When a plant has grown enough to reproduce it has reached what stage of its life

During the flowering period, plants put all their energy towards reproduction. Different plants may differ in the manner they reproduce. Some seeds will only develop once pollinated by a male plant. In other cases, the female plant will continue to produce more flowers in an effort to reproduce until fertilization  In other plants, seeds will develop during the flowering stage without the need for pollination or fertilization

Explanation:

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles

is there multiple choice answers?
