Question:
Sometimes traits can vary from parent to offspring. These changes are due to mutations. Mutations are a random change. Mutations are natural. Some mutations are harmful. In this case, the organism may not live to reproduce. The trait will not be passed onto offspring. Others variations in traits have no effect on survival. Can some mutations be good for a living thing? Other mutations can have great benefits. Imagine being the first moth that can blend into its background. It would have a better chance of survival. A living thing that survives is likely to have offspring. If it does, it may pass the new trait on to its offspring. Thats good news for the offspring. The offspring may be more likely to survive. Mutations are one way living things adapt to new conditions. After reading the above, is "Nothing can prevent it" the correct answer to the question "What might prevent a harmful mutation from being carried on into another generation?"?

Answer:
no

Question:
I am very hungry. I look for my mother. When is dinner? I ask. Dinner is at six, my mother says. What can we eat? I ask. We can pick food from our garden, she says. I help her pick corn, beans, and peas. The corn is yellow and white. The beans are small and brown. The peas are green and round. I put the beans in a basket. I put the peas in a bowl. Mother brings the corn. We go inside. I have dirty hands. I wash my hands with soap and water. The water is warm. My hands are now clean. Mother lets me stir the beans. I fill a pot with water. Mother puts the corn into the pot. She puts the pot on the stove. The water boils. Mary is my sister. Mary puts four plates on the table. Each plate is blue. We each eat two pieces of meat. I eat more corn than Mary. Mary eats more beans than our mother. What did you learn today? Mary asks. I can spell ten new words, I say. Mary can only spell two words. After reading the above, is "In a pot" the correct answer to the question "What do I put the beans and peas in?"?

Answer:
no

Question:
Tropical climates are found around the equator. These climates have warm temperatures year round. Tropical climates may be very wet or wet and dry. Tropical wet climates occur at or very near the equator. They have high rainfall year round. Tropical rainforests grow in this type of climate. Tropical wet and dry climates also occur near the equator. They receive less rainfall. Most of the rain falls in a single season. The rest of the year is dry. Few trees can withstand the long dry season. The main plants are grasses. Dry climates receive very little rainfall. They also have high rates of evaporation. This makes them even drier. Deserts can get less than 25 centimeters of rain per year. Thats less than 10 inches per year. How much rain do you get at your house? After reading the above, is "Forest trees" the correct answer to the question "What types of plants can survive the long dry season?"?

Answer:
no

Question:
Washington (CNN) -- The U.S. Food and Drug Administration announced Wednesday that laboratory tests on popular smoking devices known as electronic cigarettes have found they contain carcinogens and other toxic chemicals dangerous to humans. E-cigarettes are battery-operated and contain cartridges filled with nicotine and other chemicals. Known as "e-cigarettes," the devices are battery-operated and contain cartridges filled with nicotine and other chemicals, spiced with flavors such as chocolate, cola or bubble gum. While manufacturers tout e-cigarettes as a "healthy way" to smoke, federal health officials say the devices turn nicotine, which is highly addictive, and other chemicals into a vapor that is inhaled by the user. "The FDA is concerned about the safety of these products and how they are marketed to the public," said Dr. Margaret A. Hamburg, commissioner of the FDA. CNN contacted Florida-based Smoking Everywhere, one of the largest manufacturers of e-cigarettes, after the FDA announcement, and a spokeswoman said the company had no comment. Because e-cigarettes have not been submitted to the FDA for evaluation or approval, the agency had no way of knowing the levels of nicotine or the amounts or kinds of other chemicals that the various brands of these products deliver to the user. That is why the FDA began to test them. The FDA's Division of Pharmaceutical Analysis analyzed the ingredients in a small sample of cartridges from two leading brands of e-cigarettes. In releasing its information, the FDA did not identify the two companies, but said in one sample, diethylene glycol -- a chemical used in antifreeze that is toxic to humans -- was detected. Other samples detected carcinogens that are dangerous to those who smoke them, the FDA said. The FDA has been examining and seizing shipments of non-U.S.-made e-cigarettes at the U.S. border since summer 2008. To date, 50 shipments have been stopped. The products examined thus far meet the definition of a combination drug-device product under the Federal Food, Drug, and Cosmetic Act. "We know very little about these devices, said Dr. Jonathan Samet, director of the Institute for Global Health at the University of Southern California, "but to say they are healthy -- that's highly doubtful." After reading the above, is "Small sample of cartridges" the correct answer to the question "Where did the FDA find the chemical diethylene glycol?"?

Answer:
yes
