Answer the following question given this paragraph: Pressure Associated with the Lungs The pressure inside the lungs increases and decreases with each breath. The pressure drops to below atmospheric pressure (negative gauge pressure) when you inhale, causing air to flow into the lungs. It increases above atmospheric pressure (positive gauge pressure) when you exhale, forcing air out. Lung pressure is controlled by several mechanisms. Muscle action in the diaphragm and rib cage is necessary for inhalation; this muscle action increases the volume of the lungs thereby reducing the pressure within them Figure 11.39. Surface tension in the alveoli creates a positive pressure opposing inhalation. (See Cohesion and Adhesion in Liquids: Surface Tension and Capillary Action. ) You can exhale without muscle action by letting surface tension in the alveoli create its own positive pressure. Muscle action can add to this positive pressure to produce forced exhalation, such as when you blow up a balloon, blow out a candle, or cough. Q: During what phase of breathing does the pressure inside the lungs drops to below atmospheric pressure? Choices: - conduction - exhalation - ingestion - inhalation A:
inhalation

Q: Answer the following question given this paragraph: Hemophilia is a sex-linked trait. Carrier mothers can pass along the affected allele to 50% of their sons. Females with hemophilia would have to receive an affected allele from each parent, making females with hemophilia rare. Q: What disease is given as an example of a sex-linked trait? Choices: - arthritis - hypertension - emphysema - hemophilia A:
A: hemophilia

Answer the following question given this paragraph: The most basic division of living plants is between nonvascular and vascular plants. Vascular plants are further divided into seedless and seed plants. Seed plants called gymnosperms produce seeds in cones. Seed plants called angiosperms produce seeds in the ovaries of flowers. Q: What are the two divisions of vascular plants? Choices: - root and seed - seedless and semi-seeded - aquatic and terrestrial - seedless and seed A:
(Answer)
seedless and seed
