Biologists as well as chemists and biochemists can be forensic scientists. Forensic scientists provide scientific evidence for use in courts, and their job involves examining trace material associated with crimes. Interest in forensic science has increased in the last few years, possibly because of popular television shows that feature forensic scientists on the job. Also, the development of molecular techniques and the establishment of DNA databases have updated the types of work that forensic scientists can do. Their job activities are primarily related to crimes against people such as murder, rape, and assault. Their work involves analyzing samples such as hair, blood, and other body fluids and also processing DNA (Figure 1.13) found in many different environments and materials. Forensic scientists also analyze other biological evidence left at crime scenes, such as insect parts or pollen grains. Students who want to pursue careers in forensic science will most likely be required to take chemistry and biology courses as well as some intensive math courses. Q: What type of science is the application of science to answer questions related to the law? A:
A:
output: forensic

Answer the following question given this paragraph: Atoms of different elements differ in size, mass, and other properties. Q: Different elements differ in the size, mass, and other properties of what fundamental structures? A:

OPTIONS:
- ions
- compounds
- particles
- atoms

Answer: atoms

Problem: OPTIONS:
- Recondition Mechanism
- load mechanism
- Adaptive Mechanism
- feedback mechanism
Q: Answer the following question given this paragraph: Hormones control many cell activities, so they are very important for homeostasis. But what controls the hormones themselves? Most hormones are regulated by feedback mechanisms. A feedback mechanism is a loop in which a product feeds back to control its own production. Most hormone feedback mechanisms involve negative feedback loops. Negative feedback keeps the concentration of a hormone within a narrow range. Q: What is the term for a loop in which a product feeds back to control its own production? A:
Answer: feedback mechanism

Problem:OPTIONS:
- water melts
- water freezes
- water evaporates
- water expands

Answer the following question given this paragraph: Ice wedging happens because water expands as it goes from liquid to solid. When the temperature is warm, water works its way into cracks in rock. When the temperature cools below freezing, the water turns to ice and expands. The ice takes up more space. Over time, this wedges the rock apart. Ice wedging is very effective at weathering. You can find large piles of broken rock at the base of a slope. These rocks were broken up by ice wedging. Once loose, they tumbled down the slope. Q: Why does ice wedging occur? A:
****
A: water expands

Answer the following question given this paragraph: For a hypothesis to be testable means that it is possible to make observations that agree or disagree with it. If a hypothesis cannot be tested by making observations, it is not scientific. Consider this statement:. Q: A hypothesis is scientific only if it can be tested by what? A:
OPTIONS:
- independent variable
- making a conclusion
- carbon dating
- making observations
making observations

Answer the following question given this paragraph: The age of a rock in years is its absolute age. The main evidence for absolute age comes from radiometric dating methods, such as carbon-14 dating. These methods depend on radioactive decay. Q: Radiometric dating methods, such as carbon-14 dating depend on what type of decay? A:
OPTIONS:
- microwave
- carbon
- nuclear
- radioactive

Answer:
radioactive
