Question: Answer the following question given this paragraph: Chordates are defined by a set of four characteristics that are shared by these animals at some point during their development. In some chordates, all four traits are present in the adult animal and serve important functions. However, in many chordates, including humans, some traits are present only during the embryonic stage. After that, these traits may disappear. Q: Chordates are defined by a set of four characteristics that are shared by these animals at some point during their? A:
OPTIONS:
- death
- response
- birth
- development
Answer: development

input with options: Answer the following question given this paragraph: Saliva Saliva is essentially (95.5 percent) water. The remaining 4.5 percent is a complex mixture of ions, glycoproteins, enzymes, growth factors, and waste products. Perhaps the most important ingredient in salvia from the perspective of digestion is the enzyme salivary amylase, which initiates the breakdown of carbohydrates. Food does not spend enough time in the mouth to allow all the carbohydrates to break down, but salivary amylase continues acting until it is inactivated by stomach acids. Bicarbonate and phosphate ions function as chemical buffers, maintaining saliva at a pH between 6.35 and 6.85. Salivary mucus helps lubricate food, facilitating movement in the mouth, bolus formation, and swallowing. Saliva contains immunoglobulin A, which prevents microbes from penetrating the epithelium, and lysozyme, which makes saliva antimicrobial. Saliva also contains epidermal growth factor, which might have given rise to the adage "a mother's kiss can heal a wound. " Each of the major salivary glands secretes a unique formulation of saliva according to its cellular makeup. For example, the parotid glands secrete a watery solution that contains salivary amylase. The submandibular glands have cells similar to those of the parotid glands, as well as mucus-secreting cells. Therefore, saliva secreted by the submandibular glands also contains amylase but in a liquid thickened with mucus. The sublingual glands contain mostly mucous cells, and they secrete the thickest saliva with the least amount of salivary amylase. Q: Arguably the most important ingredient in saliva for digestion is a type of what, which initiates the breakdown of carbohydrates? A:
OPTIONS:
- amino
- genes
- fatty
- enzyme
output: enzyme

A: continents

input: OPTIONS:
- calculation
- density
- reflection
- precision Now, answer this question: Answer the following question given this paragraph: precision: A measure of how close a series of measurements are to one another. Precise measurements are highly reproducible, even if the measurements are not near the correct value. Q: A measure of how close a series of measurements are to one another is what? A:
A:
output: precision

Answer the following question given this paragraph: Scientists usually begin an investigation with facts. A fact is a bit of information that is true. Facts come from data collected from observations. Facts can also come from experiments that have been run. Data is factual information that results from an investigation. Facts and data are not subject to opinion or bias. An opinion is someone's subjective view or position on a subject. Q: In science, what is a bit of information that is true? A:

OPTIONS:
- lie
- theory
- falsehood
- a fact

Answer: a fact

Q: Answer the following question given this paragraph: All vertebrate organisms are in the phylum Chordata. Invertebrates, which make up about 95% (or more) of the animal kingdom, are divided into over 30 different phyla, some of which are listed below ( Table below ). Numerous invertebrate phyla have just a few species; some have only one described species, yet these are classified into separate phyla because of their unique characteristics. For example, sponges, with pores throughout their body, are from the phylum Porifera. Crabs and lobsters, with jointed appendages, are from the phylum Arthropoda. Q: Which phylum are all vertebrate organisms a member of? A:

OPTIONS:
- pylum protozoa
- phylum hominid
- phylum arthropod
- phylum chordata

A:
phylum chordata
