They are called cotyledons
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.
Counter current involves blood in the capillaries flowing in the opposite direction to the flow of water flowing over them. Gases diffuse faster from one area to another when the concentration difference between the two areas is at its greatest, as compared to when the concentration difference is low.
kinetic energy
The energy associated with an object's motion is called kinetic energy. A speeding bullet, a walking person, and electromagnetic radiation like light all have kinetic energy. Another example of kinetic energy is the energy associated with the constant, random bouncing of atoms or molecules.
