Answers

Answer 1

Answer:

Answer:

A. Used to find extraterrestrial life, size and area of a planet / star.

Explanation:

Drake equation is the probability argument used to estimate the number of active, extraterritorial civilizations in a milky way or number of communicating civilizations in the cosmos or more simply put, the odds of finding intelligent life in the universe.

Life existing on earth is due to the habitable zone.The region on the solar system where the temperature is in this range, is called the habitable zone. if a planet is too far away, the atmosphere will be cold and dry, and Carbon levels will remain high to the point that they would be toxic to Earth animals.

Melissa is surprised because she thought the water would extinguish the flame rather than ignite it further. Her mother tells her that the water might be contaminated with dissolved methane, a primary component in natural gas. Melissa investigates the matter and finds that cases of methane contamination started shortly after a company began fracking for natural gas in the area. Based on this information, which three statements are plausible consequences of fracking in Greendale?Fracking contributed to methane finding its way into the residential water supply.

Fracking is always safe to use in the proximity of Greendale's water supply.
