C) are capable of living independently.
Organelles are NOT capable of living in their own. Cells are the smallest units of life.
Answer:
Five hundred out of every one thousand rats would die
Explanation:
Median lethal dose LD-50 (lethal dose 50%) is used as a measure of poisoning potential of a substance. LD-50 is the dose of substance, given all at once, which causes the death of 50% (one half) of a group of test animals. LD-50 is usually expressed as the amount of chemical administered (e.g., milligrams) per 100 grams or per kilogram of the body weight of the test animal. In this example, the test animals were rats, they were administrated a certain insecticide. Administration methods that are the most common are dermal (applied to the skin) and oral (given by mouth). If the determined LD-50 is 250 milligrams per kilogram of body mass, it means that one half (five hundred) of one thousand rats would die, because we are talking about lethal doses.
There have been 5 mass extinctions in the history of Earth, the main two are the K-T extinction (75% of the world organisms were killed) and the great paleozoic extinction. Scientists believe a massive meteorite caused the KT extinction but could also have been caused by some traps in India. The paleozoic extinction was believed to be caused by traps in Siberia which effected the temperature and atmospheric conditions of the tune
