Controlling the synthesis of proteins is the key to controlling the chemical pathways in the cell.
This is because proteins have key roles in many chemical reactions in the cell.
The most important proteins for the chemical reactions in the cell are enzymes.
Enzymes catalyze many chemical reactions, therefore, the control of the enzyme synthesis is a direct way of controlling other chemical reactions in the cell.
        
             
        
        
        
Answer:
ovulation phase
Explanation:
The ovulation phase is the only time during your menstrual cycle when you can get pregnant. You can tell that you're ovulating by symptoms like these: a slight rise in basal body temperature
 
        
                    
             
        
        
        
The average distance is 16,000 km
Converging rate is  10 cm/year
1 km = 100,000 cm
 = 16,000 × 100,000/10 cm/year
= 160,000,000 years
It will then take 160 Million years to collide.
