Q: Answer the following question given this paragraph: The Pharynx The pharynx (throat) is involved in both digestion and respiration. It receives food and air from the mouth, and air from the nasal cavities. When food enters the pharynx, involuntary muscle contractions close off the air passageways. A short tube of skeletal muscle lined with a mucous membrane, the pharynx runs from the posterior oral and nasal cavities to the opening of the esophagus and larynx. It has three subdivisions. The most superior, the nasopharynx, is involved only in breathing and speech. The other two subdivisions, the oropharynx and the laryngopharynx, are used for both breathing and digestion. The oropharynx begins inferior to the nasopharynx and is continuous below with the laryngopharynx (Figure 23.12). The inferior border of the laryngopharynx connects to the esophagus, whereas the anterior portion connects to the larynx, allowing air to flow into the bronchial tree. Q: Digestion and respiration are both facilitated by the pharynx, more commonly called the what? A:

OPTIONS:
- esophagus
- sinus
- nose
- throat

A: throat

input: OPTIONS:
- carbohydrates
- Over done
- temperatures
- saturated Now, answer this question: Answer the following question given this paragraph: If a solution contains so much solute that its solubility limit is reached, the solution is said to be saturated, and its concentration is known from information contained inTable 9.2 "Solubilities of Various Solutes in Water at 25C (Except as Noted)". If a solution contains less solute than the solubility limit, it is unsaturated. Under special circumstances, more solute can be dissolved even after the normal solubility limit is reached; such solutions are called supersaturated and are not stable. If the solute is solid, excess solute can easily recrystallize. If the solute is a gas, it can bubble out of solution uncontrollably, like what happens when you shake a soda can and then immediately open it. Q: If a solution contains so much solute that its solubility limit is reached, the solution is said to be what? A:
A:
output: saturated

Answer the following question given this paragraph: and Z, the atomic number, is the number of protons. The protons and neutrons that make up the nucleus of an atom are callednucleons, and an atom with a particular number of protons and neutrons is called anuclide. Nuclides with the same number of protons but different numbers of neutrons are called isotopes. Isotopes can also be represented by an alternative notation that uses the name of the element followed by the mass number, such as carbon-12. The stable isotopes of oxygen, for example, can be represented in any of the following ways:. Q: What are protons and neutrons that make up the nucleus of an atom called? A:

OPTIONS:
- baryons
- pions
- electron shells
- nucleons

Answer: nucleons

Problem: OPTIONS:
- oil
- lava
- air
- water
Q: Answer the following question given this paragraph: Water cycling is extremely important to ecosystem dynamics. Water has a major influence on climate and, thus, on the environments of ecosystems, some located on distant parts of the Earth. Most of the water on Earth is stored for long periods in the oceans, underground, and as ice. Figure 46.13 illustrates the average time that an individual water molecule may spend in the Earth's major water reservoirs. Residence time is a measure of the average time an individual water molecule stays in a particular reservoir. A large amount of the Earth's water is locked in place in these reservoirs as ice, beneath the ground, and in the ocean, and, thus, is unavailable for short-term cycling (only surface water can evaporate). Q: What important liquid is stored throughout the earth in the oceans, underground, and in ice? A:
Answer: water

Problem:OPTIONS:
- protection from pests
- improves taste
- Faster growth
- promotes productivity

- energy
- absorption

Answer the following question given this paragraph: As food is pushed through the GI tract by peristalsis, it undergoes digestion. Digestion is the process of breaking down food into nutrients. There are two types of digestion: mechanical digestion and chemical digestion. Q: The process of breaking down food into nutrients is known as __________ A:
****
A:
digestion
