Problem: Given the question: Nate and Andy were two zoologists. They have been studying the characteristics of nocturnal and diurnal animals. Andy studied nocturnal animals, while Nate studied diurnal animals. Which zoologist learned more about animals that are active during the night? Hint: Animals may avoid becoming prey by living out of sight of predators, whether in caves, burrows, or by being nocturnal. Nocturnality is an animal behavior characterized by activity during the night and sleeping during the day. This is a behavioral form of detection avoidance called crypsis used by animals to either avoid predation or to enhance prey hunting. Predation risk has long been recognized as critical in shaping behavioral decisions. For example, this predation risk is of prime importance in determining the time of evening emergence in echolocating bats. Although early access during brighter times permits easier foraging, it also leads to a higher predation risk from bat hawks and bat falcons. This results in an optimum evening emergence time that is a compromise between the conflicting demands.Another nocturnal adaptation can be seen in kangaroo rats. They forage in relatively open habitats, and reduce their activity outside their nest burrows in response to moonlight. During a full moon, they shift their activity towards areas of relatively dense cover to compensate for the extra brightness.

input question: Two sisters went to the doctor to get screened for cancer. Lisa had cancer, while her sister Beth didn't. Lisa was terrified, but her sister comforted her. Which sister had a disease caused by mutations? Hint: Cancer is a disease that causes cells to divide out of control. Normally, the body has systems that prevent cells from dividing out of control. But in the case of cancer, these systems fail. Cancer is usually caused by mutations. Mutations are random errors in genes. Mutations that lead to cancer usually happen to genes that control the cell cycle. Because of the mutations, abnormal cells divide uncontrollably. This often leads to the development of a tumor. A tumor is a mass of abnormal tissue. As a tumor grows, it may harm normal tissues around it. Anything that can cause cancer is called a carcinogen . Carcinogens may be pathogens, chemicals, or radiation.???
output answer: Lisa

Planet X had two large oceans. Ice ocean had few submarine volcanoes, while Tropical ocean had thousands of active volcanoes on the ocean floor. Which ocean had fewer volcanoes blasting steam high above its surface? Hint: Submarine volcanoes are common features of the ocean floor. In shallow water, active volcanoes disclose their presence by blasting steam and rocky debris high above the ocean's surface. In the ocean's deep, the tremendous weight of the water above prevents the explosive release of steam and gases; however, they can be detected by hydrophones and discoloration of water because of volcanic gases. Pillow lava is a common eruptive product of submarine volcanoes and is characterized by thick sequences of discontinuous pillow-shaped masses which form under water. Even large submarine eruptions may not disturb the ocean surface due to the rapid cooling effect and increased buoyancy of water (as compared to air) which often causes volcanic vents to form steep pillars on the ocean floor. Hydrothermal vents are common near these volcanoes, and some support peculiar ecosystems based on dissolved minerals. Over time, the formations created by submarine volcanoes may become so large that they break the ocean surface as new islands or floating pumice rafts.

Q: Keith was a studying for his chemistry exam. He got interested in solubility of different substances. For that, he conducted five tests, test A, test B, test C, test D, and test E. in test A, he used some liquid solute in a solvent in room temperature. Then in test B, he increased the temperature. In test C, he used some gaseous solute in a solvent in room temperature. But in test D, he increased the temperature. Finally, in test E he replaced the solvents in each of the earlier tests with water. In case C would the solute be less or more soluble than case D? Hint: As you can see in Figure above , solid and liquid solutes generally become more soluble as the temperature increases. This is true for solvents other than water as well. This effect varies quite a bit by substance. For example, the solubility of KNO 3 has a very strong temperature dependence (its solubility curve has a large slope), whereas the solubility of NaCl is minimally influenced by temperature (its solubility curve is nearly flat). For gaseous solutes, solubility decreases at higher temperatures. We will look more at this effect later in the lesson.

Question: Two neighboring towns had different demographics. Hill town had younger inhabitants, most of them in their 30's and 40's. Lake town was inhabited by elderly people, most of them above 65 years of age. Which town had more people that have retired from work? Hint: Old age begins in the mid-60s and lasts until the end of life. Most people over 65 have retired from work, freeing up their time for hobbies, grandchildren, and other interests. Stamina, strength, reflex time, and the senses all decline during old age, and the number of brain cells decreases as well. The immune system becomes less efficient, increasing the risk of serious illnesses such as cancer and pneumonia. Diseases such as Alzheimer's disease that cause loss of mental function also become more common.
Answer: Lake

Please answer this: Big continent used more air polluting substances, while Small continent was very protective towards the environment. Big continent got a hole in its ozone layer as a consequence of their actions. Which continent used more chlorine gasses? Hint: Unfortunately, the layer of good ozone is being destroyed by air pollution. The chief culprits are chlorine and bromine gases. They are released in aerosol sprays, coolants, and other products. Loss of ozone has created an ozone hole over Antarctica. Ozone depletion results in higher levels of UV radiation reaching Earth. In humans, this increases skin cancers and eye cataracts. It also disturbs the nitrogen cycle, kills plankton, and disrupts ocean food webs. The total loss of the ozone layer would be devastating to most life. It's rate of loss has slowed with restrictions on pollutants, but it is still at risk.
