(a) Todescribe: The ways in which the nervous system detects and responds to a decrease in blood pressure. Introduction: Blood pressure is the pressure of blood exerted on the walls of the vessels. More salt content present in the blood, higher will be the blood pressure and vice versa. Diabetes, high cholesterol, and stress are some of the causes of high blood pressure. Diuretics are also used in lowering high blood pressure.

The ways in which the nervous system detects and responds to a decrease in blood pressure.

Introduction:

Blood pressure is the pressure of blood exerted on the walls of the vessels. More salt content present in the blood, higher will be the blood pressure and vice versa.

To describe:

The ways in which the nervous system detects and responds to an increase in blood carbon dioxide level.

Introduction:

Nervous system is a network of nerve cells that have occupied the whole body. The nervous system consisted of the brain, spinal cord, and all the nerves that connect these organs to the whole body.

Summary Introduction

(c)

To describe:

The ways in which the nervous system detects and responds to a decrease in blood pH.

Introduction:

The pH of a solution is measured by the amount of H+ ions present in it. The solutions with more H+ ions have a lower pH while the solutions with less H+ ions have high pH. Any increase in the concentration of H+ ions decreases the pH. However, the decrease in the concentration of H+ ions increases the pH.

Summary Introduction

(d)

To describe:

The ways in which the nervous system detects and responds to a decrease in blood oxygen level.

Introduction:

The circulatory system is composed of many blood vessels that carry blood from one body part to another. Arteries are the blood vessels that transport oxygenated blood across the body.

Question #3: In the KeyGene paper, the authors state that it would be useful if pollen from an apomict would transmit apomixis-inducing genes to the female in the cross (assuming the pollen is viable). Assuming there was just one gene conferring gametophytic obligate apomixis, and that the two parents are inbreds, what would be the consequences of such a cross if: a) The apomixis was a dominant trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the parental cross. b) The apomixis was a recessive trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the…

Question #5: Assume that two genes are identified that confer gametophytic facultative apomixis in soybean. The genes show independent assortment. Recessive alleles at both loci are required for the facultative apomixis. Facultative apomixis is triggered when the temperature at pollination is above 20 degrees C. At temperatures below 20 degrees C, all reproduction is sexual, independent of genotype. A facultative apomict male, capable of producing viable pollen, was crossed with a sexually reproducing female. Assuming the parents are completely inbred, what are the predicted phenotypic ratios (apomict: non-apomict) for the F1, F2, and DH (F1-derived) generations at each of the following temperatures*: a) 15°C? b) 25°C? *for full credit, show crosses and genotypes where appropriate. Remember to position the female first (left side) in the cross. Type your answer here:
