Answer:
The answer is B: Active Transport 
Explanation: Because energy is required to move the sodium and potassium ions against the concentration gradient. Sodium ions are actively transported from the inside of the cell to the outside of the cell, even though there is a higher concentration of sodium ions on the outside.
 
        
             
        
        
        
"Cells are so little, so they can maximize their ratio of surface area to volume. Smaller cells have a higher ratio which allow more molecules and ions move across the cell membrane per unit of cytoplasmic volume. Cells are so small because they need to be able to get the nutrients in and the waste out quickly."

That the Red flowers are a dominant trait, and the white flowers would be recessive.  
The Red Flowers are Homogenous Dominant
In a punnet square, The Genotype ratio for the red flowers would be 2:2 
The phenotype would be 4:0 
For the white flower 
The Genotype would be 1:1
and the phenotype would be 1:0 
The white flowers are Homogenous recessive
