Answer:
The pathogen is Pasteurella multicida.
Explanation:
Pastuerella multicida is a gram negative, non motile bacteria that is penicillin sensitive and belongs to the family pasteurellaceae. It is a common cause infection from dogs and cats bites.
Gram staining is a method use to distinguish and classify bacterial species into large groups which are either gram positive or gram negative.
Gram negative bacteria are bacteria that do not retain the crystal violet stain used in their gram staining while
Gram positive bacteria are bacteria that retain the crystal violet stain by their thick peptidoglycan cell wall found in them.
Substrate Concentration I believe
Answer:
That is administered and controlled
Step-by-step explanation:
A variable is the condition or a product that may vary without the influence of any investigator. Such variables can be found abundantly in our daily lives, ranging from air to sunlight. Controlling such variables ensures the limitation of their influence on the outcome of an experiment. In connection to this experiment, the variables that are controlled are the mineral content in the water, the amount of bacteria food, the amount of light and the the constant temperature of 20 degrees C.
If not administered or these variables controlled, the experiment would not clearly explain the impact of caffeine on the heart beat of the water fleas as other variables may have influenced it. Thus variables are controlled to study the singular impact of any agent or effect.
