Q: Answer the following question given this paragraph: The idea of elements is not new. It dates back about 2500 years to ancient Greece. The ancient Greek philosopher Aristotle thought that all matter consists of just four elements. He identified the elements as earth, air, water, and fire.

Answer the following question given this paragraph: Structures like the human tail bone are called vestigial structures . Evolution has reduced their size because the structures are no longer used. The human appendix is another example of a vestigial structure. It is a tiny remnant of a once-larger organ. In a distant ancestor, it was needed to digest food. It serves no purpose in humans today. Why do you think structures that are no longer used shrink in size? Why might a full-sized, unused structure reduce an organism's fitness?. Q: What purpose does the appendix serve in humans today? A:
****
A: none

OPTIONS:
- tides
- ranges
- particles
- waves
waves

Answer the following question given this paragraph: Channel proteins provide an open channel or passageway through the cell membrane for molecules to move across. Many channel proteins allow the diffusion of ions. Ions are charged atoms. The charge makes it difficult to cross the cell membrane without assistance. Channel proteins are specific for the molecule they transport. For example a sodium ion crosses the membrane through a channel protein specific for sodium ions. Q: Ions are charged what? A:
OPTIONS:
- molecules
- protons
- isotopes
- atoms

Answer: atoms

input with options: Answer the following question given this paragraph: Gastrointestinal and Urinary Adjustments In adults, the gastrointestinal tract harbors bacterial floratrillions of bacteria that aid in digestion, produce vitamins, and protect from the invasion or replication of pathogens. In stark contrast, the fetal intestine is sterile. The first consumption of breast milk or formula floods the neonatal gastrointestinal tract with beneficial bacteria that begin to establish the bacterial flora. The fetal kidneys filter blood and produce urine, but the neonatal kidneys are still immature and inefficient at concentrating urine. Therefore, newborns produce very dilute urine, making it particularly important for infants to obtain sufficient fluids from breast milk or formula. Q: The first consumption of breast milk or formula floods the baby's gastrointestinal tract with what? A:
OPTIONS:
- hemoglobin
- nerves
- enzymes
- beneficial bacteria
output:
beneficial bacteria
