Not every plant grows from a seed. Some plants, like ferns and mosses, grow from spores. Other plants use asexual vegetative reproduction and grow new plants from rhizomes or tubers. We can also use techniques like grafting or take cuttings to make new plants.
        
             
        
        
        
At STP, 1 mol = 22.4 
1 mol = 6.022 X 10^ 23
so your answer is right it is B 6.022 X 10^ 23
 
        
             
        
        
        
Answer:
200 watts
Explanation:
First we have to find total work:
W =F(d)
W = 400J
Then plug that answer into the Power formula.
P = W/(t_f-t-i)
P = 400/2s
P = 200 W
