3, Below is the movement track made by a bacterium in a culture dish exposed to a heat lamp shining from the side. What kind of response has the bacterium made?
4. Differentiate (don't just define):
a. Territory and home range -
b. Map sense and compass sense -
5. In my paper on roost site selection by silver-haired bats that you summarized, what were the benefits that bats might get from choosing especially tall snags as roost trees?
3. Examining the track left by the bacterium there is first an attraction to the light then a repulsion. These are phototactic (light-sensitive) movements. It is unclear at what point the light was shone on the plate. If the start point is truly where the bacterum was when the light was turned on it demonstrates an attractive and repulsive behavior.
4. a. Home range is the scope of land that is occupied and returned to by an individual or mating pair. Territory is defined as the land occupied and defended by an individual ...
This solution of over 300 words discusses the type of movement of a bacterium make sin a culture dish under heated conditions, differentiates between territory and home range as well as map sense and compass sense. It also provides a reason on the roosting behavior of silver-haired bats, supported with referenced material.
