Answer:
Cell membrane
Explanation:
According to the question, Lauren's diseased condition, which is cystic fibrosis, is characterized by her body's inability to control the flow of salt into and out of her cells leading to symptoms include coughing and wheezing when she tries to exercise.
Lauren's inability to control the movement of salt and water into her cells is as a result of an affected CELL MEMBRANE. The cell membrane is the organelle that controls what goes in and out of a cell due to its semi-permeability.
<span>The ventricles are the part of the heart that are responsible for the pumping action to move blood throughout the body. Therefore, the muscles in the ventricles are much larger and thicker to do their job properly. The atrium only has to pump blood through an open valve (the tricuspid valve) into the right ventricle. There is much less resistance to this flow of blood so much less muscle is needed. </span>
This is a biology worksheet all about it hope this helps
