Answer:
C. When the chest volume expands, air can now rush in through the puncture without filling the alveoli.
Explanation:
During inhalation, the contraction of the diaphragm and the external intercostals increase the volume of the chest cavity. As the chest cavity expands, the alveolar pressure become lower than the atmospheric pressure resulting in the flow of air into the lungs in response to the pressure gradient.
The chest cavity is an airtight chamber. This ensures that any changes in the volume of are chest cavity corresponds to the volume of the lungs. If a lung is punctured, the air would not fill the punctured lung but would escape through the hole. Therefore, the punctured lung would not be filled with air during inhalation.
Answer:
The physical conditions are necessary for nuclear fusion and formation of stars are given below.
Explanation:
Nuclear fusion emitted high amount of heat energy which increases the temperature of the surrounding environment while formation of stars absorb heat energy and finally lower the temperature. The force of gravitational attraction is lower in nuclear fusion while the force of gravitational attraction becomes higher in formation of stars. Nuclear fusion does not promote stellar formation while formation of stars promotes stellar formation.

Is it an organelle? I honestly don’t know I’m confuzzled why is this so hard for me?! If you get the answer and it’s not organelle, tell me please
Answer:
They were competing for the same type of food.
Explanation:
The introduction of brown and black European rats may have led to the extinction of Darwin’s rice rat due to competition for food and resources. These are the main factors that affects am organisms survival.
The brown and black rat were better adapted for survival and competition of the food and resources available which lead to the death and extinction of Darwin’s rice rat.
