input: Please answer the following: Local hospital has launched a program to check if a patient has Retinitis. Resident ophthalmologist David is in charge of this program. In the first day of the program he checked two patients, patient A and patient B. The test result showed that patient A had Retinitis, but patient B did not have Retinitis. Then next day David checked two other patients, patient C and patient D. Patient C was 40 years old, but patient D was 80 years old. He found both patient C and D had Retinitis. Which patient would have inflammation of retina, patient A or patient B? Hint: Retinitis is inflammation of the retina in the eye, which can permanently damage the retina and lead to blindness. The retina is the part of your eye that is also known as the "sensing tissue." Retinitis may be caused by a number of different infectious agents. Retinitis, also called Retinitis pigmentosa, has a prevalence of one in every 2,500-7,000 people. This condition is one of the leading causes that leads to blindness in patients in the age range of 2060 years old.

Please answer this: There are 2 groups of prairie dogs that have been released into the wild. Group A was domesticated and therefor never learned to communicate danger to each other. Group B was rescued from a bad storm but lived in the wild for years before they were captured then released. One day the two groups encountered a lion that was trying to eat them. One of the members of group B made a peculiar high pitched sound, alerting the rest of it's members that there was something dangerous nearby and they all went inside their burrow and hid. The member of group A saw the lion and simply ran as fast as it could without altering any of the other members. Unfortunately one of group A's members was caught and eaten. Given there is a third group, Group C which was also domesticated, will Group C's chance for survival in the wild increase or decrease? Hint: Communication is any way that animals share information. Many animals live in social groups. For these animals, being able to communicate is essential. Communicating increases the ability of group members to cooperate and avoid conflict. Communication may help animals work together to find food and defend themselves from predators. It also helps them find mates and care for their offspring. In addition, communication helps adult animals teach the next generation learned behaviors. Therefore, communication generally improves the chances of animals surviving and reproducing.

Answer: decrease

Problem: Germany took steps to increase the use of renewable natural resources. Today, they are the leader in using renewable resources. Most of their energy requirements are met with renewable natural resources. But it's not the case with nearby Russia. Russia has been heavily depended on non-renewable natural resources. With the discovery of huge gas and oil reserves there is no sign that situation would change in Russia any time soon. Which country's natural resources would most likely last longer, Germany or Russia? Hint: Natural resources include energy, minerals and other materials. Natural resources may be renewable or non-renewable. Non-renewable resources cannot be replaced. When they're gone, they're gone. Renewable resources can be replaced. They can supply human activities forever. Fossil fuels are crucial for modern human society. Fossil fuels are essential for transportation, industry and agriculture. Renewable energy resources tend to be clean. They emit fewer pollutants and greenhouse gases than fossil fuels. Renewable resources often have other problems. They are more costly and less efficient than fossil fuels. Still, they have many advantages. Research is going into developing renewable resources. Conservation is the best way to increase resource availability. Anyone can conserve! You and your family can. Society can. The world can. Just reduce, reuse, recycle.

Problem: Given the question: Joy had a field full of flowering plants , that he used for medicinal and honey making purposes. Her friend Jill also had a piece of land where she cultivated plants that fertilize over wind spread pollen. Which friend had a field with a lower efficiency of fertilization? Hint: Scientists think that the earliest flowers attracted insects and other animals, which spread pollen from flower to flower. This greatly increased the efficiency of fertilization over wind-spread pollen, which might or might not actually land on another flower. To take better advantage of this "animal labor," plants evolved traits such as brightly colored petals to attract pollinators. In exchange for pollination, flowers gave the pollinators nectar.

input question: Two farmers had different pests attacking their plants. John had a big aphid problem, so he used all the methods available to get rid of them. Mike had a slug problem, but had almost no aphides. Which farmer didn't learn that aphids are resistant to pyrethroids? Hint: Insecticide control of aphids is difficult, as they breed rapidly, so even small areas missed may enable the population to recover promptly. Aphids may occupy the undersides of leaves where spray misses them, while systemic insecticides do not move satisfactorily into flower petals. Finally, some aphid species are resistant to common insecticide classes including carbamates, organophosphates, and pyrethroids.For small backyard infestations, spraying plants thoroughly with a strong water jet every few days may be sufficient protection. An insecticidal soap solution can be an effective household remedy to control aphids, but it only kills aphids on contact and has no residual effect. Soap spray may damage plants, especially at higher concentrations or at temperatures above 32 C (90 F); some plant species are sensitive to soap sprays.???

input question: Mary had two twin daughters, Mimi and Coco. Coco was healthy, but Mimi had hemophilia. Mimi took frequent trips to the doctor's office. Which girl had the normal ability to control blood clotting? Hint: Hemophilia is the name of a group of hereditary diseases that affect the body's ability to control blood clotting. Hemophilia is caused by a lack of clotting factors in the blood. Clotting factors are normally released by platelets. Since people with hemophilia cannot produce clots, any cut can put a person at risk of bleeding to death. The risk of internal bleeding is also increased in hemophilia, especially into muscles and joints. This disease affected the royal families of Europe.???

Coco
