Answer: LABORATORY EXPERIMENTS
Explanation:
Exponential growth can be define as the increase in per capita growth of the population when the resources available are surplus. A limiting factor is the one which is capable of limiting the growth, abundance and distribution of population of species. Predator populations, habitat conditions and food resources all are examples of limiting factors which can limit the growth of population exponentially.
Laboratory experiments cannot be consider as limiting factor hence, are not responsible for limiting the exponential growth.
After sensing a drop in calcium levels in the body,parathyroid hormone from the parathyroid glands will be secreted in a negative feedback mechanism of homeostasis
first the parathyroid hormone stimulates release of calcium ions from the bone through the process of bone reorption
then the parathyroid hormone will reduce urinary excretion of calcium by increasing its re absorption in the nephron
finally , the parathyroid hormone will increase the rate of vitamin d synthesis in the small intestine to yield more calcium

brain. It constitutes the hippocampus, amygdala, limbic cortex and septal area.
