My guess is that you're wanting the formula for respiration (which is basically the opposite of the formula for photosynthesis)?
So on the left (reactant/inputs) side should be: sugar and oxygen
On the right (products/outputs) side should be: 
Carbon dioxide, water, light energy/ATP
        
             
        
        
        
The structure that surrounds the cell membrane of some cells, giving the cell a rigid shape is the cell wall.
 
        
             
        
        
        
In certain organisms, like humans, there are two morphologically distinct types of gametes: (1) the male gamete (i.e. sperm cell) and (2) the female gamete (i.e. ovum). The male gamete is smaller in size and motile whereas the female gamete is several times bigger and non-motile. The haploid condition of the two gametes is essential so that at fertilization during sexual reproduction the integrity of the chromosomal number is maintained throughout generations.
Hope this helps.
 
        
                    
             
        
        
        
Answer: c. the wavelength of both transverse and longitudinal waves is measured parallel to the direction of the travel of the wave.
Explanation:
The wavelength is simply the distance that takes place between two successive troughs fir a particular wave. It is calculated as:
Velocity / Frequency.
From the statement given, the option that is accurate is that the wavelength of both transverse and longitudinal waves is measured parallel to the direction of the travel of the wave.
