Answer the following question given this paragraph: Compounds that contain mainly the elements carbon and hydrogen are called organic compounds . This is because they are found mainly in living organisms. Most organic compounds are held together by covalent bonds. An example of an organic compound is glucose (C 6 H 12 O 6 ), which is shown in Figure below . Glucose is a simple sugar that living cells use for energy. All other compounds are called inorganic compounds. Water is an example of an inorganic compound. Q: Compounds that contain mainly the elements carbon and hydrogen are called what kind of compounds? Choices: - microscopic compounds - reactive compounds - natural compounds - organic compounds A:
organic compounds
Answer the following question given this paragraph: A gene pool is the complete set of unique alleles in a species or population. Mutations create variation in the gene pool. Populations with a large gene pool are said to be genetically diverse and very robust. They are able to survive intense times of natural selection against certain phenotypes. During these times of selection, individuals with less favorable phenotypes resulting from deleterious alleles (due to mutations) may be selected against and removed from the population. Concurrently, the more favorable mutations that cause beneficial or advantageous phenotypes tend to accumulate in that population, resulting, over time, in evolution. In fact, without any change in the gene pool, without any new alleles added due to new mutations, evolution could not occur. Genetic change is the driving force of evolution. In fact, evolution can be genetically defined as the change allele frequencies over time. Q: What increases the size of a population's gene pool? Choices: - mass extinction - microbes - natural selection - mutations A:
mutations
Q: Answer the following question given this paragraph: Some volcanoes form over active hotspots . Scientists count about 50 hotspots on the Earth. Hotspots lie directly above a column of hot rock called a mantle plume . Mantle plumes continuously bring hot rock up from the mantle toward the crust ( Figure below ). The rock melts due to the release of pressure. Q: What is the column of hot rock that continuously brings hot rock up from the mantle toward the crust? Choices: - volcanic vent - hotspot - flue - mantle plume A:
A: mantle plume
Question: Answer the following question given this paragraph: They will all blend together. The dyes will move through the water until an even distribution is achieved. The process of moving from areas of high amounts to areas of low amounts is called diffusion. Q: The process of moving from areas of high amounts to areas of low amounts is called what? Choices: - transfer - deposition - filtration - diffusion A:
Answer: diffusion
