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 stimulus.
Question
One of the constants in the experiment was that the chloropyll content was measured every 48 hours.
A True
B False
![Scientists use data tables to organize their experimental data. Often, the data are graphed
because a graph can make the data easier to interpret. Graphs quickly show a relationship
between two variables.
Scientists exposed two groups of seedlings to various amounts of light. One group was
exposed to low light conditions (LL) and the other group was exposed to moderate light
(ML) conditions. Scientists measured the amount of chlorophyll in the seedlings at regular
intervals during a 48-hour period. The amount of chlorophyll in the seedlings is expressed
in micrograms of chlorophyll per gram of seedling (ug/g). The data from both groups are
shown in the graph below.
