Answer the following question given this paragraph: Figure 7.3 In this illustration of the effects of crossing over, the blue chromosome came from the individual's father and the red chromosome came from the individual's mother. Crossover occurs between non-sister chromatids of homologous chromosomes. The result is an exchange of genetic material between homologous chromosomes. The chromosomes that have a mixture of maternal and paternal sequence are called recombinant and the chromosomes that are completely paternal or maternal are called non-recombinant. Q: The chromosomes that have a mixture of maternal and paternal sequence are called what? A:
OPTIONS:
- antibodies
- gene
- DNA
- recombinant
recombinant

Answer the following question given this paragraph: Q: What kind of tests may detect substances associated with particular disorders? A:
OPTIONS:
- hormonal
- electrical
- genetic
- biochemical

Answer: biochemical

Question: Answer the following question given this paragraph: Carbohydrates include sugars, starches, and fiber. Sugars and starches are used by the body for energy. One gram of sugar or starch provides 4 Calories of energy. Fiber doesn't provide energy, but it is needed for other uses. At age 13 years, you need about 130 grams of carbohydrates a day. Figure below shows good food sources of each type. Q: How many calories of energy does one gram of sugar or starch provide? A:
OPTIONS:
- 5
- 3
- 10
- 4
Answer: 4

input with options: Answer the following question given this paragraph: Diffraction is the bending of waves around a corner. Q: What is the bending of waves around a corner called? A:
OPTIONS:
- reflection
- propulsion
- absorption
- diffraction
output: diffraction

Q: Answer the following question given this paragraph: Unfortunately, maternal mt(DNA)is susceptible to mutations which are a cause of inherited disease, such as breast cancer. Although, it is important to note that most mutations do not lead to defected mtDNA. Heteroplasmy is the presence of a mixture of more than one type of mtDNA. Most people have homoplasmic cells, meaning that their cells contain only normal, undefected mtDNA. However, people with both normal, undefected mtDNA and not normal, defected mtDNA, may inherit mitochondrial diseases. The ultimate condition leading to disease is when the proportion of mutant mtDNA reaches a threshold, after which the cell can no longer cope, resulting in disease. This threshold varies among different tissues and different mutations. Q: What increases the chances of someone inheriting a mitochondrial disease? A:

OPTIONS:
- presence of defect transgenic and defect mtdna
- presence of defect transgenic and undefected mtdna
- presence of defect ornithopods and undefected mtdna
- presence of defect mtdna and undefected mtdna

A: presence of defect mtdna and undefected mtdna

Answer the following question given this paragraph: The spiral staircase in Figure below also contains an inclined plane. Do you see it? The stairs that wrap around the inside of the walls make up the inclined plane. The spiral staircase is an example of a screw. A screw is a simple machine that consists of an inclined plane wrapped around a cylinder or cone. No doubt you are familiar with screws like the wood screw in Figure below . The screw top of the container in the figure is another example. Screws move objects to a higher elevation (or greater depth) by increasing the force applied. Q: Screws move objects to a higher elevation by increasing what? A:
OPTIONS:
- velocity
- torque
- kinetic energy
- force applied
force applied
