Q: Answer the following question given this paragraph: Understanding Pigments Different kinds of pigments exist, and each absorbs only certain wavelengths (colors) of visible light. Pigments reflect the color of the wavelengths that they cannot absorb. All photosynthetic organisms contain a pigment called chlorophyll a, which humans see as the common green color associated with plants. Chlorophyll a absorbs wavelengths from either end of the visible spectrum (blue and red), but not from green. Because green is reflected, chlorophyll appears green. Other pigment types include chlorophyll b (which absorbs blue and red-orange light) and the carotenoids. Each type of pigment can be identified by the specific pattern of wavelengths it absorbs from visible light, which is its absorption spectrum. Many photosynthetic organisms have a mixture of pigments; between them, the organism can absorb energy from a wider range of visible-light wavelengths. Not all photosynthetic organisms have full access to sunlight. Some organisms grow underwater where light intensity decreases with depth, and certain wavelengths are absorbed by the water. Other organisms grow in competition for light. Plants on the rainforest floor must be able to absorb any bit of light that comes through, because the taller trees block most of the sunlight (Figure 5.11). Q: All photosynthetic organisms contain a pigment called what? A:
Answer: chlorophyll

Problem:OPTIONS:
- frictional forces
- tension forces
- hydrodynamic forces
- centripetal forces

Answer the following question given this paragraph: In the absence of a net force, objects move in a straight line. If they turn that is, if their velocity changes, even only in direction there must be an applied force. Forces which cause objects to turn around continuously in a circle are known as centripetal forces. When an object moves in a circle its velocity at any particular instant points in a direction tangent to the circle. The acceleration points towards the center of the circle, and so does the force acting on it. This is only natural, when you think about it if you feel a force pushing you towards your left as you walk forward, you will walk in a circle, always turning left. Q: Forces which cause objects to turn around continuously in a circle are known as? A:
****
A: centripetal forces

Answer the following question given this paragraph: The two tonsils are located on either side of the throat. They trap pathogens that enter the body through the mouth or nose. Q: Where are the two tonsils located? A:
OPTIONS:
- sinus
- nose
- tooth
- throat
throat

Answer the following question given this paragraph: Chemical reactions always involve energy. When methane burns, for example, it releases energy in the form of heat and light. Other chemical reactions absorb energy rather than release it. Q: Chemical reactions always involve energy. when methane burns, for example, it releases energy in the form of what? A:
OPTIONS:
- movement and light
- light and sound
- heat and movement
- heat and light

Answer: heat and light

Question: Answer the following question given this paragraph: The properties of cyclic hydrocarbons are generally quite similar to those of the corresponding open-chain compounds. So cycloalkanes (with the exception of cyclopropane, which has a highly strained ring) act very much like noncyclic alkanes. Cyclic structures containing five or six carbon atoms, such as cyclopentane and cyclohexane, are particularly stable. We will see in Chapter 16 "Carbohydrates" that some carbohydrates (sugars) form five- or six-membered rings in solution. Q: The properties of cyclic hydrocarbons are generally quite similar to those of the corresponding open-chain compounds. so cycloalkanes (with the exception of cyclopropane, which has a highly strained ring) act very much like noncyclic alkanes. cyclic structures containing five or six carbon atoms, such as cyclopentane and cyclohexane, are particularly what? A:
OPTIONS:
- large
- reactive
- small
- stable
Answer: stable

input: OPTIONS:
- heart attack
- infarction
- heartburn
- heart block Now, answer this question: Answer the following question given this paragraph: A heart block refers to an interruption in the normal conduction pathway. The nomenclature for these is very straightforward. SA nodal blocks occur within the SA node. AV nodal blocks occur within the AV node. Infra-Hisian blocks involve the bundle of His. Bundle branch blocks occur within either the left or right atrioventricular bundle branches. Q: What do we call an interruption in the normal conduction pathway of the heart? A:
A:
output:
heart block
