Toxicologists study chemicals, drugs and other substances, and looks at how safe they're and their impact on living organisms. Toxicologists help in the development of methods that'll be used to know the harmful effects and the the dosages which causes it.
Furthermore, toxicology gives vital information and knowledge which the decision makers or regulatory agencies
in other biomedical fields can use in order to put programs in place that can be used to limit the exposures of humans to the substances.

During fertilization, the pituitary gland secretes the follicle-stimulating hormone, which acts on the follicles and stimulates them to produce progesterone. The correct option is B.
<h3>What is fertilization?</h3>
Fertilization is defined as the union of two haploid gametes, the spermatozoa and the oocyte, also known as the egg, to restore the diploid state, form a zygote through the process of egg activation, and initiate a series of mitotic divisions that result in cell differentiation and embryo development.
During fertilization, the pituitary gland secretes the follicle-stimulating hormone, which acts on the follicles and stimulates them to produce progesterone.
If fertilization occurs, the fertilized egg attaches to the uterine lining and a placenta develops.
The fertilized egg then sends a signal to the ovary to continue secreting progesterone, which keeps the pregnancy going by keeping the uterus lining thick and nourishing for the developing embryo.
Thus, the correct option is B.
