Steroid estrogens, such as estrone, estradiol, and estriol, are dangerous to soil, plants, water resources, and humans.
<h3>What is "Assault on the Male"?</h3>

Answer:
The formed elements of the blood include red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes). Of these, leukocytes are primarily involved in the immune response. All formed elements originate in the bone marrow as stem cells (HSCs) that differentiate through hematopoiesis.
