Answer the following question given this paragraph: A: A can of warm soda will fizz more because increasing the temperature decreases the solubility of a gas. Therefore, less carbon dioxide can remain dissolved in warm soda than in cold soda. Q: A can of warm soda will fizz more because increasing the temperature decreases the what of a gas? Choices: - Acidity - humidity - viscosity - solubility A:
solubility
Answer the following question given this paragraph: Some of the best known types of fungi are mushrooms, which can be edible or poisonous ( Figure below ). Many species are grown commercially, but others are harvested from the wild. When you order a pizza with mushrooms or add them to your salad, you are most likely eating Agaricus bisporus , known as white or button mushrooms, the most commonly eaten species. Other mushroom species are gathered from the wild for people to eat or for commercial sale. Many mushroom species are poisonous to humans. Some mushrooms will simply give you a stomachache, while others may kill you. Some mushrooms you can eat when they are cooked but are poisonous when raw. So if you find mushrooms in the wild, don't eat them until you are certain they are safe!. Q: Mushrooms are an example of what type of organism, which includes beneficial and toxic specimens? Choices: - spores - bacteria - seeds - fungi A:
fungi

Answer the following question given this paragraph: 19.2 Population Genetics Both genetic and environmental factors can cause phenotypic variation in a population. Different alleles can confer different phenotypes, and different environments can also cause individuals to look or act differently. Only those differences encoded in an individual's genes, however, can be passed to its offspring and, thus, be a target of natural selection. Natural selection works by selecting for alleles that confer beneficial traits or behaviors, while selecting against those for deleterious qualities. Genetic drift stems from the chance occurrence that some individuals in the germ line have more offspring than others. When individuals leave or join the population, allele frequencies can change as a result of gene flow. Mutations to an individual's DNA may introduce new variation into a population. Allele frequencies can also be altered when individuals do not randomly mate with others in the group. Q: What works by selecting for alleles that confer beneficial traits or behaviors, while selecting against those for deleterious qualities? Choices: - same selection - artificial selection - characteristic selection - natural selection A:
**Answer**
natural selection
