The life history of RBCs and the mechanism by which the body disposes of old RBCs. Introduction: The body is endowed with mechanisms to detect changes in its internal environment, to antagonize the changes, and to ultimately maintain a fairly constant internal environment. These mechanisms together are termed homeostasis – the maintenance of a constant internal environment. To maintain a constant RBC number in blood, the body uses a negative feedback mechanism involving detection of a fall in RBC numbers by the kidneys, which release erythropoietin (EPO) to increase RBC numbers.

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.
