Q: Answer the following question given this paragraph: Heart: Coronary Artery Disease Coronary artery disease is the leading cause of death worldwide. It occurs when the buildup of plaquea fatty material including cholesterol, connective tissue, white blood cells, and some smooth muscle cellswithin the walls of the arteries obstructs the flow of blood and decreases the flexibility or compliance of the vessels. This condition is called atherosclerosis, a hardening of the arteries that involves the accumulation of plaque. As the coronary blood vessels become occluded, the flow of blood to the tissues will be restricted, a condition called ischemia that causes the cells to receive insufficient amounts of oxygen, called hypoxia. Figure 19.16 shows the blockage of coronary arteries highlighted by the injection of dye. Some individuals with coronary artery disease report pain radiating from the chest called angina pectoris, but others remain asymptomatic. If untreated, coronary artery disease can lead to MI or a heart attack. Q: What is the leading cause of death worldwide? A:

OPTIONS:
- lung disease
- cancer
- liver failure
- coronary artery disease

A: coronary artery disease

input: OPTIONS:
- underwater volcanoes
- tsunamis
- earthquakes
- new oceanic crust Now, answer this question: Answer the following question given this paragraph: In the oceans, plates move apart at mid-ocean ridges. Lava rises upward, erupts, and cools. Later, more lava erupts and pushes the original seafloor outward. This is seafloor spreading. Seafloor spreading forms new oceanic crust. The rising magma causes the ridge to be buoyant. This is why there is a mountain range running through the oceans. The plates pulling apart cause earthquakes. Q: What forms in the ocean from the seafloor spreading? A:
A:
output: new oceanic crust

Answer the following question given this paragraph: Commensalism is a symbiotic relationship in which one species benefits while the other species is not affected. An example is the relationship between birds called cattle egrets and cattle (see Figure below ). Cattle egrets feed on insects. They follow cattle herds around to take advantage of the insects stirred up by the feet of the cattle. The egrets get ready access to food from the relationship, whereas the cattle are not affected. Q: What is the term for a symbiotic relationship in which one species benefits while the other species is not affected? A:

OPTIONS:
- parasitism
- mutualism
- pollenation
- commensalism

Answer: commensalism

Problem: OPTIONS:
- parent trait
- major trait
- maladaptive trait
- polygenic trait
Q: Answer the following question given this paragraph: Natural selection for a polygenic trait changes the distribution of phenotypes. It may have a stabilizing, directional, or disruptive effect on the phenotype distribution. Q: Natural selection for what type of trait changes the distribution of phenotypes? A:
Answer: polygenic trait

Answer the following question given this paragraph: Molecular and Formula Masses The molecular mass of a substance is the sum of the average masses of the atoms in one molecule of a substance. It is calculated by adding together the atomic masses of the elements in the substance, each multiplied by its subscript (written or implied) in the molecular formula. Because the units of atomic mass are atomic mass units, the units of molecular mass are also atomic mass units. The procedure for calculating molecular masses is illustrated in Example 1. Q: What is calculated by adding together the atomic masses of the elements in the substance, each multiplied by its subscript (written or implied) in the molecular formula? A:

OPTIONS:
- mass effect
- fractional mass
- magnetic mass
- molecular mass

Answer:
molecular mass
