[Q]: Please answer correctly the following question related to the paragraph below. In time B would less or more fish DNA be damaged than in time A? Bob was studying about Earth's atmosphere. He found that increased depletion of Earth's ozone layer is a relatively new phenomenon. Most scientists would blame the CFC gases for the depletion of ozone layer. In the early twentieth century ozone layer was relatively stable. Bob labeled that time as time A. But in the late twentieth century situation changed with seasonal depletion of ozone layer. He labeled that time as time B. Hint: Increased solar ultraviolet radiation resulting from the Antarctic ozone hole has reduced marine primary productivity (phytoplankton) by as much as 15% and has started damaging the DNA of some fish. Illegal, unreported, and unregulated fishing, especially the landing of an estimated five to six times more Patagonian toothfish than the regulated fishery, likely affects the sustainability of the stock. Long-line fishing for toothfish causes a high incidence of seabird mortality.

[Q]: Please answer correctly the following question related to the paragraph below. Which zoologist learned more about crypsis? 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. 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.

[Q]: Please answer correctly the following question related to the paragraph below. Will increasing the amount of weeds growing in a garden increase or decrease the health of the plants? Jamie decided he wants to build a garden in his back yard. He finishes planting a nice crop of tomatoes and zucchini and is very happy with himself. About a month later he checks in on his garden only to see a plethora of weeds has grown with his crop. The tomato and zucchini plants are much smaller than he expected and some are even dying. Hint: In addition to insects, weeds have also been a menace to farmers - just ask anyone with a garden how much they hate weeds. They can quickly compete for water and nutrients needed by other plants. Sure, farmers can use herbicides to kill weeds, but do these chemicals also harm the crops? Can biotechnology help with this issue? Some crops have also been genetically engineered to acquire tolerance to the herbicides - allowing the crops to grow, but killing the weeds. But the lack of cost effective herbicides with a broad range of activity - that do not harm crops - is a problem in weed management. Multiple applications of numerous herbicides are routinely needed to control the wide range of weeds that are harmful to crops. And at times these herbicides are being used as a preventive measure that is, spraying to prevent weeds from developing rather than spraying after weeds form. So these chemicals are being added to crops. This practice is followed by mechanical and/or hand weeding to control weeds that are not controlled by the chemicals. Crops that are tolerant of herbicides would obviously be a tremendous benefit to farmers ( Figure above ). The introduction of herbicide tolerant crops has the potential to reduce the number of chemicals needed during a growing season, thereby increasing crop yield due to improved weed management and decreased harm to the crops.

[Q]: Please answer correctly the following question related to the paragraph below. Are the burn rates in Milton currently higher or lower than in Parth? There is currently a wildfire in the city of Milton and another one in the city of Parth. These two cities are on opposite sides of the planet, but both wildfires are nearly identical in terms of scope and intensity. So, when it's daytime in Milton, it's nighttime in Parth. New firefighters in Milton are currently arriving at the scene of the fire as the sun beats down directly above them. They are getting instructions from their boss about what they need to do today and preparing themselves for a long day. Hint: Wildfire intensity increases during daytime hours. For example, burn rates of smoldering logs are up to five times greater during the day because of lower humidity, increased temperatures, and increased wind speeds. Sunlight warms the ground during the day and causes air currents to travel uphill, and downhill during the night as the land cools. Wildfires are fanned by these winds and often follow the air currents over hills and through valleys. United States wildfire operations revolve around a 24-hour fire day that begins at 10:00 a.m. because of the predictable increase in intensity resulting from the daytime warmth.
