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:
**Answer**
water

Q: Abnormally high activity or low activity of the parathyroid gland can cause disorders related to levels of what bone mineral? Read this paragraph and choose the correct option from the provided answers: Abnormally high activity of the parathyroid gland can cause hyperparathyroidism, a disorder caused by an overproduction of PTH that results in excessive calcium reabsorption from bone. Hyperparathyroidism can significantly decrease bone density, leading to spontaneous fractures or deformities. As blood calcium levels rise, cell membrane permeability to sodium is decreased, and the responsiveness of the nervous system is reduced. At the same time, calcium deposits may collect in the body's tissues and organs, impairing their functioning. In contrast, abnormally low blood calcium levels may be caused by parathyroid hormone deficiency, called hypoparathyroidism, which may develop following injury or surgery involving the thyroid gland. Low blood calcium. Choices: - potassium - collagen - magnesium - calcium A:
**Answer**
calcium

Q: Which scientist was responsible for the theory of evolution by natural selection? Read this paragraph and choose the correct option from the provided answers: Linnaeus classified organisms based on obvious physical traits. Basically, organisms were grouped together if they looked alike. After Darwin published his theory of evolution in the 1800s (discussed in the following chapter), scientists looked for a way to classify organisms that showed phylogeny. Phylogeny is the evolutionary history of a group of related organisms. It is represented by a phylogenetic tree , like the one in Figure below . Choices: - stephen hawking - galileo Galilei - albert einstein - charles darwin A:
**Answer**
charles darwin
