Why do scientists take lots of measurements and calculate averages?
Dima020 [189]
 Scientists take more than one measurements because they want to make sure that their results are fairly accurate answer, result, or/ and explanation on a subject.

Reason: If a scientist just used one measurement or used even one testing group then in the near future, people might use that ONE measurement or testing group to prove questions. .
   In actuality, using more than one measurements can help you go for a more precise answer. It is better to use more than one measurement or testing group that way you may have a more wide explanation of why something is that way.
   For example, if a person wants to know why a softer ball(like a tennis ball) bounces higher than something like a box then the person will use more than one measurement. This will include the height of the bounce, the volume of the items used, the force of gravity on the object, and some other things.

(Hope this helps you better understand :) )

Create a typewritten paper describing the carbon cycle.
Hitman42 [59]

Answer:

Plants reform the carbon into climatic carbon dioxide into carbon-containing organic compounds, such as sugars, fats, and proteins. Plants take in carbon dioxide by minute openings into their leaves, called stomata. They connect atmospheric carbon with water and produce organic compounds, utilizing energy trapped from sunlight in a method called photosynthesis. The by-product of photosynthesis is oxygen, which plants discharge into the atmosphere by the stomata.

Explanation:

Not positive if I'm right but it's the best answer I've got.
