<span>Diploid number 4 implies 2n = 4. At the end of the meiosis prophase, chromatin condenses into two rod shaped structures called chromosomes, in which they become visible. The nucleolus disappears, the mitotic spindle forms, and the nuclear envelope disappears. The chromosomes are replicated forming two sister chromatids. In the end there are 8 chromatids.</span>
        
             
        
        
        
A molecule is the smallest particle of a substance that exists independently. Molecules of most elements are made up of only one of atom of that element. Oxygen, along with nitrogen, hydrogen, and chlorine are made up of two atoms. ... The oxygen molecules are bonded or stuck together.
 
        
             
        
        
        
Density-dependent limiting factors cause a population's per capita growth rate to change—typically, to drop—with increasing population density. ... Density-independent factors affect per capita growth rate independent of population density. Examples include natural disasters like forest fires.
        
             
        
        
        
<u>Answer:</u> The correct answer is Option c.
<u>Explanation:</u>
Combustion reaction is defined as the chemical reaction in which an organic compound reacts with oxygen gas to produce carbon dioxide gas and water molecule.
This reaction is also known as oxidation reaction.
The chemical equation for the combustion/oxidation of glucose molecule follows:

By Stoichiometry of the reaction:
1 molecule of glucose reacts with 6 molecules of oxygen gas to produce 6 molecules of carbon dioxide gas and 6 molecules of water.
Hence, the correct answer is Option c.
