Answer the following question given this paragraph: Most cells are so small that you cannot see them without the help of a microscope . It was not until 1665 that English scientist Robert Hooke invented a basic light microscope and observed cells for the first time, by looking at a piece of cork. You may use light microscopes in the classroom. You can use a light microscope to see cells ( Figure below ). But many structures in the cell are too small to see with a light microscope. So, what do you do if you want to see the tiny structures inside of cells?. Q: What would you need to see most cells? A:
OPTIONS:
- ultraviolet
- infrared
- mirror
- microscope

Answer: microscope

Question: Answer the following question given this paragraph: Bacteria and viruses can infect the brain or spinal cord. An infection of the brain is called encephalitis. An infection of the membranes that cover the brain and spinal cord is called meningitis. A vaccine is available to prevent meningitis caused by viruses (see Figure below ). Q: An infection of the brain is called? A:
OPTIONS:
- tuberculosis
- influenza
- syphilis
- encephalitis
Answer: encephalitis

This intriguing story is another example of how small-scale physics can explain large-scale phenomena. Radioactive dating plays a role in determining the approximate age of the Earth. The oldest rocks on Earth solidified about 3.510 9 years agoa number determined by uranium-238 dating. These rocks could only have solidified once the surface of the Earth had cooled sufficiently. The temperature of the Earth at formation can be estimated based on gravitational potential energy of the assemblage of pieces being converted to thermal energy. Using heat transfer concepts discussed in Thermodynamics it is then possible to calculate how long it would take for the surface to cool to rock9 9 formation temperatures. The result is about 10 years. The first rocks formed have been solid for 3.510 years, so that 9 the age of the Earth is approximately 4.510 years. There is a large body of other types of evidence (both Earth-bound and solar system characteristics are used) that supports this age. The puzzle is that, given its age and initial temperature, the center of the Earth should be much cooler than it is today (see Figure 31.26). Q: What method plays a role in determining the approximate age of the earth and makes use of uranium? A:
OPTIONS:
- fuel dating
- carbon dating
- waste dating
- radioactive dating
output: radioactive dating

Q: Answer the following question given this paragraph: A genetic disorder that is caused by a mutation can be inherited. Therefore, people with a genetic disorder in their family may be concerned about having children with the disorder. Professionals known as genetic counselors can help them understand the risks of their children being affected. If they decide to have children, they may be advised to have prenatal ("before birth") testing to see if the fetus has any genetic abnormalities. One method of prenatal testing is amniocentesis. In this procedure, a few fetal cells are extracted from the fluid surrounding the fetus, and the fetal chromosomes are examined. Q: Professionals known as genetic counselors can help them understand the risks of? A:

OPTIONS:
- contagion
- infection
- disease
- children being affected

A: children being affected

input: OPTIONS:
- plasma membrane
- proton
- neutron
- electron Now, answer this question: Answer the following question given this paragraph: Q: The elements are arranged in rows, each representing the filling of what shell? A:
A:
output: electron

Question: Answer the following question given this paragraph: The Zygote Recall that at the point of fertilization, the oocyte has not yet completed meiosis; all secondary oocytes remain arrested in metaphase of meiosis II until fertilization. Only upon fertilization does the oocyte complete meiosis. The unneeded complement of genetic material that results is stored in a second polar body that is eventually ejected. At this moment, the oocyte has become an ovum, the female haploid gamete. The two haploid nuclei derived from the sperm and oocyte and contained within the egg are referred to as pronuclei. They decondense, expand, and replicate their DNA in preparation for mitosis. The pronuclei then migrate toward each other, their nuclear envelopes disintegrate, and the male- and femalederived genetic material intermingles. This step completes the process of fertilization and results in a single-celled diploid zygote with all the genetic instructions it needs to develop into a human. Most of the time, a woman releases a single egg during an ovulation cycle. However, in approximately 1 percent of ovulation cycles, two eggs are released and both are fertilized. Two zygotes form, implant, and develop, resulting in the. Q: During the typical human female ovulation cycles, how many eggs are released? A:
OPTIONS:
- four
- two
- three
- one
Answer:
one
