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: Which of the following statements best supports the hypothesis that viruses can cause cancer?

    A. Cellular DNA has sequences related to viral sequences

    B. Cancerous and normal cells share genetic sequences

    C. Genes that regulate cell division are found in some viruses

    D. Viruses and cancer cells both replicate rapidly

    Answer Explanation

    Cancer is a condition caused by unregulated division of abnormal cells in parts of the body. For a virus to survive in an organism, it must enter into the host’s cell and take control of the cell’s most activities in order to be able to reproduce and replicate.

    Some of the viruses achieve this by inserting their DNA or RNA to that of the host cell. This has a highly likelihood of affecting the DNA or RNA of a host (living organism) which alters their genes, which may lead to host cells becoming cancerous.

    For this reason, viruses can cause cancer because the genes that regulate cell division in host cell are found in some viruses.

  • Q #3: In a certain plant, red flowers are dominant over white flowers. A plant heterozygous for red flowers and a plant with white flowers are crossed. Which of the following is the expected proportion of phenotypes in the next generation?

    A. 3 red, 1 white

    B. 1 white, 3 red

    C. 2 red, 2 white

    D. 4 white

    Answer Explanation

    2 red, 2 white.

    In this cross, the plant heterozygous for red flowers has the genotype Rr (where R represents the dominant red allele and r represents the recessive white allele), while the plant with white flowers has the genotype rr.

    The possible offspring from this cross would have the genotypes Rr (red), Rr (red), rr (white), and rr (white), resulting in a 1:1 ratio of red to white flowers.
