The black coffee, with a pH of 5 has a hydrogen ion concentration of 1 x 10^-5 mol/L. The tomato juice, with a pH of 4, has a hydrogen ion concentration of 1 x 10^-4 mol/L.  
By taking the difference between the two respective concentrations, we can compute how much greater the concentration of hydrogen ions in the tomato juice is compared to the coffee.  
Difference = (1 x 10^-4 mol/L) - (1 x 10^-5 mol/L) 
Difference = 9 x 10^-5 mol/L  
Thus, the tomato juice has a concentration of hydrogen ions that is 0.00009 mol/L greater than the the concentration of hydrogen ions in the black coffee.

Answer:

the number of oxytocin receptors on the cell surface  

Explanation:

The increase of the number of hormone receptors present on the surface of target cells increases the sensitivity of such cells to the hormone. Oxytocin is a neuropeptide hormone produced by the hypothalamus and released by the posterior pituitary gland. This hormone acts as a neurotransmitter that binds to oxytocin receptors in order to trigger a molecular cascade that finalizes with the activation of the enzyme Phospholipase-C. Oxytocin receptors are found in different types of brain cells including, for example, the amygdala and hippocampus (where oxytocin binds). This hormone acts as a chemical messenger that modulates brain functions associated with the reproductive system (i.e., childbirth and lactation) and human behavior.
