Mike and John are brothers. Their dad sent them to the doctor's office to get tested for hepatitis because Mike was feeling sick all the time. It turned out Mike has hepatitis B, while John doesn't. Which brother didn't have a disease which can be passed through sexual activity? Hint: Hepatitis B is a disease of the liver. It is caused by a virus called hepatitis B, which can be passed through sexual activity. Hepatitis B causes vomiting. It also causes yellowing of the skin and eyes. The disease goes away on its own in some people. Other people are sick for the rest of their lives. In these people, the virus usually damages the liver. It may also lead to liver cancer. Medicines can help prevent liver damage in these people. There is also a vaccine to protect against hepatitis B.

Q: Two friends studied permaculture together. Bill studied about mycorrhiza, while Red studied about hugel kultur. Which friend learned less about fungus colonizing the roots of a host plant by growing around the root cells? Hint: A mycorrhiza (Greek for "fungus roots") is a symbiotic association between a fungus and the roots of a plant. In a mycorrhizal association, the fungus may colonize the roots of a host plant by either growing directly into the root cells, or by growing around the root cells. This association provides the fungus with relatively constant and direct access to glucose, which the plant produces by photosynthesis. The mycelia of the fungi increase the surface area of the plant's root system. The larger surface area improves water and mineral nutrient absorption from the soil.
A: Red

Question: John and Keith are two friends. They went to see an ophthalmologist for an eye cheek up. The doctor found that John had myopia, but Keith had normal eyes. He advised them according to his findings. Whose eyeball would be longer than normal, John or Keith? Hint: Nearsightedness, or myopia, is the condition in which nearby objects are seen clearly, but distant objects appear blurry. The Figure below shows how it occurs. The eyeball is longer (from front to back) than normal. This causes images to be focused in front of the retina instead of on the retina. Myopia can be corrected with concave lenses. The lenses focus images farther back in the eye, so they fall on the retina instead of in front of it.
Answer: John

[Q]: Beach town was hit hard by the hurricane. Hill town was spared, being situated 50 miles south. the eye of the hurricane passed almost through Beach town. Which town had more rain falling? Hint: So much rain falling so fast causes some of the damage from a hurricane. But a lot of the damage is caused by storm surge. Storm surge is very high water located in the low pressure eye of the hurricane. The very low pressure of the eye allows the water level to rise above normal sea level. Storm surge can cause flooding when it reaches land ( Figure below ). High winds do a great deal of damage in hurricanes. High winds can also create very big waves. If the large waves are atop a storm surge, the high water can flood the shore. If the storm happens to occur at high tide, the water will rise even higher.

[A]: Beach

input: Please answer the following: David is an entomologist. He recently got interested in ants and their behaviors. To that end, he studied a group of ants, which be labeled as case A. To compare ants with other ant like creatures he studied another hymenopteran group, which he labeled as case B. Moreover, he noticed two distinct trails made by the ants, trail A or trail B. Trail A was followed by many ants, but trail B was abandoned by them. Which trail would more likely be longer, trail A or trail B? Hint: Ants communicate with each other using pheromones, sounds, and touch. The use of pheromones as chemical signals is more developed in ants, such as the red harvester ant, than in other hymenopteran groups. Like other insects, ants perceive smells with their long, thin, and mobile antennae. The paired antennae provide information about the direction and intensity of scents. Since most ants live on the ground, they use the soil surface to leave pheromone trails that may be followed by other ants. In species that forage in groups, a forager that finds food marks a trail on the way back to the colony; this trail is followed by other ants, these ants then reinforce the trail when they head back with food to the colony. When the food source is exhausted, no new trails are marked by returning ants and the scent slowly dissipates. This behaviour helps ants deal with changes in their environment. For instance, when an established path to a food source is blocked by an obstacle, the foragers leave the path to explore new routes. If an ant is successful, it leaves a new trail marking the shortest route on its return. Successful trails are followed by more ants, reinforcing better routes and gradually identifying the best path.Ants use pheromones for more than just making trails. A crushed ant emits an alarm pheromone that sends nearby ants into an attack frenzy and attracts more ants from farther away. Several ant species even use "propaganda pheromones" to confuse enemy ants and make them fight among themselves. Pheromones are produced by a wide range of structures including Dufour's glands, poison glands and glands on the hindgut, pygidium, rectum, sternum, and hind tibia. Pheromones also are exchanged, mixed with food, and passed by trophallaxis, transferring information within the colony. This allows other ants to detect what task group (e.g., foraging or nest maintenance) other colony members belong to. In ant species with queen castes, when the dominant queen stops producing a specific pheromone, workers begin to...

The hospital in Y city had a good disposal site in which they disposed of Biomedical wastes, but the hospital in the neighboring city X had big problems, because the biomedical waste contaminated the ground water and affected the population. Which city had less child mortality? Hint: One of the most adverse impacts of poor waste management, especially municipal waste, is the incidence and prevalence of diseases such as malaria and respiratory problems, as well as other illnesses through the contamination of ground water. Biomedical wastes pose great danger in Bangladesh too as a report estimated that 20% of the biomedical waste is "highly infectious" and is a hazard since it is often disposed of into the sewage system or drains.[6] Such poor sanitation has serious consequences for the health of the residents and a report suggests that "most of the child mortality could be related with this problem".[7] With regards to the living standards, solid waste leads to blockage in the drainage system which leads to flooding in the streets. Consequently, mosquitoes and bad odour are among the negative impacts resulted.[7]
