Summary Introduction

To analyze:

The relationship between the pH of the blood and how the brain sets the breathing rate.

Introduction:

Air exhaled by a person has a different gas composition than air absorbed by a person. The capillaries near the alveoli receive oxygen as a result of inhaling. Carbon dioxide is simultaneously transferred from capillaries to alveoli. But not for carbon dioxide, hemoglobin has a stronger affinity. Hemoglobin gains an increased affinity for oxygen when one carbon monoxide molecule attaches to it. To diffuse into the plasma, carbon dioxide becomes bicarbonate ions.

The Snapdragon is a popular garden flower that comes in a variety of colours, including red, yellow, and orange. The genotypes and associated phenotypes for some of these flowers are as follows: aabb: yellow AABB, AABb, AaBb, and AaBB: red AAbb and Aabb: orange aaBB: yellow aaBb: ? Based on this information, what would the phenotype of a Snapdragon with the genotype aaBb be and why?   Question 21 options:   orange because A is epistatic to B   yellow because A is epistatic to B   red because B is epistatic to A   orange because B is epistatic to A   red because A is epistatic to B   yellow because B is epistatic to A
A sample of blood was taken from the above individual and prepared for haemoglobin analysis. However, when water was added the cells did not lyse and looked normal in size and shape. The technician suspected that they had may have made an error in the protocol – what is the most likely explanation?   The cell membranes are more resistant than normal.   An isotonic solution had been added instead of water.   A solution of 0.1 M NaCl had been added instead of water.   Not enough water had been added to the red blood cell pellet.   The man had sickle-cell anaemia.
