Problem:OPTIONS:
- bacteria
- ribosomes
- chromatids
- dna

Answer the following question given this paragraph: Figure 10.4 Double-stranded DNA wraps around histone proteins to form nucleosomes that have the appearance of "beads on a string. " The nucleosomes are coiled into a 30-nm chromatin fiber. When a cell undergoes mitosis, the chromosomes condense even further. Q: Double strands of what wrap around histone proteins to form nucleosomes, which are coiled into a chromatin fiber? A:
****
A: dna

Answer the following question given this paragraph: Figure 11.35 (a) Capillary action depends on the radius of a tube. The smaller the tube, the greater the height reached. The height is negligible for large-radius tubes. (b) A denser fluid in the same tube rises to a smaller height, all other factors being the same. Q: What domain-level category of cells can contain more than 1000 times the dna found in a typical bacterial cell? A:
OPTIONS:
- chromosomes
- mutations
- genetic
- eukaryotic
eukaryotic

Answer the following question given this paragraph: A Geiger counter provides a sensitive means of detecting radioactivity. A tube is filled with an inert gas, which will conduct electricity when radiation enters it. When a charged particle comes into the tube, it changes the electrical potential between the anode and the cathode. This change in potential in the tube produces a change in voltage in the electrical circuit and registers as a count. Geiger counters are fairly inexpensive and reliable, so they are useful in a wide range of applications. More complicated types of counters are also available, but are generally used in sophisticated experiments. Q: What counter provides a sensitive means of detecting radioactivity? A:
OPTIONS:
- calorie
- bouncy
- gravity
- geiger

Answer: geiger

Question: Answer the following question given this paragraph: The last step in a scientific investigation is communicating what you have learned with others. This is a very important step because it allows others to test your hypothesis. If other researchers get the same results as yours, they add support to the hypothesis. However, if they get different results, they may disprove the hypothesis. When scientists share their results, they should describe their methods and point out any possible problems with the investigation. Results can be communicated in various ways. A scientist usually contributes material through publication in a peer-reviewed scientific journal. Peer-review ensures the material is of an acceptable quality for the scientific community. Scientists also write review articles, book chapters, and even whole books. They also regularly participate in scientific meetings, presenting their material in front of large audiences of their peers. Q: What is the last step in a scientific investigation? A:
OPTIONS:
- documenting findings
- verifying findings
- retesting findings
- communicating findings
Answer: communicating findings

input with options: Answer the following question given this paragraph: Figure 29.17 The tails of the Hale-Bopp comet point away from the Sun, evidence that light has momentum. Dust emanating from the body of the comet forms this tail. Particles of dust are pushed away from the Sun by light reflecting from them. The blue ionized gas tail is also produced by photons interacting with atoms in the comet material. (credit: Geoff Chester, U. Navy, via Wikimedia Commons). Q: The tails of the hale-bopp comet point away from the sun, evidence that light has what property of motion? A:
OPTIONS:
- inertia
- velocity
- acceleration
- momentum
output: momentum

Problem: OPTIONS:
- absorption
- regression
- filtration
- digestion
Q: Answer the following question given this paragraph: Digestion and Absorption Digestion is the mechanical and chemical break down of food into small organic fragments. It is important to break down macromolecules into smaller fragments that are of suitable size for absorption across the digestive epithelium. Large, complex molecules of proteins, polysaccharides, and lipids must be reduced to simpler particles such as simple sugar before they can be absorbed by the digestive epithelial cells. Different organs play specific roles in the digestive process. Q: What process is used to chemically and mechanically break down the food you eat into smaller parts? A:
Answer:
digestion
