Summary Introduction
To describe: The differences between a virus and a bacterium.
Introduction: A pathogen is a biological agent that causes disease or illness to its host. It is most commonly used for agents that disrupt the normal physiology of a multicellular animal or plant. The most prevalent infectious diseases are caused by bacterial and viral pathogens.
Expert Solution & Answer

Explanation of Solution
Bacteria and viruses are different from each other in several ways. The following table explains the differences between a virus and a bacterium:
Criteria | Virus | Bacterium |
Structure | A virus does not have a cell. It consists of | The bacterium is a cell. It has a cell membrane that is often enclosed by a cell wall. Some bacteria also have an additional protective layer called as capsule. |
Living conditions and reproduction | Viruses are obligate | Most bacteria can survive and reproduce outside a host if they have the required nutrients, temperature, pH, and so on. |
Susceptibility to drugs | Some viral infections can be managed with antiviral drugs that target definite stages of viral replication. | Most bacteria are susceptible to drugs called antibiotics. These drugs act can kill them or inhibit their growth. |

- 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.arrow_forwardYou 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?arrow_forwardYou 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.arrow_forward
- You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb? Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.arrow_forwardDesign a grafting experiment to determine if limb mesoderm determines forelimb / hindlimb identity. Include the experiment, a control, and an interpretation in your answer.arrow_forwardThe Snapdragon is a popular garden flower that comes in a variety of colours, including red, yellow, and orange.

- 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.
