Q: What property does coulomb electric force depend upon? Read this paragraph and choose the correct option from the provided answers: Electromagnetism is associated with charge and is a fundamental force of nature, like gravity. If charges are static, the only manifestation of electromagnetism is the Coulomb electric force. In the same way that gravitational force depends on mass, the Coulomb electric force depends on the property known as electric charge. Like gravity, the Coulomb electric Force decreases with the square of the distance. The Coulomb electric force is responsible for many of the forces we discussed previously: the normal force, contact forces such as friction, and so on - all of these forces arise in the mutual attraction and repulsion of charged particles. Choices: - electric case - electric neutral - electric half - electric charge A:
electric charge

Q: An aquifer is an underground layer of rock that is saturated with what? Read this paragraph and choose the correct option from the provided answers: An aquifer is an underground layer of rock that is saturated with groundwater. One of the biggest aquifers in the world is the Ogallala aquifer in the American Midwest. Choices: - ocean water - wastewater - oil - groundwater A:
(Answer)
groundwater

Ques: Q: What is one way of classifying organisms called? Read this paragraph and choose the correct option from the provided answers: One way of classifying organisms that shows phylogeny is by using the clade. A clade is a group of organisms that includes an ancestor and all of its descendants. Clades are based on cladistics. This is a method of comparing traits in related species to determine ancestor-descendant relationships. Clades are represented by cladograms, like the one in Figure below . This cladogram represents the mammal and reptile clades. The reptile clade includes birds. It shows that birds evolved from reptiles. Linnaeus classified mammals, reptiles, and birds in separate classes. This masks their evolutionary relationships. Choices: - cluster - tuck - spasm - clade A:
Ans: clade

Q: The pituitary gland is called the "master gland" of what system? Read this paragraph and choose the correct option from the provided answers: The pea-sized pituitary gland is just below the hypothalamus and attached directly to it. The pituitary receives hormones from the hypothalamus. It also secretes its own hormones. Most pituitary hormones control other endocrine glands. That's why the pituitary gland is called the "master gland" of the endocrine system. Table below lists several pituitary hormones and what they do. Choices: - hormonal - digestive - nervous - endocrine A:
(A).
endocrine

Ques:Q: What process allows plants to convert light energy into sugars and energy for food? Read this paragraph and choose the correct option from the provided answers: Chemical reactions are occurring all around you. Plants use sunlight to drive their photosynthetic process and produce energy. Cars and other vehicles burn gasoline in order to power their engines. Batteries use electrochemical reactions to produce energy and power many everyday devices. Many chemical reactions are going on inside you as well, especially during the digestion of food. Choices: - respiration - glycolysis - digestion - photosynthesis A:

Ans:photosynthesis

Q: What occurs in a population when its allele frequencies change over time? Read this paragraph and choose the correct option from the provided answers: Evolution occurs in a population when its allele frequencies change over time. For example, the frequency of the A allele might change from 0.7 to 0.8. If that happens, evolution has occurred. What causes allele frequencies to change? The answer is forces of evolution. Choices: - variation - generation - extinction - evolution A:
evolution
