If the Calvin cycle slows down, THE RATE OF OXYGEN PRODUCTION IN PS II WILL BE REDUCED. 
This is because, the light reaction depends on the dark reaction to occur. If the Calvin cycle slows down, the light cycle will have less ADP and NADP+ to work with and this will slow down the production rate of the photosynthetic reaction.
        
             
        
        
        
<h3>Chemical <u>
bond</u> is the answer. </h3>
Explanation:
A chemically bond is defined as the invisible force between two atoms which together forms a molecule. Chemical bonds are of different types - covalent bond and ionic bond. These bonds are formed between the atoms because of a chemical reaction.
In a chemical reaction, different reaction intermediates are formed which leads to the formation of new forces of attraction between nearby atoms or ions to form new bonds. Thus chemical bonds are formed from chemical reaction. 
 
        
        
        
The petal is dead, yeah their are cells in the petal but the cells are "living". The flower is still alive though.
