Problem: OPTIONS:
- geographical distribution
- population phase
- proportional distribution
- population distribution
Q: Answer the following question given this paragraph: Population density is an average measure. Often, individuals in a population are not spread out evenly. Instead, they may live in clumps or some other pattern. How individuals in a population are distributed, or spread throughout their area, is called population distribution. You can see different patterns of population distribution in Figure below . Different patterns characterize different species and types of environments, as you can read in the figure. Q: Which measure shows how individuals in a population are distributed, or spread throughout their area? A:
Answer: population distribution
Problem: OPTIONS:
- arsenic
- carbon monoxide
- carbon dioxide
- radon
Q: Answer the following question given this paragraph: Radon is also radioactive and can easily be inhaled into the lungs. Over time, this internal radon exposure can lead to the development of lung cancer. The incidence of lung cancer in smokers exposed to radon is much higher than that in non-smokers exposed to radon since smoking has already produced some lung damage, and the radon simply makes the damage worse. Radon exposure is highest in homes lacking good air circulation to move the gas out of the residence. There are a number of inexpensive approaches to decreasing your exposure to radon. A good start is to test your living area for radon with a radon test kit. Q: Smoking increases the risk of cancer from what radioactive gas that can also be detected with a test kit for your home? A:
Answer: radon
Problem: OPTIONS:
- respiratory muscle
- abdominal muscle
- skeletal muscle
- cardiac muscle
Q: Answer the following question given this paragraph: Cardiac muscle is found only in the walls of the heart. When cardiac muscle contracts, the heart beats and pumps blood. Cardiac muscle contains a great many mitochondria, which produce ATP for energy. This helps the heart resist fatigue. Contractions of cardiac muscle are involuntary like those of smooth muscle. Q: What muscle is found only in the walls of the heart? A:
Answer:
cardiac muscle
