he purpose of this discussion to teach in practice, how you calculate the number of bacteria in a broth culture of a bacterium. Also, the knowing how a specific bacteria species grows in the laboratory conditions and determination of its growth curve allows studying effects of various chemical and physical factors on their growth. So, it is customary to find some basic growth characteristics of a bacterium for research. Q1. In your opinion, how can you use information gathered from growth curve measurements? Give some examples. Q2. Give an equation for measuring bacteria doubling time and show how you use it with an example. Q3. List various steps in making a bacterial growth curve. Q4. Do you think culturable bacteria isolated from an environment and in laboratory condition will have the same doubling time. Why/Why not? Explain.

What type of specimens where you able to see under each of the microscopes in the microscope activity

Sea levels are rising due to climate change while increasing numbers of people are moving into coastal areas. to accommodate more people, there has been increased construction of beachfront resorts and condominiums. how is this impacting sea turtle numbers and biodiversity and why? a. the increased human population in coastal areas has meant that more food is available to the turtles (e. g., dropped food, waste from restaurants), which has led to an increase in the numbers and diversity of sea turtles. b. there has been very little change in the numbers and biodiversity of sea turtles because the planet is so vast that they can simply relocate to less crowded beaches. c. this has resulted in a decrease in numbers and diversity of sea turtles because it is restricting available nesting sites, and hence reproduction. d. this has resulted in an increase in numbers and diversity of sea turtles because people are around to protect them from natural predators.

What environmental cues and landmarks do the geese use to determine the timing and direction of their migration over the mountains? how do they find their way?
