Problem: OPTIONS:
- electron count
- atomic mass
- real number
- atomic number
Q: Answer the following question given this paragraph: The type of atom is determined by the atomic number (i. e. the number of protons). The atomic mass of an atom is approximately the number of protons plus the number of neutrons. Typically, the atomic mass listed in a periodic table is an average, weighted by the natural abundances of different isotopes. Q: Adding the number of protons plus the number of neutrons in an atom, decides it's approximate mass, what is another word for this value? A:
Answer: atomic number

Problem:OPTIONS:
- chloroplasts
- microbial
- carbonate
- chlorophyll

Answer the following question given this paragraph: Bacteria called cyanobacteria are very important. They are bluish green in color (see Figure below ) because they contain chlorophyll. They make food through photosynthesis and release oxygen into the air. These bacteria were probably responsible for adding oxygen to the air on early Earth. This changed the planet's atmosphere. It also changed the direction of evolution. Ancient cyanobacteria also may have evolved into the chloroplasts of plant cells. Q: Cyanobacteria are bluish green in color because they contain what? A:
****
A: chlorophyll

Answer the following question given this paragraph: Q: What kind of symmetry do echinoderm larvae have? A:
OPTIONS:
- internal
- radial
- spherical
- bilateral
bilateral

Answer the following question given this paragraph: Alloys can be one of two general types. In one type, called a substitutional alloy, the various atoms simply replace each other in the crystal structure. In another type, called an interstitial alloy, the smaller atoms such as carbon fit in between the larger atoms in the crystal packing arrangement. Q: Historically, malaria has rivaled what as the leading cause of human death by infectious disease? A:
OPTIONS:
- heart attack
- hepatitis
- cancer
- tuberculosis

Answer: tuberculosis

Question: Answer the following question given this paragraph: make up the middle layer and the bulk of the heart wall. The outer layer of cells is called the epicardium, of which the second layer is a membranous layered structure called the pericardium that surrounds and protects the heart; it allows enough room for vigorous pumping but also keeps the heart in place to reduce friction between the heart and other structures. The heart has its own blood vessels that supply the heart muscle with blood. The coronary arteries branch from the aorta and surround the outer surface of the heart like a crown. They diverge into capillaries where the heart muscle is supplied with oxygen before converging again into the coronary veins to take the deoxygenated blood back to the right atrium where the blood will be re-oxygenated through the pulmonary circuit. The heart muscle will die without a steady supply of blood. Atherosclerosis is the blockage of an artery by the buildup of fatty plaques. Because of the size (narrow) of the coronary arteries and their function in serving the heart itself, atherosclerosis can be deadly in these arteries. The slowdown of blood flow and subsequent oxygen deprivation that results from atherosclerosis causes severe pain, known as angina, and complete blockage of the arteries will cause myocardial infarction: the death of cardiac muscle tissue, commonly known as a heart attack. Q: What is the term for the blockage of an artery by the buildup of fatty plaques? A:
OPTIONS:
- fibrosis
- cancers
- clumps
- atherosclerosis
Answer: atherosclerosis

input: OPTIONS:
- parasite
- Thumb
- Milk production
- backbone Now, answer this question: Answer the following question given this paragraph: Chordates include vertebrates and invertebrates that have a notochord. Chordates also have a post-anal tail, dorsal hollow nerve cord, and pharyngeal slits. Vertebrate chordates have a backbone, while invertebrate chordates do not. Invertebrate chordates include tunicates and lancelets; both are primitive marine organisms. Q: What do vertebrate chordates possess that invertebrate chordates do not? A:
A:
output:
backbone
