Microbial Physiology

Microbial physiology is the branch of microbiology that is associated with studying the physiology of fungi, bacteria, and viruses. It is an important field of science concerning functional genomics and metabolic engineering.

Chemotaxis

The organism’s movement in a particular direction as a response to certain chemicals that are available in the environment is defined as chemotaxis. In brief, it can be defined as the occurrence of an organism’s movement in response to a certain chemical…

4. This question focuses on entrainment. a. What is entrainment? b. What environmental cues are involved in entrainment, and which one is most influential? c. Why is entrainment necessary? d. Assuming that a flash of darkness is an effective zeitgeber, what impact on circadian rhythms would you expect to result from an event such as the 2024 solar eclipse (assume it was viewed from Carbondale IL, where totality occurred at about 2 pm)? Explain your reasoning. You may wish to consult this phase response diagram. Phase Shift (Hours) Delay Zone Advance Zone Dawn Mid-day Dusk Night Dawn Time of Light Stimulus e. Finally, give a real-world example of how knowledge of circadian rhythms and entrainment has implications for human health and wellbeing or conservation biology. This example could be from your reading or from things discussed in class.
