The two subunits in and near the fetal heart that enable most blood to bypass the non-functional lungs. Introduction: In the fetus, the lungs are not yet inflated or functional. So, there is a little point for pumping all the blood through the lungs of the fetus. There, the lungs receive enough blood to meet the metabolic and development needs. However, most of the blood bypasses the pulmonary circuit through two anatomical shortcuts. These are called shunts. One is foramen ovale and the other one is ductus arteriosus.

You do NOT need to submit graphs or data tables. Give the terminal regression line equation and R or R² value: Give the x axis (name and units, if any) of the terminal line: Give the y axis (name and units, if any) of the terminal line: Give the residual regression line equation and R or R² value: Give the x axis (name and units, if any) of the residual line: Give the y axis (name and units, if any) of the residual line:

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.

Name: Date: Investigation: Is a dog more closely related to a coyote or a wolf? Gray Wolf Species Name: Canis lupus Color: Light gray to black Size: 80-120 pounds, 2.5 feet tall Appearance: broad snout, round ears, long tail Coyote Species Name: Canis latrans Color: Light gray to brown Size: 20-50 pounds, 1.5 feet tall Appearance: narrow snout, pointed ears, long tail Dog, Alaskan Malamute Species Name: Canis lupus familiaris Color: Gray and white or brown and white Size: 70-80 pounds, 2 feet tall Appearance: broad snout, round ears, long tail 1. Examine the images and descriptions above. Underline any similarities between the dog and the wolf. Place a star next to any coyote traits that are similar to the dog. 2.
