Answer:
Kartegener's disorder
Explanation:
The respiratory tract has cilia which move. Sperms also have a tail that moves. They both have the same protein in their structure called microtubules. There is a disorder in which there is the absence of a part in the microtubule. Dynein arms absent in microtubules. Because the respiratory system and sperm both contain cilia that's why these two systems have a connection and not work properly.
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.
