What is the albedo effect?<br><br> Do you think the earth is warming up?
meriva

Answer: Astronomers define the reflectivity of an object in space using a term called albedo. This is the amount of electromagnetic radiation that reflects away, compared to the amount that gets absorbed.

Explanation: But to answer the "Earth warming up" question, I'd have to say that for over millions of years, Earth's climate has warmed up and cooled down many times. However, today the planet is warming much faster than it has over human history. Global air temperatures near Earth's surface have gone up about 2 degrees Fahrenheit in the last century. However, other evidence suggests that the period of 2,000 to 3,000 million years ago was generally colder and more glaciated than the last 500 million years.

So, yes I do believe that the Earth is warming up but not to explode.

These instructions are stored as a code made up of 4 chemical bases: adenine (A), guanine (G), cytosine (C) and thymine (T). butttttt its simlier to a gene : segment of a DNA molecule (a sequence of bases) Which that'd be A ...  that codes for a particular protein and determines the traits (phenotype) of the individual.
