Answer the following question given this paragraph: 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. Q: What property does coulomb electric force depend upon? Choices: - electric case - electric neutral - electric half - electric charge A:
electric charge

Answer the following question given this paragraph: Water pollution happens when contaminants enter water bodies. Contaminants are any substances that harm the health of the environment or humans. Most contaminants enter the water because of humans. Surface water (river or lake) can be exposed to and contaminated by acid rain, storm water runoff, pesticide runoff, and industrial waste. This water is cleaned somewhat by exposure to sunlight, aeration, and microorganisms in the water. Groundwater (private wells and some public water supplies) generally takes longer to become contaminated, but the natural cleaning process also may take much longer. Groundwater can be contaminated by disease-producing pathogens, careless disposal of hazardous household chemical-containing products, agricultural chemicals, and leaking underground storage tanks. Q: What "kind" of water may take longer to become contaminated than surface water, while the natural cleaning process may take longer? Choices: - lake water - spring water - dam water - groundwater A:
(Answer)
groundwater
Ques: Answer the following question given this paragraph: heterotroph that eats only or mainly plants. Q: The heterotroph eats only or mainly what? Choices: - animals - roots - decomposers - plants A:
Ans: plants
(Q).
Answer the following question given this paragraph: This chart shows the genetic code used by all organisms. For example, an RNA codon reading GUU would encode for a valine (Val) according to this chart. Start at the center for the first base of the three base codon, and work your way out. Notice that more than one codon may encode for a single amino acid. For example, glycine (Gly) is encoded by a GGG, GGA, GGC, and GGU. Notice there are 64 codons. Of the 64 codons, three are stop codons. Q: An rna codon reading guu encodes for what? Choices: - glycine - carbon - arginine - valine A:
(A).
valine
Ques:Answer the following question given this paragraph: Q: What can damage animal tissues? Choices: - wind erosion - nervous stress - acid and water exposure - extreme pressure or temperature A:

Ans:extreme pressure or temperature
Answer the following question given this paragraph: Figure 11.13 Muscles of the Anterior Neck The anterior muscles of the neck facilitate swallowing and speech. The suprahyoid muscles originate from above the hyoid bone in the chin region. The infrahyoid muscles originate below the hyoid bone in the lower neck. Q: The anterior muscles of the neck facilitate swallowing and what else? Choices: - hearing - crying - perspiration - speech A:
speech
