<span>Lungs take in air, and diffuse (absorb) air into the capillaries of the blood. However, this process is two steps, one for inhalation and one for exhalation. Diffusion takes place in both processes, and serves different purposes. One is to absorb oxygen, the other is to rid co2.</span>
Answer;
-Myelination
Explanation;
-Myelination is the process in which neural fibers are coated with an insulating fatty sheath (called myelin) that improves the efficiency of message transfer.
-Most nerve fibers are surrounded by an insulating, fatty sheath called myelin, which acts to speed up impulses. The myelin sheath contains periodic breaks called nodes of Ranvier. By jumping from node to node, the impulse can travel much more quickly than if it had to travel along the entire length of the nerve fiber.
Chromosomes are structures within cells that contain a persons genes.
Answer:
Plasmolysis
Explanation:
In the image 1 the cell is having sufficient quantity of water leading to a turgid cell.
The image 1 plant cell is in a dilute solution in which water enters into cell from external medium.
The image 2 plant cell is exposed to a solution which is high concentrated solution.
Due to this high concentrated solution the water present in the cell is send out by exosmosis.
Due to loss of water from plant cells the protoplasm in plant cell shrinks in which cell membrane gets separated from cell wall.
This shrinkage of protoplasm by loss of water is called plasmolysis.
