Answer:
Pancreas; islet of langerhans
Explanation:
Insulin and Glucagon are both hormones released into the bloodstream with the function of regulating blood sugar level. Insulin is released when the blood sugar level (glucose) is high, hence, it converts excess glucose to glycogen, which is stored in muscles. Insulin also helps the cell to utilize glucose as an energy source. Glucagon, on the other hand, functions to convert stored glycogen to glucose (glycogenolysis) when the glucose levels in the blood is low.
Both hormones i.e. Insulin and Glucagon are secreted into the bloodstream by an endocrine gland called PANCREAS, which is a digestive organ found near the stomach. Specifically, the pancreas contains regions that contain endocrine cells called ISLET CELLS. This region, called Islet of Langerhans, is where the hormones are produced in the PANCREAS.
Answer:
The atomic model is our understanding of how the atom is structured. At one point in history, people believed that any substance was simply made of that substance and would retain that property no matter how small a quantity it was reduced to. Later, some argued that all matter was made of tiny particles called atoms. While this is correct, later researchers found that even the atoms were made of smaller particles called electron, protons, and neutrons. More recently, scientists have discovered quarks, tiny particles that makeup protons and neutrons.
Isotopes of an element all have the same chemical behavior, but the unstable isotopes undergo spontaneous decay during which they emit radiation and achieve a stable state. This property of radioisotopes is useful in food preservation, archaeological dating of artifacts and medical diagnosis and treatment.
Answer:
ATP provides the energy needed for many essential processes in organisms and cells. These include intracellular signaling, DNA and RNA synthesis, Purinergic signaling, synaptic signaling, active transport, and muscle contraction.
