Q: Answer the following question given this paragraph: 35.3 | The Central Nervous System By the end of this section, you will be able to: Identify the spinal cord, cerebral lobes, and other brain areas on a diagram of the brain Describe the basic functions of the spinal cord, cerebral lobes, and other brain areas The central nervous system (CNS) is made up of the brain, a part of which is shown in Figure 35.19 and spinal cord and is covered with three layers of protective coverings called meninges (from the Greek word for membrane). The outermost layer is the dura mater (Latin for "hard mother"). As the Latin suggests, the primary function for this thick layer is to protect the brain and spinal cord. The dura mater also contains vein-like structures that carry blood from the brain back to the heart. The middle layer is the web-like arachnoid mater. The last layer is the pia mater (Latin for "soft mother"), which directly contacts and covers the brain and spinal cord like plastic wrap. The space between the arachnoid and pia maters is filled with cerebrospinal fluid (CSF). CSF is produced by a tissue called choroid plexus in fluid-filled compartments in the CNS called ventricles. The brain floats in CSF, which acts as a cushion and shock absorber and makes the brain neutrally buoyant. CSF also functions to circulate chemical substances throughout the brain and into the spinal cord. Q: The three layers of protective coverings of the spinal cord is called what? Choices: - dermis - tendons - muscles - meninges A:
A: meninges

Q: Answer the following question given this paragraph: Autoimmune diseases occur when the immune system fails to recognize the body's own molecules as "self," or belonging to the person. Instead, it attacks body cells as though they were dangerous pathogens. There are more than 80 known autoimmune diseases. Recall that regulatory T cells help regulate the immune system. When autoimmune disorders occur, these regulatory T cells fail in their function. This results in damage to various organs and tissues. The type of autoimmune disorder depends on the type of body tissue that is affected. Q: What type of disease occurs when the immune system fails to recognize the body's own molecules? Choices: - gastrointestinal - cardiac - congenital - autoimmune A:
A: autoimmune

Q: Answer the following question given this paragraph: Electric generators convert mechanical energy to electric energy. The generator consists of some number of wire loops wrapped around an iron core and placed in a strong magnetic field. The loops of wire and the iron core are called the armature . The armature is mounted so that it can rotate freely inside the magnetic field. Mechanical energy is used to spin the armature in the field so that the wire loops cut across the field and produce electric current. The of this current is calculated by . Q: Electric generators convert what type of energy to electric energy? Choices: - electromagnetic energy - thermodynamic energy - fluid energy - mechanical energy A:
A: mechanical energy
