Problem:OPTIONS:
- hippocampus
- pituitary gland
- optic chiasm
- hypothalamus

Answer the following question given this paragraph: These two tracts connect the hypothalamus with the major parasympathetic nuclei in the brain stem and the preganglionic (central) neurons of the thoracolumbar spinal cord. The hypothalamus also receives input from other areas of the forebrain through the medial forebrain bundle. The olfactory cortex, the septal nuclei of the basal forebrain, and the amygdala project into the hypothalamus through the medial forebrain bundle. These forebrain structures inform the hypothalamus about the state of the nervous system and can influence the regulatory processes of homeostasis. A good example of this is found in the amygdala, which is found beneath the cerebral cortex of the temporal lobe and plays a role in our ability to remember and feel emotions. Q: What also receives input from other areas of the forebrain through the medial forebrain bundle? A:
****
A: hypothalamus

Answer the following question given this paragraph: The cardiovascular system moves nutrients and other substances throughout the body. Q: Which human body system system moves nutrients and other substances throughout the body? A:
OPTIONS:
- Digestive system
- Muscular system
- Integumentary system
- cardiovascular system
cardiovascular system

Answer the following question given this paragraph: In the troposphere, temperature decreases with altitude. The troposphere gets some of its heat directly from the Sun. Most, however, comes from Earth's surface. The surface is heated by the Sun. Some of that heat radiates back into the air. This makes the temperature higher near the surface than at higher altitudes. Q: What happens to temperature in the troposphere as the altitude increases? A:
OPTIONS:
- it increases
- it disappears
- it stays the same
- it decreases

Answer: it decreases

Question: Answer the following question given this paragraph: Learn some applications of radioactivity. Radioactive isotopes have a variety of applications. Generally, however, they are useful because either we can detect their radioactivity or we can use the energy they release. Radioactive isotopes are effective tracers because their radioactivity is easy to detect. A tracer is a substance that can be used to follow the pathway of that substance through some structure. For instance, leaks in underground water pipes can be discovered by running some tritium-containing water through the pipes and then using a Geiger counter to locate any radioactive tritium subsequently present in the ground around the pipes. (Recall that tritium is a radioactive isotope of hydrogen. ) Tracers can also be used to follow the steps of a complex chemical reaction. After incorporating radioactive atoms into reactant molecules, scientists can track where the atoms go by following their radioactivity. One excellent example of this is the use of carbon-14 to determine the steps involved in. Q: What is the name for a substance that can be used to follow the pathway of that substance through some structure? A:
OPTIONS:
- gel
- tracker
- solution
- tracer
Answer: tracer
