Chapter 2.5, Problem 1LO
Summary Introduction

To explain:

The comparison of the structures of fats, phospholipids and sterols.

Introduction:

The fats are composed of triglyceride molecules in the lipid bilayer of the membrane. They are composed of three fatty acid molecules added to the glycerol backbone by the method of condensation. The phospholipids are lipid molecules which have a phosphate group attached. The sterols are cholesterol hydrophobic molecules, which are present on the membrane. These molecules provide the fluidity and rigidity to the membrane.

Pictorial representation:

The structure of fats, phospholipids and sterols are well represented in Fig. 1(a), (b) and (c).

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.
