In the above experiment, the number of bacterial colonies after three days is a dependent variable. Option A is the right answer.
The variables in the experiment that are reliant on the cause independent variables are referred to as dependent variables.
For instance, consider the amount of bacterial colonies after three days.
The variables in the experiment that can be modified or manipulated are known as independent variables.
For example, temperature, nutrient content, and so forth.
As a result, in the provided experiment, the number of bacterial colonies after three days is a dependent variable.
Answer:
PEP carboxykinase and pyruvate kinase
Explanation:
as the body needs more amount of glucose as the time passes, so PEP carboxykinase level will increase to convert the fats and proteins in to the glucose to fulfill the body needs. the function of PEP carboxykinase is to convert the fat and proteins to glucose during gluconeogenesis process when there is requirement of body in low diet conditions.
Pyruvate kinase level will increase as the phosphorylation of PK will cause the inhibition and recycling of enzyme called phosphoenolpyruvate. this will results in the increase synthesis of glucose.
The correct answer is option B.
This shows commensalistic relationship.
What is commensalism?
Commensalism is a biological relationship (symbiosis) in which individuals of one species profit, while those of the other species suffer neither advantages nor disadvantages.
This is in contrast to parasitism, which is related to parasitism in that the parasitoid has a free-living state and eventually kills its host rather than just damaging it, amensalism, where one is damaged while the other is unaffected, and parasitism, where one is harmed and the other benefits.
The host species, which is largely unharmed, may provide nourishment, shelter, support, or means of mobility for the commensal.
