Summary Introduction
Concept introduction:
Biofilms are the colonies formed by different species of bacteria. These colonies are initiated by one bacterium that attaches to the surface of vulnerable body parts, likea tooth or lung tissue. The other microbes subsequently attach to either the first bacterium or the inevitable sugar and protein secretions by it.
Biofilms are present in almost every natural environment, and it is an adaptation strategy of bacteria for the sustenance of their lives. The different species of bacteria cooperate and interact with each other while forming biofilms, and functioning in these colonies.
Biofilms are also involved inthe passing of genetic material from one microbe to its neighboring microbe. Therefore, they can cause infections and also develops resistance to antimicrobials.

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.
