Answer the following question given this paragraph: Fructose, a sugar found in fruit, contains only carbon, oxygen, and hydrogen. It is used in ice cream to prevent a sandy texture. Complete combustion of 32.4 mg of fructose in oxygen produced 47.6 mg of CO2 and 19.4 mg of H2O. What is the empirical formula of fructose? 11. Coniine, the primary toxin in hemlock, contains only carbon, nitrogen, and hydrogen. When ingested, it causes paralysis and eventual death. Complete combustion of 28.7 mg of coniine produced 79.4 mg of CO2 and 34.4 mg of H2O. What is the empirical formula of the coniine? 12. Copper and tin alloys (bronzes) with a high arsenic content were presumably used by Bronze Age metallurgists because bronze produced from arsenic-rich ores had superior casting and working properties. The compositions of some representative bronzes of this type are as follows:. Q: How can you prevent your ice cream from getting a sandy texture? A:
OPTIONS:
- by using lowfat milk
- by adding oil
- by adding salt
- by using fructose

Answer: by using fructose

Question: Answer the following question given this paragraph: 26.4 Microscopes Although the eye is marvelous in its ability to see objects large and small, it obviously has limitations to the smallest details it can detect. Human desire to see beyond what is possible with the naked eye led to the use of optical instruments. In this section we will examine microscopes, instruments for enlarging the detail that we cannot see with the unaided eye. The microscope is a multiple-element system having more than a single lens or mirror. (See Figure 26.15) A microscope can be made from two convex lenses. The image formed by the first element becomes the object for the second element. The second element forms its own image, which is the object for the third element, and so on. Ray tracing helps to visualize the image formed. If the device is composed of thin lenses and mirrors that obey the thin lens equations, then it is not difficult to describe their behavior numerically. Q: A microscope can be made from two of what kind of lenses? A:
OPTIONS:
- inner
- angular
- outer
- convex
Answer: convex

input with options: Answer the following question given this paragraph: Forest and Kim Starr/Starr Environmental. Whisk ferns have yellow sporangia and no leaves . CC BY 3.0. Q: Which type of ferns have yellow sporangia and no leaves? A:
OPTIONS:
- Ostrich fern
- Hothouse fern
- Boston fern

Q: Answer the following question given this paragraph: Q: What type of reproduction usually occur during times of environmental stress? A:

OPTIONS:
- internal reproduction
- hysterical reproduction
- asexual reproduction
- sexual reproduction

A: sexual reproduction

input: OPTIONS:
- cell walls
- nucleic acids
- cytoplasm
- membrane proteins Now, answer this question: Answer the following question given this paragraph: Amoebozoa The amoebozoans characteristically exhibit pseudopodia that extend like tubes or flat lobes, rather than the hair-like pseudopodia of rhizarian amoeba (Figure 23.26). The Amoebozoa include several groups of unicellular amoeba-like organisms that are free-living or parasites. Q: The nuclear envelope is a double-layered plasma membrane like the cell membrane, although without what? A:
A:
output: membrane proteins

Question: Answer the following question given this paragraph: Animals such as bats and dolphins send out ultrasound waves and use their echoes, or reflected waves, to identify the locations of objects they cannot see. This is called echolocation. Animals use echolocation to find prey and avoid running into objects in the dark. You can see in the Figure below and also at the following URL how a bat uses echolocation to find insect prey. http://www. bsos. umd. edu/psyc/batlab/headaimmovies/nsf_challenge/nsf4. wmv. Q: What is the term for the method of sending out ultrasound waves to determine the locations of objects? A:
OPTIONS:
- catabolism
- magnetism
- morphology
- echolocation
Answer:
echolocation
