Q: Answer the following question given this paragraph: Mateusz Kulawik. Mosses and trees are all part of the plant kingdom . CC BY 2.0. Q: Which kingdom are mosses and trees included in? A:

OPTIONS:
- protista
- fungus
- gymnosperm
- plant

A: plant

input: OPTIONS:
- lungs
- dialysis
- arteries
- kidneys Now, answer this question: Answer the following question given this paragraph: The kidneys also need constant pressure to filter the blood. When the blood pressure drops too low, the kidneys increase the pressure. One way is by producing angiotensin, a blood vessel-constricting protein. This protein also signals the body to retain sodium and water. Together, the constriction of blood vessels and retention of sodium and water help restore normal blood pressure. Q: What organs need constant pressure to filter the blood? A:
A:
output: kidneys

Answer the following question given this paragraph: For a bacteria, many aspects of gene regulation are due to the presence or absence of certain nutrients. In prokaryotes, repressors bind to regions called operators that are generally located immediately downstream from the promoter. Activators bind to the upstream portion of the promoter. Q: In prokaryotes, what are the regions called that repressors bind to? A:

OPTIONS:
- elements
- enablers
- consumers
- operators

Answer: operators

Problem: OPTIONS:
- electrification
- evaporation
- oxidation
- ionization
Q: Answer the following question given this paragraph: The process in which an atom becomes an ion is called ionization. It may occur when atoms are exposed to high levels of radiation. The radiation may give their outer electrons enough energy to escape from the attraction of the positive nucleus. However, most ions form when atoms transfer electrons to or from other atoms or molecules. For example, sodium atoms may transfer electrons to chlorine atoms. This forms positive sodium ions (Na + ) and negative chloride ions (Cl - ). You can see an animation of this process at the URL below. Q: What is the process in which an atom becomes an ion known as? A:
Answer: ionization

Problem:OPTIONS:
- weight
- axis
- angles
- radius

Answer the following question given this paragraph: One important characteristic that determines the way in which elements behave is the total size of each atom. Free atoms are spherical in shape, so the relative sizes of the elements can be compared by looking at each atom's atomic radius , which is the distance from an atom's nucleus to the electrons in the outermost orbitals. You might expect atoms to generally grow larger as they go up in atomic number (which is equal to the total number of electrons in the neutral atom). Indeed, if you look at a single group of the periodic table, this trend holds true. Iodine is larger than bromine, which is in turn larger than chlorine and fluorine. In the case of a single group, each successive row places electrons in a higher principal energy level. Since higher energy levels are farther from the nucleus on average, this results in a larger total volume occupied by the atom. Q: Free atoms are spherical in shape, so the relative sizes of the elements can be compared by looking at each atom's atomic what? A:
****
A: radius

Problem:OPTIONS:
- life span
- cell structure
- immunology
- dna sequence

Answer the following question given this paragraph: Evidence from the fossil record can be combined with data from molecular clocks. A molecular clock uses DNA sequences (or the proteins they encode) to estimate relatedness among species. Molecular clocks estimate the time in geologic history when related species diverged from a common ancestor. Molecular clocks are based on the assumption that mutations accumulate through time at a steady average rate for a given region of DNA. Species that have accumulated greater differences in their DNA sequences are assumed to have diverged from their common ancestor in the more distant past. Molecular clocks based on different regions of DNA may be used together for more accuracy. Q: Species that have diverged from their common ancestors have greater differences in what? A:
****
A:
dna sequence
