Scientific studies suggest that some animals regulate their intake of different types of food available in the environment to achieve a balance between the proportion, and ultimately the total amount, of macronutrients, consumed. Macro-nutrients are categorized as protein, carbohydrate or fat/lipid. A seminal study on the macro-nutrient intake of migratory locust nymphs (Locusta migratoria) suggested that the locust nymphs studied sought and ate combinations of food that balanced the intake of protein to carbohydrate in a ratio of 45:55 [1]. Assume that a locust nymph finds itself in an environment where only two sources of food are available, identified as food X and food Y . Food X is 20% protein and 80% carbohydrate, whereas food Y is 70% protein and 30% carbohydrate. Assuming that the locust eats exactly 100 mg of food per day, determine how many milligrams of food X and food Y the locust needs to eat per day to reach the desired intake balance between protein and carbohydrate.

Some studies suggest that women have their first baby at age 35 or older are at increased risk of having a baby with low birth weight. A researcher chose a random sample of 125 women age 35 or older who were pregnant with their first child and followed them through the pregnancy. The mean weight of the 125 newborns was 3111.4 grams with a standard deviation of 501.3 grams. Is there evidence to suggest low birth weight for newborns who...

Mitochondria and chloroplasts are two types of organelles in eukaryotic cells. Current studies suggest that both organelles may have evolved by endosymbiosis of prokaryotes. Describe the functions of these two organelles and propose one structural evidence that strongly supports this endosymbiotic hypothesis.

Some environmentalists claim that the ways we raise and collect animals and fish for food are fundamentally unethical. They point to the suffering of animals within the factory farming industry, the pollution caused by untreated animal waste, the use of hormones and antibiotics, the decimation of fish populations, and the fact that current farming practices are ultimately unsustainable in terms of their environmental impact. Making the changes that these environmentalists claim are necessary, however, would likely be devastating to the...

In recent studies, some criminologists suggest that the "Broken Windows Theory" actually does not address the crime problem.
