Why does mining have such an impact on the environment? A. Mining only affects the living parts of the environment. B. Because minerals are within the Earth's surface, extraction causes destruction. C. Mining requires the absolute destruction of an area to be cost-effective. D. Areas that are mined can never again sustain plant life. Please select the best answer from the choices provided A B C D
Answer:
B.
Explanation:
The primary environmental effects of mining are on the habitats for wildlife and fisheries, the water cycle, regional temperatures and rainfall patterns, sedimentation, forest loss, and ecological disruption. Thus, option B is correct.
What is the impact of mining on the environment?The effects of mining on the environment include soil, groundwater, and surface water contamination from chemicals produced during mining operations, erosion, sinkhole development, biodiversity loss, and sinkholes.
Mineral extraction from the environment frequently results in imbalances that are harmful to the environment.
Loss of vegetation cover, widespread water body degradation, biodiversity loss, altered land use, increasing social vices and conflicts, high cost of living, and air pollution are some of the negative effects of mining.
Therefore, Because minerals are within the Earth's surface, extraction causes destruction.

Answer:
Soil are tiny bits of substances that contains animal and plants parts as well as nonliving matter such as rocks. They are compressed together by years of new layers of whatever sitting on top of it (New layers of soil, etc). Erosion also assists in the forming of soil as it may take layers of soil from a forest to another for example.

Genetic drift and natural selection can both be mechanisms of evolution. However, they are very different mechanisms. Explain how genetic drift is different from natural selectio
Answer:
Explanation:
Natural selection is the survival of individual organism due to the difference in phenotype. It serves as a basic for evolution as the different heritable characteristics in an individual is due to natural selection. Natural selection acts on the phenotype of the individual which is the visual observance while Genetic drift is the change in frequency of an allele that already exist in a population. This could lead to the allele being selected against and if very small can be lost with time.

Why does light from the sun melt the plastic when light from the desk lamp does not
Answer:
Because the sun gives off a type of light that carries energy, and light from the desk lamp does not.
Explanation:
All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Radiation is one way to transfer heat.
Lamps are electrical devices that use electrical energy in the form of electrical current.

where has the population reached the carrying capacity in the Graph shown above? (need help quick!)
A. point C
B. point B
C. point A
D. point D
Answer:
The correct answer is option D. point D.
Explanation:
Carrying capacity is characterized as the maximum populace size that a domain can continue inconclusively. For most species, there are four factors that factor into figuring the carrying capacity of an individual population: food accessibility, water resources, habitat, and ecological conditions.
In a graph representation of population size in a time period increases until it reaches carrying capacity, carrying capacity is representing in the graph where the increase in curve becomes stable and makes a plateau.
Thus, the correct answer is option D. point D.
Answer:
D point D
Explanation:
DNA: TTA CGC AAC TGG CTA ATT
mRNA: AAU GCG UGA CCG AUU AAC
Identify the type of mutation that occurred in the sequence above and evaluate the significance of these changes. (Will it have any problems in protein synthesis?)
Hint: 1st determine if it was copied to mRNA correctly. When you find the error, that is the mutation. 2nd use the chart if a different amino acid is created, this will determine if it will affect protein synthesis.
Answer:
See the answer below.
Explanation:
The correct mRNA sequence from the DNA according to the base pairing rule should be:
AAU GCG UUG ACC GAU UAA
Instead of:
AAU GCG UGA CCG AUU AAC
This thus means that some of the nucleotide bases have been wrongly substituted.
The most important change is the codon 'UUG' becoming 'UGA', while the former codes for the amino acid leucine, the latter represents a stop codon. A stop codon will result in a non-functional or defective protein.
Hence, the type of mutation is nonsense mutation which results in a sudden cessation of protein synthesis as a result of a codon being prematurely changed to a stop codon.
The significance of this kind of mutation is that a defective on non-functional protein will result which will have a serious phenotypic implication in organisms.

An important example of a "positive feedback loop" in the polar climate system is:
a.Scientists in remote places check on each others instruments.
b.Warming ocean water opens new areas for marine species.
c.Warmer winters cause more plant growth, providing more food.
d.Sea ice melt opens more ocean to sunlight, causing more melt.
Answer: D
Explanation:
A positive feedback loop occurs in nature when the product of a reaction leads to an increase in that reaction.
In choice D melting of sea ice opens more ocean to sunlight which causes more ice to melt which demonstrated a positive feedback loop.
The significant example of a positive feedback loop in the climate system i.e. polar should be at the time when the ice of the sea should be melt that there should be more ocean that results in more melting.
The following information related to the positive feedback loop is:
If the direction varies so it should result in an extra change in a similar direction.Like if we take an example that if there is an increase in the substance concentration so it results in the feedback that generated the continued increase in the concentration.Therefore we can conclude that option d is correct.
All other options seem incorrect.

reasons for increasing demand for energy
Answer:
More people, more demand.
Growing economies increase demand.
Urbanisation increases demand.
The energy mix by fuel type.
Growth in vehicle demand.
This increased demand is caused in part by the increase in population, and by economic development. It is because these areas experienced large-scale economic development, there original energy sources were fossil fuels ,first coal and the oil and gas.
Answer:
Hey!
Some reasons for increasing the demand for energy is...
1) Increasing populations (more demands for heating and fuels)
2) Increasing industries (more factories mean more energy consumption / demand...
3) Increasing availability of different fuels (more choices means more use...)
