Q: Answer the following question given this paragraph: Living species of chordates are classified into three major subphyla: Vertebrata, Urochordata, and Cephalochordata. Vertebrates are all chordates that have a backbone. The other two subphyla are invertebrate chordates that lack a backbone. Members of the subphylum Urochordata are tunicates (also called sea squirts). Members of the subphylum Cephalochordata are lancelets . Both tunicates and lancelets are small and primitive. They are probably similar to the earliest chordates that evolved more than 500 million years ago. Q: Vertebrates are all chordates that have a what? A:

OPTIONS:
- circulatory system
- fossil
- brain
- backbone

A: backbone

input: OPTIONS:
- monophobic
- hydrophonic
- soluble
- hydrophobic Now, answer this question: Answer the following question given this paragraph: The other end of each phospholipid molecule is nonpolar and has no electric charge. This end of the phospholipid molecule repels polar water and is described as hydrophobic, or "water hating. ". Q: What word describes a molecule that repels polar water? A:
A:
output: hydrophobic

Answer the following question given this paragraph: Q: In most animals, what sense is related to balance or equilibrium? A:

OPTIONS:
- vision
- tasting
- feeling
- hearing

Answer: hearing

Problem: OPTIONS:
- reflective and continental
- micro and continental
- amorphous and continental
- oceanic and continental
Q: Answer the following question given this paragraph: The crust is less than 1% of Earth by mass. The two types are oceanic crust and continental crust. Q: What are the two types of earth crust? A:
Answer: oceanic and continental

Problem:OPTIONS:
- arbitrary mutations
- sight mutations
- cancerous mutations
- nonsense mutations

Answer the following question given this paragraph: These mutations may result in a protein with the same function, with altered function, or with no function. Silent mutations , as they code for the same amino acid, will have no altered effect on the protein. Missense mutations may have a minor effect or a dramatic effect on the protein. Nonsense mutations usually have the most dramatic effet. Depending on the position of the premature stop codon, nonsense mutations may result in an unstable mRNA that cannot be translated, or in a truncated mRNA and a much "smaller" protein without any significant activity. Q: Which kind of mutations have the most dramatic effect on proteins? A:
****
A: nonsense mutations

Problem:OPTIONS:
- mixture
- organism
- cell
- element

Answer the following question given this paragraph: The smallest piece of an element that maintains the identity of that element is called an atom. Individual atoms are extremely small. It would take about fifty million atoms in a row to make a line that is 1 cm long. The period at the end of a printed sentence has several million atoms in it. Atoms are so small that it is difficult to believe that all matter is made from atomsbut it is. The concept that atoms play a fundamental role in chemistry is formalized by the modern atomic theory, first stated by John Dalton, an English scientist, in 1808. It consists of three parts: 1. Q: An atom is the smallest unit of what that maintains the identity of the latter? A:
****
A:
element
