Answer the following question given this paragraph: The pancreas is a large gland located near the stomach. Hormones secreted by the pancreas include insulin. Insulin helps cells absorb glucose from the blood. It also stimulates the liver to take up and store excess glucose. Q: Which hormone is secreted by the pancreas in a human body? Choices: - growth hormone - progesterone - estrogen - insulin A:

Answer the following question given this paragraph: In other materials, electrons fill the orbitals of the atoms that make up the material in a way to allow for each atom to have a tiny magnetic field, giving each atom a tiny north and south pole. There are large areas where the north and south poles of atoms are all lined up in the same direction. These areas are called magnetic domains . Generally, the magnetic domains point in different directions, so the material is still not magnetic. However, the material can be magnetized by placing it in a magnetic field. When this happens, all the magnetic domains become aligned, and the material becomes a magnet. This is illustrated in Figure below . Materials that can be magnetized are called ferromagnetic materials . They include iron, cobalt, and nickel. Q: Materials that can be magnetized are called? Choices: - atoms materials - iron materials - inclusions materials - ferromagnetic materials A:
ferromagnetic materials
