Q: I read this background article the other day: An apex predator, also known as an alpha predator or top predator, is a predator at the top of a food chain, with no natural predators.Apex predators are usually defined in terms of trophic dynamics, meaning that they occupy the highest trophic levels. Food chains are often far shorter on land, usually limited to being secondary consumers for example, wolves prey mostly upon large herbivores (primary consumers), which eat plants (primary producers). The apex predator concept is applied in wildlife management, conservation and ecotourism. I am facing a new situation today: Two cousins were fascinated about food chains in nature. Liam started reading about apex predators, while Fox read about grazers and large herbivores. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which cousin learned less about wolves?
A: Fox
Question: I read this background article the other day: In exercises such as weight lifting, skeletal muscle contracts against a resisting force (see Figure below ). Using skeletal muscle in this way increases its size and strength. In exercises such as running, the cardiac muscle contracts faster and the heart pumps more blood. Using cardiac muscle in this way increases its strength and efficiency. Continued exercise is necessary to maintain bigger, stronger muscles. If you don't use a muscle, it will get smaller and weakerso use it or lose it. I am facing a new situation today: Bill and Bob were two brothers. they were both into physical exercise, but Bill chose weight lifting, and Bob running. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which brother had smaller muscles?
Answer: Bob
[Q]: I read this background article the other day: In practice, the diameter of the aperture is chosen based on the focal length of the lens, the diameter and quality of the input beam, and its wavelength (longer wavelengths require larger apertures). If the hole is too small, the beam quality is greatly improved but the power is greatly reduced. If the hole is too large, the beam quality may not be improved as much as desired. The size of aperture that can be used also depends on the size and quality of the optics. To use a very small pinhole, one must use a focusing lens with a low f-number, and ideally the lens should not add significant aberrations to the beam. The design of such a lens becomes increasingly more difficult as the f-number decreases. I am facing a new situation today: David needs to purchase a camera for his photography class. He went to the local consumer electronics store to find himself a good camera. Two cameras caught his eye, camera A and camera B. Camera A had a very small pinhole, but camera B had larger aperture. David needs to decide which camera should he buy. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which camera would have higher beam quality?
****
[A]: camera A
input: Please answer the following: I read this background article the other day: Acceleration is a measure of the change in velocity of a moving object. It measures the rate at which velocity changes. Velocity, in turn, is a measure of the speed and direction of motion, so a change in velocity may reflect a change in speed, a change in direction, or both. Both velocity and acceleration are vectors. A vector is any measurement that has both size and direction. People commonly think of acceleration as in increase in speed, but a decrease in speed is also acceleration. In this case, acceleration is negative and called deceleration. A change in direction without a change in speed is acceleration as well. I am facing a new situation today: Jacob is an avid street car racer who is driving in his sleek black Mustang. He comes to a red light and sees the car next to him is an expensive looking Honda Civic, owned by a man named Alejandro. Jacob and Alejandro agree to race, and when the light turns green they both slam their feet on the gas pedal and take off. Jacob's car arrives at the light pole down the street from the light sooner than Alejandro's car, and he wins the race. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which person's car, Jacob's or Alejandro's, must have accelerated slower?
++++++++++
output: Alejandro's
Please answer this: I read this background article the other day: 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. I am facing a new situation today: Two related native tribes live thousands of miles away from each other. Ana tribe lives near the South Pole in Antarctica, while Momu tribe lives in Northern Alaska near the North Pole. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which tribe experienced more ozone depletion?
++++++++
Answer: Ana
Question: I read this background article the other day: Windbreaks reduce wind velocity over and around crops. This increases yields through reduced drying of the crop and/or by preventing the crop from toppling in strong wind gusts. I am facing a new situation today: Two farms had winds destroying their crops. Hill farm started installing windbreaks, while Valley farm didn't have the funds to do that so they postponed the project. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which farm prevented the crop from toppling?
Answer:
Hill
