Q: Answer the following question given this paragraph: Learned behavior is any behavior that occurs only after experience or practice. The more intelligent a species is, the more it depends on learned behaviors, which have the advantage of being flexible. Ways in which animals learn behaviors include habituation, observational learning, conditioning, learning through play, and insight learning. Q: What is the term for any behavior that occurs only after experience or practice? A:

OPTIONS:
- practiced behavior
- saved behavior
- studied behavior
- learned behavior

A: learned behavior

input: OPTIONS:
- cell membrane
- cell wall
- placental barrier
- tight junction Now, answer this question: Answer the following question given this paragraph: A tight junction is a watertight seal between two adjacent animal cells (Figure 3.17b). Proteins hold the cells tightly against each other. This tight adhesion prevents materials from leaking between the cells. Tight junctions are typically found in the epithelial tissue that lines internal organs and cavities, and composes most of the skin. For example, the tight junctions of the epithelial cells lining the urinary bladder prevent urine from leaking into the extracellular space. Also found only in animal cells are desmosomes, which act like spot welds between adjacent epithelial cells (Figure 3.17c). They keep cells together in a sheet-like formation in organs and tissues that stretch, like the skin, heart, and muscles. Gap junctions in animal cells are like plasmodesmata in plant cells in that they are channels between adjacent cells that allow for the transport of ions, nutrients, and other substances that enable cells to communicate (Figure 3.17d). Structurally, however, gap junctions and plasmodesmata differ. Q: What is the term for a watertight seal between two adjacent animal cells? A:
A:
output: tight junction

Answer the following question given this paragraph: The amplitude , , is the distance from the equilibrium (or center) point of motion to either its lowest or highest point ( end points ). The amplitude, therefore, is half of the total distance covered by the oscillating object. The amplitude can vary in harmonic motion but is constant in SHM. The amplitude of a wave often determines its strength or intensity; the exact meaning of "strength" depends on the type of wave. For example, a sound wave with a large amplitude is a loud sound and a light wave with a large amplitude is very bright. Q: Often determining the strength or intensity of a wave, this term is the distance from the equilibrium point of motion to either its lowest or highest point? A:

OPTIONS:
- frequency
- density
- peak
- amplitude

Answer: amplitude

Problem: OPTIONS:
- digestive system
- musculoskeletal system
- circulatory system
- nervous system
Q: Answer the following question given this paragraph: Neurologist Neurologists are physicians who specialize in disorders of the nervous system. They diagnose and treat disorders such as epilepsy, stroke, dementia, nervous system injuries, Parkinson's disease, sleep disorders, and multiple sclerosis. Neurologists are medical doctors who have attended college, medical school, and completed three to four years of neurology residency. When examining a new patient, a neurologist takes a full medical history and performs a complete physical exam. The physical exam contains specific tasks that are used to determine what areas of the brain, spinal cord, or peripheral nervous system may be damaged. For example, to check whether the hypoglossal nerve is functioning correctly, the neurologist will ask the patient to move his or her tongue in different ways. If the patient does not have full control over tongue movements, then the hypoglossal nerve may be damaged or there may be a lesion in the brainstem where the cell bodies of these neurons reside (or there could be damage to the tongue muscle itself). Neurologists have other tools besides a physical exam they can use to diagnose particular problems in the nervous system. If the patient has had a seizure, for example, the neurologist can use electroencephalography (EEG), which involves taping electrodes to the scalp to record brain activity, to try to determine which brain regions are involved in the seizure. In suspected stroke patients, a neurologist can use a computerized tomography (CT) scan, which is a type of X-ray, to look for bleeding in the brain or a possible brain tumor. To treat patients with neurological problems, neurologists can prescribe medications or refer the patient to a neurosurgeon for surgery. Q: Neurologists are physicians who specialize in disorders of what system? A:
Answer: nervous system

Problem:OPTIONS:
- mean diffusion
- hard diffusion
- brain diffusion
- simple diffusion

Answer the following question given this paragraph: The oxygen enters the bloodstream from the alveoli , tiny sacs in the lungs where gas exchange takes place ( Figure below ). The transfer of oxygen into the blood is through simple diffusion. Q: How is oxygen transferred into the bloodstream? A:
****
A: simple diffusion

Problem:OPTIONS:
- few together
- further apart
- small together
- closer together

Answer the following question given this paragraph: Particles of a hypothetical ideal gas have no significant volume and do not attract or repel each other. In general, real gases approximate this behavior at relatively low pressures and high temperatures. However, at high pressures, the molecules of a gas are crowded closer together, and the amount of empty space between the molecules is reduced. At these higher pressures, the volume of the gas molecules themselves becomes appreciable relative to the total volume occupied by the gas (Figure 9.36). The gas therefore becomes less compressible at these high pressures, and although its volume continues to decrease with increasing pressure, this decrease is not proportional as predicted by Boyle's law. Q: At high pressures, how are the molecules of a gas crowded? A:
****
A:
closer together
