Chapter 33.5, Problem 1CC
Summary Introduction
To describe: The mechanism of attachment of sea star tube feet to the substrate.
Concept introduction:
Sea star is a marine animal that belongs to the Phylum Echinodermata. Sea star is commonly known as star fish due to its resemblance to star. Echinoderms are marine animals with the radially symmetrical body. They are deuterostomes (organisms in which blastopore forms anus).
The body of sea star and other echinoderms possess a central disc with projected arms (usually five in number). All echinoderms possess a water vascular system that helps them in locomotion, respiration and food acquisition. Tube feet are components of water vascular system that helps in locomotion. Each tube foot comprises a podium and an ampulla.

If using animals in medical experiments could save human lives, is it ethical to do so? In your answer, apply at least one ethical theory in support of your position.
You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?
You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.

- 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.arrow_forwardA sample of blood was taken from the above individual and prepared for haemoglobin analysis.
