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.

Therefore, the Correct Answer is A.

Q #1: Metabolism of proteins Which of the following substances is excreted by sweat glands in response to the breakdown of proteins and the formation of ammonia?

A. Sebum

B. Urea

C. Lysozymes

D. Water

Answer Explanation

Proteins are nitrogen-based compounds, which when broken down release ammonia. Ammonia is a toxic substance to the body, and sebaceous glands coverts it to urea.
Q #2: The ________ circulation picks up oxygen for cellular use and drops off carbon dioxide for removal from the body.

A. pulmonary

B. interlobular

C. respiratory

D. bronchial
Answer Explanation

Our blood flow is separated into two major pathways, listed below:
1. Systemic circulation - this comes from the left side of the heart and pumps blood to all working tissues, including the brain, muscle, heart, and other organs, and then into the right side of the heart.
2. Pulmonary system - this comes from the right side of the heart, and pumps blood to the alveolar sacs within the lungs, and then into the left side of the heart
In pulmonary circulation: The pulmonary artery is a big artery that comes from the heart. It splits into two main branches, and brings blood from the heart to the lungs. At the lungs, the blood picks up oxygen and drops off carbon dioxide.
Q #3: Pathogens Which of the following microorganisms lack their own metabolic pathways and can only reproduce inside of a host cell?

A. Bacteria

B. Viruses

C. Helminths

D. Protozoa

Answer Explanation

The disease-causing microorganisms are known as pathogens, which include bacteria, fungi, protozoa, worms, viruses and prions. These organisms have distinguishing cell structures from each other. The most notable difference between viruses and other pathogens is that viruses lack a metabolism mechanism of their own and ability to produce proteins encoded by their DNA or RNA. However, they viruses rely on machinery of the host cell to produce their proteins and replicate their genomes.
