B) Vacuoles allow water to enter and exit the paramecium.
Answer:
In a research there are two variables independent and dependent variable. independent variable is defined as the variable which is controlled and changed in a scientific experiment and evaluate the effects on the dependent variable while the variable which are tested and measured in experiment are called dependent variable.
When antibiotic is sprayed at one side of the petri dish, the bacterial growth on that side will eventually decrease in comparison to other side.
So, the independent variable in this experiment will be antibiotic because it is used to understand the growth of bacteria by decreasing their numbers and the dependent variable in this experiment will be bacteria as they vary according to the change in independent variable that is antibiotic.
The appropriate response is the Olfactory Bulb. It is a mind structure in charge of our feeling of smell. Situated at the tip of the olfactory projection, the knob forms data about smells in the wake of getting tangible contribution from the nose.
The olfactory bulb is a heap of afferent nerve strands from the mitral and tufted cells of the olfactory globule that interfaces with a few target areas in the mind, including the piriform cortex, amygdala, and entorhinal cortex.
