid (DNA) is the nucleic acid that stores genetic information. If all the DNA in a typical mammalian cell were stretched out end to end, it would extend more than 2 m. Ribonucleic acid (RNA) is the nucleic acid responsible for using the genetic information encoded in DNA to produce the thousands of proteins found in living organisms. Choices: - Nucleus - Ribosomes - molecule - dna A:
A: dna

Question: Q: Over time, what changes solid rock into pieces? Read this paragraph and choose the correct option from the provided answers: Weathering changes solid rock into pieces. These pieces are called sediments. Sediments are described in the chapter Earth's Materials and Crust . Sediments are different sizes of rock particles. Boulders are sediments; so is gravel. At the other end, silt and clay are also sediments. Weathering may also cause the minerals at the Earth's surface to change form. The new minerals that form are stable at the Earth's surface. There are two types of weathering, mechanical and chemical. These are discussed in the next two concepts. Choices: - metamorphosis - creep - leaching - weathering A:
Answer: weathering

Q: Name an important natural resource in and of itself. Read this paragraph and choose the correct option from the provided answers: It's obvious that living things are important natural resources needed by human beings. After all, other species provide us with all of the food we eat. We couldn't survive without them. But that's far from the only reason that other species are important for human survival. Biodiversity is an important natural resource in and of itself. Choices: - habitat - food chain - water - biodiversity A:
**Answer**
biodiversity

Q: What forms after air cools below its dew point? Read this paragraph and choose the correct option from the provided answers: Advection fog is famous in San Francisco, California. Warm, moist air comes in from the Pacific Ocean. The air blows over the cold California current. When the air cools below its dew point, fog forms. Sea breezes bring the fog onshore. Choices: - sleet - smoke - plasma - fog A:
**Answer**
fog
