A plastic bag is an everyday object that behaves like an animal cell. The bag itself represents the plasma membrane of a cell, while the items inside the bag represent the different organelles, each with its distinct function.
An everyday object that acts like an animal cell could be a plastic bag. Let me explain why. The plastic bag acts like the plasma membrane, which is the outer lining of an animal cell. It holds everything inside, much like the way a plastic bag holds whatever you put into it. Then, you have your belongings inside the bag resembling the organelles, the functional components of an animal cell. Each item in the bag has a different purpose, similar to how each organelle in a cell has a unique function.

Answer:
The correct answer is option a. "recoil of the lungs".
Explanation:
Normal respiration is passive, which means that no energy is needed to release the air from the lungs. Passive respiration is preceded by the recoil of the lungs that happens without any effort because of the elasticity of the lungs tissue. After inspiration, the diaphragm and intercostal muscles relax and the thoracic cavity and lungs decrease in volume. This causes that the interpulmonary pressure rises above atmospheric pressure, creating an air pressure gradient that put the air out of the lungs without the need of energy.
