Ques: Q: What happens to neutral matter when electrons are transferred between objects? Read this paragraph and choose the correct option from the provided answers: Whenever electrons are transferred between objects, neutral matter becomes charged. For example, when atoms lose or gain electrons they become charged particles called ions. Choices: - osmosis - it stays neutral - it dissolves itself - it becomes charged A:
Ans: it becomes charged

Ques: Q: What laws regulate radiation doses to which people can be exposed? Read this paragraph and choose the correct option from the provided answers: Radiation Protection Laws regulate radiation doses to which people can be exposed. The greatest occupational whole-body dose that is allowed depends upon the country and is about 20 to 50 mSv/y and is rarely reached by medical and nuclear power workers. Higher doses are allowed for the hands. Much lower doses are permitted for the reproductive organs and the fetuses of pregnant women. Inadvertent doses to the public are limited to 1 / 10 of occupational doses, except for those caused by nuclear power, which cannot legally expose the public to more than. Choices: - medical regulation laws - voltage protection laws - dose regulation laws - radiation protection laws A:
Ans: radiation protection laws

Ques: Q: Drinking too much water too fast can lead to what potentially fatal condition, which causes dangerous changes to salt levels? Read this paragraph and choose the correct option from the provided answers: available; if arsenic is an essential trace mineral in human diets, it is probably required on the order of 50 ppb or less. A toxic dose of arsenic corresponds to about 7,000 ppb and higher, which is over 140 times the trace amount that may be required by the body. Thus, arsenic is not poisonous in and of itself. Rather, it is the amount that is dangerous: the dose makes the poison. Similarly, as much as water is needed to keep us alive, too much of it is also risky to our health. Drinking too much water too fast can lead to a condition called water intoxication, which may be fatal. The danger in water intoxication is not that water itself becomes toxic. It is that the ingestion of too much water too fast dilutes sodium ions, potassium ions, and other salts in the bloodstream to concentrations that are not high enough to support brain, muscle, and heart functions. Military personnel, endurance athletes, and even desert hikers are susceptible to water intoxication if they drink water but do not replenish the salts lost in sweat. As this example shows, even the right substances in the wrong amounts can be dangerous!. Choices: - inebriation - osmosis - drowning - water intoxication A:
Ans: water intoxication
