Answer the following question given this paragraph: Linnaeus classified organisms based on obvious physical traits. Basically, organisms were grouped together if they looked alike. After Darwin published his theory of evolution in the 1800s (discussed in the following chapter), scientists looked for a way to classify organisms that showed phylogeny. Phylogeny is the evolutionary history of a group of related organisms. It is represented by a phylogenetic tree , like the one in Figure below . Q: Which scientist was responsible for the theory of evolution by natural selection? A:
****
A: charles darwin

Answer the following question given this paragraph: Smooth muscle is organized in two ways: as single-unit smooth muscle, which is much more common; and as multiunit smooth muscle. The two types have different locations in the body and have different characteristics. Single-unit muscle has its muscle fibers joined by gap junctions so that the muscle contracts as a single unit. This type of smooth muscle is found in the walls of all visceral organs except the heart (which has cardiac muscle in its walls), and so it is commonly called visceral muscle. Because the muscle fibers are not constrained by the organization and stretchability limits of sarcomeres, visceral smooth muscle has a stress-relaxation response. This means that as the muscle of a hollow organ is stretched when it fills, the mechanical stress of the stretching will trigger contraction, but this is immediately followed by relaxation so that the organ does not empty its contents prematurely. This is important for hollow organs, such as the stomach or urinary bladder, which continuously expand as they fill. The smooth muscle around these organs also can maintain a muscle tone when the organ empties and shrinks, a feature that prevents "flabbiness" in the empty organ. In general, visceral smooth muscle produces slow, steady contractions that allow substances, such as food in the digestive tract, to move through the body. Multiunit smooth muscle cells rarely possess gap junctions, and thus are not electrically coupled. As a result, contraction does not spread from one cell to the next, but is instead confined to the cell that was originally stimulated. Stimuli for multiunit smooth muscles come from autonomic nerves or hormones but not from stretching. This type of tissue is found around large blood vessels, in the respiratory airways, and in the eyes. Q: What is another common term for single-unit smooth muscle? A:
OPTIONS:
- abnormal muscle
- lateral muscle
- energies muscle
- visceral muscle
visceral muscle

Answer the following question given this paragraph: Under the direction of osteocytes, osteoblasts continuously build up bone, while osteoclasts continuously break down bone. These processes help maintain mineral homeostasis. Q: What do osteoclasts do to bone? A:
OPTIONS:
- build it up
- strengthen it
- lengthen it
- break it down

Answer: break it down

Question: Answer the following question given this paragraph: An air mass is a large body of air that has about the same conditions throughout. For example, an air mass might have cold dry air. Another air mass might have warm moist air. The conditions in an air mass depend on where the air mass formed. Q: What is the term used for a large body of air of the same temperature and moisture conditions? A:
OPTIONS:
- air group
- sky mass
- air pool
- air mass
Answer: air mass

input with options: Answer the following question given this paragraph: 10.6 Exercise and Muscle Performance Hypertrophy is an increase in muscle mass due to the addition of structural proteins. The opposite of hypertrophy is atrophy, the loss of muscle mass due to the breakdown of structural proteins. Endurance exercise causes an increase in cellular. Q: Loss of muscle mass due to breakdown of structural proteins is known as what? A:
OPTIONS:
- distrophy
- mutation
- exhaustion
- atrophy
output: atrophy

Problem: OPTIONS:
- excitation
- relaxation
- exploitation
- emigration
Q: Answer the following question given this paragraph: Population growth is determined by rates of birth, death, immigration, and emigration. Q: Population growth is determined by rates of birth, death, immigration, and what else? A:
Answer:
emigration
