3. Complete reclamation of mined land is the solution you practiced in this cookie mining lab. What reasoning supports this solution as one that will provide the largest benefits and least costs to society and the environment?
4. Legislation requiring the reclamation of the land makes mining more expensive. How important is this constraint to achieving complete reclamation of mined land?
5. Were the minerals evenly distributed throughout the cookie mines? In the real world, how important is this constraint (distribution of mineral ore) to achieving complete reclamation of mined land?
6. Were you able to restore the land exactly as it was prior to mining? In your experience, would reclamation of mined land be able to restore and stabilize the natural system of the region?
Refining Design
1. How would you refine your mining techniques in this activity in order to maximize reclamation? Be sure to include proposed changes in costs, safety, and restoration of the area.
2. Predict how your refined mining techniques could affect the social and environmental stability of the region.
Mining is the birth of minerals and other geological accouterments of profitable value from deposits on the Earth.
Mining negatively affects the terrain by converting loss of biodiversity, soil corrosion, and impurity of face water, groundwater, and soil. Mining can also spark the conformation of holes. The leakage of chemicals from mining spots can also have mischievous goods on the health of the population living at or around the mining point.In some countries, hidden-trapping companies are anticipated to cleave to recuperation and environmental canons to ensure that the area hidden-trapped is ultimately converted back into its original state. still, violations of similar rules are relatively common.Loss Of Biodiversity
frequently, the worst goods of mining conditioning are observed after the mining process has desisted. The destruction or drastic revision of the pre-mined geography can have a disastrous impact on the biodiversity of that area. Mining leads to a massive niche loss for a diversity of foliage and fauna ranging from soil microorganisms to large mammals. Aboriginal species are most oppressively affected since indeed the fewest dislocations in their niche can affect extermination or put them at high threat of being wiped out. poisons released through mining can wipe out entire populations of sensitive species.legislation related to mining-
There are different kinds of legislation. The legislation that needs land to be restored after mining tends to make mining to be veritably precious as it does so through the duty of some rules and regulations for the hidden-trapping companies.Through this, it handles the responsibility of their land declination and takes back the land to its original form. This process is known to contribute to the fiscal counteraccusations of a company.Why is it important to take land after mining?
Mining is known to be an act that disturbs the land. A lot of mines now are been known to reclaim the face in the course and after mining is completed, and therefore they return the land for useful purposes.
Reclaimed mine lands are known to be veritably beautiful and useful to wildlife and mortal uses.

A species with narrow niches that can survive in a small range of environmental conditions are
A. K-selected species
B. r-selected species
C. Generalist species
D. Specialist species
Answer:
D. Specialist Species
What is the advantage for species to be specialists, and how can they survive in the presence of opportunistic/generalist species?
In the setting of specialized habitats or unique situations, specialized species exist. When those conditions and surroundings change, they must adapt or go extinct, thus they must survive while they still exist.
When compared to generalists, they have the benefit of efficiency, which increases the likelihood of survival and, hence, reproduction within certain settings or situations. The generalists, on the other hand, have the benefit of being able to survive in a larger variety of circumstances and have a higher probability of doing so.
Cactuses, which are plants adapted to dry environments, are an example of specialization. More generalist plant species would typically outcompete cacti in most habitats on Earth, but very few of such species could endure the harsh conditions of a desert.
Extreme environmental conditions, competition for limited resources, and "evolutionary arms races" are some of the pressures that cause specialization. Cheetahs sprint quickly both because their prey moves quickly and because quicker cheetahs will be more effective hunters and more likely to procreate. The advantage of specialization is clear when seen from the standpoint of catching the next meal on a daily basis.
My key argument is that specialization's benefits must always be viewed in the context of the environment that generated the selective pressure that resulted in specialization. Although experts are specialists because they must be, their specializations put them in danger.

Find the equation of the parabola with its focus at (6,2) and its directrix y = 0.
A) y = -1/4(x - 6)² + 1
The equation of the parabola with its focus at (6,2) and its directrix y = 0, is determined as y = 1/4(x - 6)² + 1.
Equation of the parabolaFocus at (6,2) and its directrix y = 0.
Focus equation is given as: (h, k + c) = (6, 2)
Directrix equation is given as: y = k - c = 0
so h = 6, k + c = 2, k - c = 0
Solve the system : k + c = 2 and k - c = 0
add the equations together: k + c + k - c = 2 + 0
2k = 2
k = 1
so k + c = 2,
1 + c = 2
c = 1
4c (y - k) = (x - h)²
4(1)(y - 1) = (x - 6)²
4(y - 1) = (x - 6)²
4y - 4 = (x - 6)²
