Explanation:
In a covalent bond, there is sharing of the donated electron by two atomic species having very small electronegative differences between them. 
Oxidation is the loss of electrons by a specie and it usually lead to an increase in oxidation number. 
 Reduction is the gain of electrons by a specie. It leads to a lower oxidation number. 
Since there is no actual loss of gain of electrons in a covalent body, the electronegativiy is at work. 
Electronegativity is the ability of a specie to draw the shared electrons more to itself in a covalent bond. 
- Between two atoms bonded covalently, the more electronegative specie draws the electrons closer. 
- This leaves a partial negative charge on it. 
- The other electron then becomes partially positively charged. 
- We can then say, the more electronegative specie undergoes reduction. 
- The less electronegative one undergoes oxidation.

Answer:
0%
Explanation:
Round = Dominant
Wrinkled = recessive
Recessive = r
Dominant = R
homozygous dominant = RR
homozygous recessive = rr
Heterozygous= Rr
Since both seeds are homozygous recessive (rr) 
In your punnet square, one lower case r will go on the top and the left side 
      r    r
r
r
Something like that.
Go across your four boxes and you will end up with;
rr, rr
rr, rr
In order for it to be round, at least one box would need to have to be a heterozygous(Rr) or be a homozygous dominant.
 
        
             
        
        
        
Answer:
27.5
Explanation:
Divide 75 by 6. You get 12.5. Multiply 12.5 by 2.2 (when converting kilo to pound, you multiply by 2.2) Then, you'll get 27.5. The answer is 27.5 pounds/lbs.
 
        
             
        
        
        
The carbon cycles recycles caronatoms(carbon dioxide) and the nitrogen cycle recycles nitrogen.and the carbon cycle makes carbon dioxide and the carbon dioxide goes to the trees ,and the trees get the nitrogen and starts the cycle again.
