Explanation:
To find the number of atoms in each specie, we consider the coefficient and the subscript of each of the given atoms. 
1. NaCl: 
Na  = 1 atom
Cl = 1 atom 
2. CO₂
C = 1 atom
O = 2 atom 
3. O₂ 
O = 2 atoms 
4. C₆H₁₂O₆ 
C = 6 atoms 
H = 12 atoms 
O = 6 atoms  
For the second part; 
1. 2NaCl 
Na = 2 atoms 
Cl = 2 atoms 
2. 3CO₂ 
C = 3 atoms 
O = 6 atoms 
3. 4O₂ 
O = 8 atoms 
4. 2C₆H₁₂O₆ 
C = 12 atoms 
H = 24 atoms 
O = 12 atoms

The Answer is 
A. Black box,because black absorbs more heat than white
An example is that on a sunny day you were wearing a black t-shirt you would be sweating you bottom off but if you were wearing a white t-shirt you would be less hot and not sweating your bottom off. Why? Because black absorbs more heat rays than white does
        
                    
             
        
        
        
Answer:
Actually, when two oceanic plates collide, the plate that is older, therefore colder and denser, is the one that will sink. In a contest between a dense oceanic plate and a less dense, buoyant continental plate, you know that it's the dense oceanic plate that sinks.

<span>Somatic mosquito cells have 6 chromosomes. Its gamete has 3 chromosomes. 
</span>
Mosquitoes have 6 number of chromosome but when mosquitoes<span> make sperm or egg </span>cells<span>, meiosis reduces the </span>chromosome<span> number to 3.
</span>
*the chromosome number in somatic body cells of a mosquito --- 6.
<span>the haploid (n) number is 3.
the diploid (2n) number is 6.</span>
