What is coral bleaching and what is responsible for this bleaching
Briefly describe and give at least one example each of the following coral reefs (a) Fringing reef
(b) Barrier reef.
Define dimorphism and explain what is responsible for this development.
Give 2 examples of an organism that exhibits dimorphism
1. Bacteria A and Bacteria B are considered hardy bacteria and can survive in extreme environments when grown individually. However, when they are grown together in a closed environment (on an agar plate), Bacteria A thrives, while Bacteria B eventually dies off.
Assume the population of Bacteria B completely dies off. Bacteria A are now transferred to an open environment where they have lots of room for growth and a continual supply of food. Over the course of three days, the population of bacteria steadily increases as follows:
Day 1: 1500 bacteria
Day 2: 3000 bacteria
Day 3: 7000 bacteria
Day 4: 13,000 bacteria
Is this population of bacteria r-selected or k-selected? Explain how you arrived at your answer. Hint: Review your definitions of “r” and “k.” (2 marks)
describe the sensory pathway that was activated when we submerged our hand in cold water (ice bucket) this question requires clear and discriptive explanation of physiological pathways
