Are the following bacteria motile?
S. Epidermis
P. Mirabilis
P. Putida
S. epidermis shows darting motility.
P. mirabilis is peritrichous (flagella all over the cell). So this is motile.
P. putida is lophotrichous (tuft of flagella at one end). So, it is motile.
Please rate high.
Are the following bacteria motile? S. Epidermis P. Mirabilis P. Putida
are the following bacteria aerobic, anaerobic or facilitative anaerobes? E. Coli S. Epidermidis P. Mirabilis P. Putida

A paramecium pushes against the water surrounding it with its motile cilia in order to propel itself forward. If the net force applied by the paramecium on the water is F~p, which of the following is true? A. The water pushes back with net force –F~p. B. The water pushes back with net force greater than F~p. C. The water pushes back with net force less than F~p. D. The water does not push back, since it is a liquid.
Which of the following is characteristic of cilia? They are whiplike, motile cellular extensions that occur in large numbers on the exposed surfaces of certain cells. They are used for cellular adhesion. They are substantially longer then flagella, and are less common than flagella in humans. They move substances in many directions across a cell's surfaces.

2. The growth rate of a population of bacteria is directly proportional to the population p() (measured in millions) at time t (measured in hours). (a) Model this situation using a differential equation. (b) Find the general solution to the differential equation (c) If the number of bacteria in the culture grew from p(0) = 200 to p(24) = 800 in 24 hours, what was the population after the first 12 hours?
