Answer:
The main difference between eukaryotic and prokaryotic cells is that eukaryotic cells have a nucleus. 
The nucleus is where cells store their DNA, which is the genetic material. 
The nucleus is surrounded by a membrane. ... 
Explanation:
All prokaryotes are single-celled (unicellular) organisms.

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's metabolic activities
        
             
        
        
        
Answer:
i think White Dwarf
Explanation:
We are given that the star has a temperature of 10,000 K and a luminosity of 10^2. According to the HR diagram, a star with the surface temperature of 10,000 K would be a white dwarf and if the star were on the main sequence, then it would have a luminosity nearly 100 times more than that of the sun. However since the actual luminosity is 10,000 times smaller than this, this star must be a white dwarf since it has 10,000 K and 100 aka 10^2 luminosity
 
        
             
        
        
        
Most of the carbon in the earth is stored in the soil and air.
A) soil and air
<u>Explanation:</u>
Most of the carbon on earth is stored in rocks in the soil. There is approximately 2500 billion tons of carbon in the soil. The amount of carbon in the air is 800 billion tons and the amount of carbon found in plants and animals is 560 billion tons.
This clearly tells that most of the carbon in earth is stored in soil and air. The movement of carbon within the biosphere makes up the carbon cycle.
