The way muscles aid in inhalation and exhalation. Introduction: The respiratory cycle consists of inhaling and exhaling. Air is breathed IN during inhalation, and the air is breathed OUT during expiration. Normal air conduction occurs from the high-pressure area to the low-pressure area. The lungs are stimulated for inhalation when the pressure inside them is lower than the pressure outside. When the pressure inside the lungs is greater than the pressure outside, exhalation happens.

3. In the tomato, red fruit (O+) is dominant over orange fruit (0), and yellow flowers (W+) are dominant over white flowers (w). A cross was made between true-breeding plants with red fruit and yellow flowers, and plants with orange fruit and white flowers. The F₁ plants were then crossed to plants with orange fruit and white flowers, which produced the following results: a. b. 333 red fruit, yellow flowers 64 red fruit, white flowers 58 orange fruit, yellow flowers 350 orange fruit, white flowers Conduct a chi-square analysis to demonstrate that these two genes DO NOT assort independently. Make sure to interpret the P value obtained from your chi-square test. Calculate and provide the map distance (in map units) between the two genes.
