a essay explaining why i choose a certain university
Answer:
Because the facilities here for my subject are second to none” – this shows that your subject has been at the forefront of your mind when making a sensible choice of university, again demonstrating your level of commitment to it. You can mention specific facilities to show that you’ve read into it thoroughly.
“Because I liked the approach this university takes to my course” – even within the same subject, every university takes a slightly different approach to the way it’s taught and structured. The university question is another good opportunity to show that you’ve really thought about the course and gone to the effort of finding a university whose approach to the subject you agree with. You can even name specific modules that set this university’s course apart from the others offering the same subject.
Along similar lines, you could also mention the university’s great reputation for your subject, or the presence of certain lecturers you feel inspired by (though don’t let this last point dominate your answer; lecturers often move about or go on sabbatical, so even if there’s a particular academic you admire, they may not end up teaching you).

Lloyd’s lab partner is looking down into a test tube while he heats the contents by using a flame. Which action should Lloyd recommend to his partner if heating must continue?
Wear safety goggles while looking into the opening of the test tube.
Cover the opening of the test tube so that no materials can boil out of it.
Move the test tube so that the opening is pointing away from all students.
Put the test tube in a hot water bath so that no water can enter its opening.
The correct action that Lloyd should recommend to his partner who was looking down into the test tube if heating must continue would be to move the test tube so that the opening is pointing away from all students.
Wearing safety goggles (and looking directly down at the test tube) might not be enough to protect Lloyd's partner nor other students in case the content of the test tube splashes out.Covering the test tube might hinder any generated gas as a result of heating from escaping safely into the air and this might cause an explosion.Putting the test tube in a hot water bath so that water can enter its opening will definitely affect the reaction and prevent them from getting accurate results/observations.Hence, the most correct action would be for Lloyd's partner to move the test tube so that the opening is pointing away from all students.

D. no longer serves a function.
Answer:a
Explanation:a
An analogous structure is one that has the same function in multiple organisms but evolved independently each time, without a common ancestor. The correct option is C.
What are analogous organs?Analogous organs are those organs that are different in different organisms and have grown in different times and have nothing in common, but they function similarly. The animals are anatomically very different, but some organs have the same functions.
Examples of analogous organs are:
The wings of a bat, a bird, and an insect.The fin of a dolphin and a shark.Sweet potato and potato.Thus, the correct option is C. has the same function in multiple organisms but evolved independently each time, without a common ancestor.

Fracking uses highly pressurized fluids, such as water mixed with sand and chemicals, to drive open cracks that exist in underground rock. Which
statement best describes an environmental consequence of this process?
• Chemicals added to the liquid can contaminate groundwater.
O Wastewater is contaminated with oil and becomes sludge in landfills.
Water vapor is released into the air, which is considered a greenhouse gas.
Heavy metals are released into surrounding soil, poisoning local vegetation
The correct answer is that chemicals added to the liquid can contaminate groundwater.
Fracking is a method of drilling fossil energy resources, which requires a lot of water and consumes local water resources. It is pumped with high pressure water, sand and chemicals, causing high pressure to block the porous rock and release gas.
The water spill itself destroys nature from the drilling site, and may even cause earthquakes, especially due to the pumping of abundant wastewater into porous rock types such as limestone. For example, Oklahoma appears to have become a special earthquake risk area. The biggest impact of water distortion is on groundwater. In Wyoming, USA, the same chemicals found in groundwater have been found in groundwater, and some of them are toxic or carcinogenic.

Explanation:
Moosehead Lake in Maine is a beautiful lake, spanning 74,890 acres with a maximum depth of 246 feet. The most sought-after fish to be found in Moosehead Lake are: Landlocked salmon, lake trout, brook trout, and burbot. According to Tim Obrey, a regional fisheries biologist with the Maine Department of Inland Fisheries and Wildlife, the fishing at Moosehead declined from phenomenal to just "really good" during the late 1980s, but has rebounded due to careful management. This table shows the populations of three major fish in Moosehead Lake over a 30 year period. Moosehead Lake was illegally stocked with smallmouth bass in 1970. Fish Populations in Moosehead Lake Year Smallmouth Bass Salmon Lake Trout
Smelts are the primary food source for lake trout and salmon in Moosehead. In the late 1980s, we documented a dramatic increase in the abundance of wild lake trout in Moosehead Lake. Swelling lake trout numbers taxed the forage base and the smelt population took a dive. What would be appropriate action for Wildlife Management to make to correct the problem? Choose ALL that apply.
B) One hundred small, one-hectare size areas should be conserved
C) Native species should be maintained or planted within the greenspace to promote biodiversity.
D) Exotic species should be cultivated and planted to increase biodiversity in the protected greenspace.
E) The majority of the secondary consumers should be removed from the greenspaces to promote an increase in lower levels of the food chain.
(WILL GIVE BRAINLIEST WHOEVER CAN ANSWER RIGHT!!!!!!)
When one of the trophic web links disappears, it affects the whole chain. In management programs it is important to consider these consequences to keep the whole ecosystem equilibrium. In the exposed situation, Native species should be maintained or planted within the greenspace to promote biodiversity and The majority of the secondary consumers should be removed from the greenspaces to promote an increase in lower levels of the food chain.
--------------------------------------
The trophic chain is the energy transference process that involves different organisms, from autotroph or producers, to the consumers or decomposers.
The disappearance of one link affects the whole system. The direct superior link does not have enough food supply, while the immediately anterior link is beneficiated for not being eaten by its predator. And finally, as this last link will overgrow, it will consume greater quantities of its food, causing a decrease in its anterior link. Top-down control refers to scenarios where superior predators control the structure and dynamic of an ecosystem.
It is necessary and significant to consider these modifications in the whole ecosystem while planning management actions to keep an equilibrium.
In the exposed example we know that the most wanted species are
Landlocked salmon, lake trout → which increased its population size sharply over the last yearsbrook trout, and burbotSmelts, which are the primary food source for lake trout and salmon, decreased in population size significantly.
Finally we know that smallmouth bass was introduced in 1970.
This information suggests that the decrease in smelts' population is due to the predation of the species by the lake trout, which population increased sharply in size. The change on smelts' population size, might affect the blook trout and salmon populations, that also feed on semelts, and might also affect other species occupying inferior levels.
When implementing a management program, it would be necessary to promote biodiversity by growing native species in greenspaces and ensure their survival and reproductive succes. In the exposed case, it is necessary to preserve smelts' population, so it would be also necessary to remove from these green spaces the secondary consumers -trouts and salmon- that feed on them, to ensure the smelts' population growth and recovery.
