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.

Answer:
The balloon will expand or explode (with enough time)
Explanation:
Charles law states that the volume of a fixed gas is directly proportional to the temperature and pressure. The higher the temperature, the higher the pressure. This will raise the volume, causing the balloon to expand at the very least.
