Q #2: Which of these processes occurs in the mouth?

A. Ingestion

B. Mechanical digestion

C. Chemical digestion

D. All of the above

Answer Explanation

All of these processes occur in the mouth. Ingestion involves taking food into the mouth, mechanical digestion includes the physical breakdown of food through chewing and mixing with saliva, and chemical digestion begins with the action of enzymes in saliva, such as amylase, which starts to break down carbohydrates.
Q #3: Which of the following processes does atmospheric pressure play a role in?

A. Pulmonary Ventilation

B. Photosynthesis

C. Osmosis

D. Evaporation

Answer Explanation

Among the choices provided, only one process is directly influenced by atmospheric pressure:

Pulmonary Ventilation (Correct): Pulmonary ventilation, also known as breathing, is driven by pressure differences between the lungs and the atmosphere. Atmospheric pressure plays a pivotal role in this process by facilitating the movement of air into and out of the lungs.

The other options mentioned in the choices—Photosynthesis, Osmosis, and Evaporation—are not primarily influenced by atmospheric pressure. While atmospheric pressure can indirectly affect certain aspects of these processes, it is not a dominant factor in their mechanisms.
