Answer the following question given this paragraph: An alkyl group is a group of atoms that results when one hydrogen atom is removed from an alkane. The group is named by replacing the -ane suffix of the parent hydrocarbon with -yl. For example, the CH3 group derived from methane (CH4) results from subtracting one hydrogen atom and is called a methyl group. The alkyl groups we will use most frequently are listed in Table 12.4 "Common Alkyl Groups". Alkyl groups are not independent molecules; they are parts of molecules that we consider as a unit to name compounds systematically. Table 12.4 Common Alkyl Groups. Q: A group of atoms that results when one hydrogen atom is removed from an alkane is referred to as what? A:

OPTIONS:
- chloride group
- hyrdrogen group
- nitrate group
- alkyl group

Answer: alkyl group

Problem: OPTIONS:
- heart
- liver
- brain
- lung
Q: Answer the following question given this paragraph: Emphysema is a chronic lung disease caused by the breakdown of the lung tissue. Symptoms of emphysema include shortness of breath, especially during exercise, and chronic cough, usually due to cigarette smoking, and wheezing, especially during expiration. Damage to the alveoli ( Figure below ), is not curable. Smoking is the leading cause of emphysema. Q: Emphysema is a chronic disease caused by the breakdown of the what tissue? A:
Answer: lung

Problem:OPTIONS:
- hemoglobin
- sugar
- glucose
- insulin

Answer the following question given this paragraph: Type 1 diabetes occurs when the immune system attacks normal cells of the pancreas. Since the cells in the pancreas are damaged, the pancreas cannot make insulin. Type 1 diabetes usually develops in childhood or adolescence. Q: Type 1 diabetes results in the pancreas not being able to make what ? A:
****
A: insulin

Answer the following question given this paragraph: Solstice refers to the position of the Sun when it is closest to one of the poles. At equinox, the Sun is directly over the Equator. Q: When is the sun directly over the equator? A:
OPTIONS:
- Winter
- Midsummer
- Fall
- equinox
equinox

Answer the following question given this paragraph: Physiological Processes of Echinoderms Echinoderms have a unique system for gas exchange, nutrient circulation, and locomotion called the water vascular system. The system consists of a central ring canal and radial canals extending along each arm. Water circulates through these structures allowing for gas, nutrient, and waste exchange. A structure on top of the body, called the madreporite, regulates the amount of water in the water vascular system. "Tube feet," which protrude through openings in the endoskeleton, may be expanded or contracted using the hydrostatic pressure in the system. The system allows for slow movement, but a great deal of power, as witnessed when the tube feet latch on to opposite halves of a bivalve mollusk, like a clam, and slowly, but surely pull the shells apart, exposing the flesh within. Q: Echinoderms have a unique system for gas exchange, nutrient circulation, and locomotion called the water vascular system. the system consists of a central ring canal and radial canals extending along each arm. water circulates through these structures allowing for gas, nutrient, and this? A:
OPTIONS:
- water evaporation
- nerve exchange
- cell exchange
- waste exchange

Answer: waste exchange

input with options: Answer the following question given this paragraph: A photon isn't a fixed amount of energy. Instead, the amount of energy in a photon depends on the frequency of the electromagnetic wave. The frequency of a wave is the number of waves that pass a fixed point in a given amount of time, such as the number of waves per second. In waves with higher frequencies, photons have more energy. Q: The number of waves that pass a fixed point in a given amount of time is called what? A:
OPTIONS:
- wavelength of a wave
- spectroscopy of a wave
- spread of a wave
- frequency of a wave
output:
frequency of a wave
