Q: Q: Geysers are created when what is heated beneath the earth's surface? Read this paragraph and choose the correct option from the provided answers: Geysers are also created by water that is heated beneath the Earth's surface. The water may become superheated by magma. It becomes trapped in a narrow passageway. The heat and pressure build as more water is added. When the pressure is too much, the superheated water bursts out onto the surface. This is a geyser . Choices: - magma - gases - air - water A:
A: water

A: segmented

Read this paragraph and choose the correct option from the provided answers: Gas exchange is the movement of oxygen into the blood and carbon dioxide out of the blood. Choices: - naturally dioxide - carbon monoxide - liquid dioxide - carbon dioxide A:
A: carbon dioxide

Q: Q: Genetic diversity in a population comes from two main sources - sexual reproduction and what else? Read this paragraph and choose the correct option from the provided answers: Variation and Adaptation Natural selection can only take place if there is variation, or differences, among individuals in a population. Importantly, these differences must have some genetic basis; otherwise, selection will not lead to change in the next generation. This is critical because variation among individuals can be caused by non-genetic reasons, such as an individual being taller because of better nutrition rather than different genes. Genetic diversity in a population comes from two main sources: mutation and sexual reproduction. Mutation, a change in DNA, is the ultimate source of new alleles or new genetic variation in any population. An individual that has a mutated gene might have a different trait than other individuals in the population. However, this is not always the case. A mutation can have one of three outcomes on the organisms' appearance (or phenotype):. Choices: - radiation - education - pathogen - mutation A:
A: mutation
