Answer the following question given this paragraph: Tissues may be organized into organs. An organ is a structure composed of two or more types of tissue that work together to do a specific task. For example, the heart is an organ. It consists of muscle, nerve, and other types of tissues. Its task is to pump blood. Q: What is the heart's main task? A:
OPTIONS:
- make blood
- clean blood
- split blood cells
- pump blood

Answer: pump blood

Question: Answer the following question given this paragraph: Similar to chromosomal alteration mutations, deletion or insertion mutations add or remove genetic information. Small deletions or insertions in the DNA will alter the reading frame. Deletions remove one or more nucleotides from the DNA, whereas insertions add one or more nucleotides into the DNA. These mutations in the coding region of a gene may also alter the splicing of the mRNA, known as a splice site mutation . Mutations which alter the reading frame are known as frameshift mutations . Splice site mutations and frameshift mutations both can dramatically change the mRNA, altering the final protein product. Q: Deletions remove one or more what from the dna? A:
OPTIONS:
- codons
- exons
- genes
- nucleotides
Answer: nucleotides

input with options: Answer the following question given this paragraph: A cell membrane is essentially a mixture of phospholipids that form a phospholipid bilayer. One definition of a cell is a collection of molecules surrounded by a phospholipid bilayer that is capable of reproducing itself. The simplest cells are bacteria, which consist of only a single compartment surrounded by a single membrane. Animal and plant cells are much more complex, however, and contain many different kinds of compartments, each surrounded by a membrane and able to carry out specialized tasks. Q: What term is used to describe a collection of molecules surrounded by a phospholipid bilayer that is capable of reproducing itself? A:
OPTIONS:
- atom
- proteins
- organism
- cell
output: cell

Q: Answer the following question given this paragraph: Diversifying Selection Sometimes two or more distinct phenotypes can each have their advantages and be selected for by natural selection, while the intermediate phenotypes are, on average, less fit. Known as diversifying selection (Figure 19.8), this is seen in many populations of animals that have multiple male forms. Large, dominant alpha males obtain mates by brute force, while small males can sneak in for furtive copulations with the females in an alpha male's territory. In this case, both the alpha males and the "sneaking" males will be selected for, but medium-sized males, which can't overtake the alpha males and are too big to sneak copulations, are selected against. Diversifying selection can also occur when environmental changes favor individuals on either end of the phenotypic spectrum. Imagine a population of mice living at the beach where there is light-colored sand interspersed with patches of tall grass. In this scenario, light-colored mice that blend in with the sand would be favored, as well as dark-colored mice that can hide in the grass. Medium-colored mice, on the other hand, would not blend in with either the grass or the sand, and would thus be more likely to be eaten by predators. The result of this type of selection is increased genetic variance as the population becomes more diverse. Q: Sometimes two or more distinct phenotypes can each have their advantages and be selected for by natural selection; this is known as what? A:

OPTIONS:
- extra selection
- multiplying selection
- shedding selection
- diversifying selection

A: diversifying selection

Electromagnets are used to lift large masses of magnetic materials such as scrap iron, rolls of steel, and auto parts. Q: What are used to lift large masses of magnetic materials such as scrap iron, rolls of steel, and auto parts? A:
A:
output: electromagnets

Question: Answer the following question given this paragraph: Metalloids such as boron have an outer energy level that is about half full. These elements need to gain or lose too many electrons for a full outer energy level to come about easily. As a result, these elements are not very reactive. They may be able to conduct electricity but not very well. Q: About how full is the outer energy level in metalloids? A:
OPTIONS:
- nearly empty
- three-fourth full
- a quarter full
- half full
Answer:
half full
