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.

The MOST distinctive feature of ape dentition, which clearly distinguishes apes from Old World monkeys, is
Ugo [173]

The most distinctive feature of ape dentition, which clearly distinguishes apes from Old World monkeys, is a Y-5 molar pattern.

<h3>What is the Y-5 molar pattern?</h3>
  • This is a distinctive type of molar teeth pattern found in apes and hominoids.
  • In this, 5 cusps or raised surfaces are present on the grinding surface of teeth, roughly forming a Y- shape. Therefore, this is also known as Y-5 pattern.
  • Whereas Old world monkeys have only 4 cusps on their lower molars present in a bilophodont pattern.
  • A Y-5 molar is formed when the tooth is divided into different pieces which form the complete structure of the tooth.
  • In bilophodont pattern the tooth is divided into 2 symmetric sections.
  • The dental formula of apes is 2.1.2.3/2.1.2.3 i.e. 2 incisors, 1 canine, 2 premolars, 3 molars.

Licemer1 [7]

When cells makes a new compound, such as glycogen from many glucose molecules, usable energy is needed and is obtained by removing a phosphate group from ATP, producing energy plus ADP plus phosphate.

<h3>What is ATP?</h3>

This is referred to as adenosine triphosphate and is the energy currency of the cells.

This is  usually formed from the synthesis of ADP and a phosphate group thereby making it the most appropriate choice.
