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.

This isn't true. There are numerous factors as to when and why a cell divides; just a little bit of searching will return a great deal of information concerning the why and when.
This is true, but isn't the primary reason that a cell divides; I misinterpreted the question.
Growth and cell size does determine when cell division takes place. In short, the demands of the cell become to great for the DNA contained in the cell. Remember, the DNA contains the genetic code to produce the proteome that is needed to maintain the inter-workings of a cell. When the cell becomes to large, the proteome is not able to meet the requirements of the cell, which leads to division.
The link that I included in the source has a great deal of information concerning this.

Nitrogen-fixing bacteria fix atmospheric nitrogen to ammonia, which can then be taken up by plants.
- The process is called biological nitrogen fixation.
- Rhizobium, Azotobacter, cyanobacteria are some examples of nitrogen-fixing bacteria, which may be free-living or symbiotic.
Answer:
CH3 + 2O2-----> CO2+2H2O
Na+ + Cl- ------> NaCl
4Al + 3O2------> 2Al2O3
N2+ +3H2 ------> 2NH3

Answer:
Speed (c) = wavelength (λ) × frequency (f)
Explanation:
The wavelength denoted by (λ), is the distance between two successive waves. The wavelength of a wave us calculated by using the formula: (λ) = c/f.
Where; λ= wavelength
c= velocity or speed
f= frequency
Based on this, the speed of a wave can be calculated by making (c) the subject of the formula in λ=c/f.
We have; c = λf
Hence, the speed of a wave equals the wavelength (λ) multiplied by the frequency (f).
