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.
Troponin-tropomyosin molecules prevents a muscle contraction from occurring when the muscle is at rest.
<h3>What is
muscle contraction?</h3>
The activation of tension-producing regions within muscle cells results in muscular contraction. Because muscle tension can be created without changes in muscle length, such as when holding something heavy in the same position, muscle contraction does not always imply muscle shortening in physiology. Muscle relaxation, or the return of the muscular fibers to their low tension-generating state, occurs after a muscle contraction has finished.
Both length and tension can be used to characterize muscle contractions. If the muscle tension varies but the muscle length doesn't, the muscle contraction is said to be isometric. A muscle contraction is isotonic, however, if the tension in the muscle remains constant during the contraction.

Explanation:
Hey, there!
The eco-system consists of various type of organisms in tge ecosystem. The all type of organism as producer, decomposer, consumers live in ecosystem.
Three adaptations of organism are:
- By losing and gaining of organs: Some of the animals lose their organs to survive in some places like yak have more hair to survive in cold places.
- By changing the colour of body: Some animals such as grasshopper changes their colour to survive in places.
- By modification of organs: some animals modify their organs to survive such as legs and beak of ducks are modified to survive in swim and search foods.
The importance of adaptation are:
- It helps organism to live a longer life.
- The adaptation helps to make an organism fittest to any environment.
- The adaptation helps an organism to search foods and live their life.
