Please answer this: I read this background article the other day: Centripetal force is, simply, the force that causes centripetal acceleration. Objects that move in uniform circular motion all have an acceleration toward the center of the circle and therefore, they must also suffer a force toward the center of the circle. That force is the centripetal force. For orbiting satellites, such as the moon orbiting the earth or the earth orbiting the sun, the centripetal force is produced by gravity. When an Olympic hammer thrower whirls a massive ball on a chain, the centripetal force is created by the athlete and transmitted by the chain. I am facing a new situation today: Adam wants to show his little brother a trick. He gets a bucket of water and says to him "I bet i can turn this bucket upside down and no water will fall out". His brother doesn't believe him of course. So Adam takes the bucket by the handle and quickly starts spinning it in a circle. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Will the centripetal force on the bucket increase or decrease as Adam spins it faster?

Answer: increase
Problem: I read this background article the other day: A plant's first line of defense against abiotic stress is in its roots. If the soil holding the plant is healthy and biologically diverse, the plant will have a higher chance of surviving stressful conditions.The plant responses to stress are dependent on the tissue or organ affected by the stress. For example, transcriptional responses to stress are tissue or cell specific in roots and are quite different depending on the stress involved.One of the primary responses to abiotic stress such as high salinity is the disruption of the Na+/K+ ratio in the cytoplasm of the plant cell. High concentrations of Na+, for example, can decrease the capacity for the plant to take up water and also alter enzyme and transporter functions. Evolved adaptations to efficiently restore cellular ion homeostasis has led to a wide variety of stress tolerant plants.Facilitation, or the positive interactions between different species of plants, is an intricate web of association in a natural environment. It is how plants work together. In areas of high stress, the level of facilitation is especially high as well. This could possibly be because the plants need a stronger network to survive in a harsher environment, so their interactions between species, such as cross-pollination or mutualistic actions, become more common to cope with the severity of their habitat.Plants also adapt very differently from one another, even from a plant living in the same area. When a group of different plant species was prompted by a variety of different stress signals, such as drought or cold, each plant responded uniquely. Hardly any of the responses were similar, even though the plants had become accustomed to exactly the same home environment.Rice (Oryza sativa) is a classic example. Rice is a staple food throughout the world, especially in China and India. Rice plants experience different types of abiotic stresses, like drought and high salinity. These stress conditions have a negative impact on rice production. Genetic diversity has been studied... I am facing a new situation today: Danny owned two parcels of land. parcel A had a soil with high salinity levels, while parcel B had a rich and healthy soil. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which parcel had plants with lower chances of surviving stressful conditions?

A: parcel A
Problem: Given the question: I read this background article the other day: Carbon dioxide is the most significant long-lived greenhouse gas in Earth's atmosphere. Since the Industrial Revolution anthropogenic emissions primarily from use of fossil fuels and deforestation have rapidly increased its concentration in the atmosphere, leading to global warming. Carbon dioxide also causes ocean acidification because it dissolves in water to form carbonic acid. I am facing a new situation today: China used alternative fuels to generate electricity, while Mongolia burned lots of fossil fuels. There were frequent debates between the two countries on this matter. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which country caused more deforestation?
++++++++++++++++++++++++++++++++
The answer is:
Mongolia
input question: I read this background article the other day: Protozoa generally feed by engulfing and digesting other organisms. As consumers, they have various roles in food chains and webs. Some are predators. They prey upon other single-celled organisms, such as bacteria. In fact, protozoa predators keep many bacterial populations in check. Other protozoa are herbivores. They graze on algae. Still others are decomposers. They consume dead organic matter. There are also parasitic protozoa that live in or on living hosts. For example, the protozoan that causes malaria lives inside a human host. For their part, protozoa are important food sources for many larger organisms, including insects and worms. I am facing a new situation today: Two groups of students learned about protozoa for a school project. Group P studied more about predatory protozoa, while group G studied about grazing and parasitic protozoa, plus portozoa as food sources. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which group learned less about protozoa that cause malaria????
output answer: Group P
I read this background article the other day: Any unused energy in food, whether it comes from carbohydrates, proteins, or lipids, is stored in the body as fat. An extra 3,500 Calories of energy results in the storage of almost half a kilogram (1 pound) of stored body fat. People who consistently consume more food energy then they need may become obese. Obesity occurs when the body mass index is 30.0 kg/m 2 or greater. Body mass index (BMI) is an estimate of the fat content of the body. It is calculated by dividing a person's weight (in kilograms) by the square of the person's height (in meters). Obesity increases the risk of health problems such as type 2 diabetes and hypertension. I am facing a new situation today: Two neighboring villages were living mostly off the land. Boar village was full of fat people, because they would overeat lots of animal products. Leap village was inhabited by vegetarians and vegans.Their food consumption was moderate. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which village had fewer people with increased risk of type 2 diabetes?
----
Answer: Leap
Q: I read this background article the other day: A few insects, such as mayflies and some moths, never eat. That's because their lives are over in just a few hours or days. Once these insects become adults, they lay eggs, and then die. On the other hand, some insects are very healthy eaters. A silkworm eats enough leaves to increase its weight more than 4,000 times in just 56 days, as the silkworm increases in size about 10,000 times since birth. A locust eats its own weight in plants every day. Just imagine eating your own weight in food every day. You probably couldn't. You would most likely get very sick even if you tried. I am facing a new situation today: Two entomologists liked studying all types of insects and arthropods. Bill was focused on insects that never eat. His buddy Paul was more focused on the feeding habits of other insects that eat a lot of food. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which friend studied fewer silkworms?
A:
Bill
