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 epigastric region is a portion of the <u>abdominal </u>cavity.
The correct option is d.
The greatest hollow area in the body is the abdominal cavity. Its lower limit is the upper plane of the pelvic cavity, and its upper barrier is the diaphragm, a sheet of muscle and connective tissue that divides it from the chest cavity. The spinal column, as well as the abdomen and other muscles, encircle it vertically.
The epigastrium is the top portion of your abdomen that is immediately below your rib cage. The epigastrium houses your pancreas and the duodenum, a section of your small intestine. Additionally, your stomach and liver are partially located here.

The expected result of this poison on secondary active transport is that the poison will prevents the conformational changes which are necessary for the pump to perform its function, thus preventing it from been able to carry out transportation of ions in and out of the cell.
