Answer the following question given this paragraph: A solution is a mixture of two or more substances, but it's not just any mixture. A solution is a homogeneous mixture. In a homogeneous mixture, the dissolved particles are spread evenly through the mixture. The particles of the solution are also too small to be seen or to settle out of the mixture. To put solutions in context as a type of mixture, watch the video at this URL: http://www. youtube. com/watch?v=z2vM-G5I92U . Q: A solution is what type of mixture, where the dissolved particles are spread evenly through the mixture? Choices: - saline - gaseous - heterogeneous - homogeneous A:
homogeneous

Answer the following question given this paragraph: Metabolism and Obesity Obesity in the United States is epidemic. The rate of obesity has been steadily rising since the 1980s. In the 1990s, most states reported that less than 10 percent of their populations was obese, and the state with the highest rate reported that only 15 percent of their population was considered obese. By 2010, the U. Centers for Disease Control and Prevention reported that nearly 36 percent of adults over 20 years old were obese and an additional 33 percent were overweight, leaving only about 30 percent of the population at a healthy weight. These studies find the highest levels of obesity are concentrated in the southern states. They also find the level of childhood obesity is rising. Obesity is defined by the body mass index (BMI), which is a measure of an individual's weight-to-height ratio. The normal, or healthy, BMI range is between 18 and 24.9 kg/m2. Overweight is defined as a BMI of 25 to 29.9 kg/m2, and obesity is considered to be a BMI greater than 30 kg/m2. Obesity can arise from a number of factors, including overeating, poor diet, sedentary lifestyle, limited sleep, genetic factors, and even diseases or drugs. Severe obesity (morbid obesity) or long-term obesity can result in serious medical conditions, including coronary heart disease; type 2 diabetes; endometrial, breast, or colon cancer; hypertension (high blood pressure); dyslipidemia (high cholesterol or elevated triglycerides); stroke; liver disease; gall bladder disease; sleep apnea or respiratory diseases; osteoarthritis; and infertility. Research has shown that losing weight can help reduce or reverse the complications associated with these conditions. Q: What is the measure of an individual's weight-to-height ratio called? Choices: - body density index (bdi) - body matter index (bmi) - density index (di) - body mass index (bmi) A:
(Answer)
body mass index (bmi)

Ques:Answer the following question given this paragraph: CHAPTER SUMMARY 21.1 Viral Evolution, Morphology, and Classification Viruses are tiny, acellular entities that can usually only be seen with an electron microscope. Their genomes contain either DNA or RNAnever bothand they replicate using the replication proteins of a host cell. Viruses are diverse, infecting archaea, bacteria, fungi, plants, and animals. Viruses consist of a nucleic acid core surrounded by a protein capsid with or without an outer lipid envelope. The capsid shape, presence of an envelope, and core composition dictate some elements of the classification of viruses. The most commonly used classification method, the Baltimore classification, categorizes viruses based on how they produce their mRNA. Q: Categorized based on how they produce their mrna using the baltimore classification method, what consist of a nucleic acid core surrounded by a protein capsid with or without an outer lipid envelope? Choices: - bacteria - amphibians - parasites - viruses A:

Ans:viruses
Ques: Answer the following question given this paragraph: In some cases, a population of one species disperses throughout an area, and each finds a distinct niche or isolated habitat. Over time, the varied demands of their new lifestyles lead to multiple speciation events originating from a single species, which is called adaptive radiation. From one point of origin, many adaptations evolve causing the species to radiate into several new ones. Island archipelagos like the Hawaiian Islands provide an ideal context for adaptive radiation events because water surrounds each island, which leads to geographical isolation for many organisms (Figure 11.16). The Hawaiian honeycreeper illustrates one example of adaptive radiation. From a single species, called the founder species, numerous species have evolved, including the eight shown in Figure 11.16. Q: In adaptive radiation, what is the name of the initial species that then subsequently becomes multiple other ones? Choices: - pioneer - father - Mother - founder A:
Ans:
founder
