Identify the kind of response to the following argument: Argument: In nature, a species is more likely to survive when its weak members die out, so we should let the weak in our society die out. Response: In nature, a species is more likely to survive when it lives in its natural habitat, so we should live in our natural habitat. A. refutation by parallel reasoning B. refutation by reduction to absurdity C. refutation by counterexample D. not a refutation
Answer:
A. refutation by parallel reasoning
Explanation:
A refutation by parallel reasoning is an analogical inference between two arguments. This type of refutation occurs when an argument is invalidated by showing that the argument's conclusion is not supported by its premises, thereby the structure of the argument is incorrect. The parallel argument should demonstrate that the premises of the target argument are founded in a fallacy or don't provide a strong enough rationale to support/accept its conclusion.
What is the impact of developing and using rock, mineral, and energy resources on earth's living and non living systems
Answer: The use of rock, mining and energy production contaminates the environment by affecting the abiotic land mass. And therefore, by contaminating the habitat, the living beings that live there are harmed.
Explanation:
Mineral and rock extraction, transport and processing comprise actions that produce environmental impacts because it produces a certain disturbance to the surface and underlying strata, as well as to aquifers. These impacts can be short-lived, lasting as long as the mine is operational, or they can persist after mine development has been completed.
Major impacts include:
Contamination of soil, vegetation, drainages, rivers and groundwater aquifers contamination from leaking tailing piles and slurry ponds. If not properly treated, effluent from surface or subway mine water disposal can be highly acidic, and will contaminate surface waters and shallow groundwater with heavy metals, nitrates or oil from equipment, reducing local water supplies. During surface mining, movement and stockpiling of overburden, constructions or covering of soils alter rivers, drainages and coastal areas. Surface disturbance caused by access roads, pits, and site preparation.Noise and emissions from the operation of equipment.Air pollution, atmospheric dust from traffic, excavation, drilling and site clearing. Atmospheric particulates come from blasting, excavation and earth moving, transportation or any operations that occur on the surface of subway mines.Removal of rock strata can disrupt the continuity of the local aquifer, and cause interconnections and contamination between groundwater.Both surface and subway mining include a drainage of the mine area and discharge of mine water, the removal and storage/disposal of large volumes of waste and the transfer and processing of minerals or construction materials. This requires the use of diesel or electric mining and haulage equipment. Transportation of ore within the mine area and to processing facilities may use trucks, conveyors, rail, polyduct or conveyor belt which are vehicles that emit large amounts of carbon dioxide.
Processing plants may be located in mountainous regions and so may have difficulty disposing of production wastes and other pollutants. They may then end up disposing of them in rivers or coastal waters.
The land at the surface of the mines will be unstable, there will be fracturing and subsidence, it will modificate soils, vegetation, rivers, wildlife habitat, wetlands, causing a temporary or permanent loss of land productivity, and contamination of soils due to mineral materials and toxic substances.
Also, the production and use of energy is the main cause, together with transportation, of greenhouse gas emissions, the gases responsible for climate change. Consequences of climate change are increased temperatures, rising sea levels and reduced rainfall.
The current model of generation, transport and consumption, absolutely dependent on fossil fuels, is unsustainable. The chemical products emitted, mainly from coal and oil-derived thermal power plants, are transported by the wind and deposited by rainfall thousands of kilometers away from their origin, causing "acid rain", which is the cause of the deterioration and destruction of forests, lakes and other ecosystems. Another example are the Nuclear power plants which produce high-level radioactive waste (long-lived, highly radioactive), which poses a constant threat to the environment due to the current inability to manage it.
Thus, the use of rock, mining and energy production contaminates the environment by affecting the abiotic land mass. And therefore, by contaminating the habitat, the living beings that live there are harmed.
The impact of developing and using rock, mineral, and energy resources will be:
loss of biodiversity, soil erosion, and contamination of surface water, groundwater, and soil.
Impact of Minerals:They help us to develop new technologies and are used in our everyday lives. Our use of rocks and minerals includes as building material, cosmetics, cars, roads, and appliances. In order maintain a healthy lifestyle and strengthen the body, humans need to consume minerals daily. Soil, rocks, and minerals provide essential metals and other materials for agriculture, manufacturing, and building.

Explanation:
Due to its location, Hawaii does not have very many land birds. The Hawaiian honeycreepers are a favorite for many ornithologists. There are over 50 species of honeycreepers that can all be traced back to one ancestor. The level of diversity in an ecosystem can be determined by the frequency of speciation and extinction.
a) Describe speciation and identify two possible prezygotic barriers of the Hawaiian honeycreepers that contribute to speciation.
b) If the Hawaiian honeycreepers became extinct, explain how the newly available niches could lead to speciation.
Answer:
In speciation, organisms evolved with the passage of time.
Explanation:
Speciation is the evolutionary process in which populations of species evolve with the passage of time to become different species from the original one. Temporal isolation and gametic isolation are two possible prezygotic barriers of the Hawaiian honeycreepers that contribute to occur speciation. The newly available niches could lead to speciation of that organisms that tolerate the Hawaiian climatic conditions when the extinction of Hawaiian honeycreepers occurs. The new organisms used the available resources such as food and space etc and increase its population.

Cory states the following argument about the evolution of aardvarks and anteaters.
"Aardvarks and anteaters both use long, sticky tongues to capture and eat ants or termites. Aardvarks are native to Africa, while anteaters are native to the Americas. However, their similarities provide evidence that both groups of species evolved from a common ancestor that used its tongue to eat ant-like insects."
Which claim, if supported by evidence, would provide the strongest counter-argument AGAINST Cory's argument?
A. The tongues and diet of aardvarks and anteaters are an example of convergent evolution.
B. The tongues and diet of aardvarks and anteaters are an example of adaptive radiation.
C. The Americas and Africa were once joined together, and animals roamed freely between the two lands.
D. A long, sticky tongue evolved in response to the tunneling behavior of ants, an example of coevolution.

Explanation:
because solid metals will sink when placed on top of whole milk.
Metal is denser than milk is the property of density, these are true. Thus option A is correct.
What is density ?The density can be defined as its mass per volume and it is the ratio between mass and volume, where how much stuff of an object has in a unit volume.
Density is a calculation of matter, where it shows how tightly matter is mixed together, density was discovered by the Greek scientist Archimedes
The density of an object can be represented as the mass (m) can be divided by the volume (v)
Density = Mass/Volume
The SI unit of density is represented as kilogram per cubic meter (kg/m3) or in cgs unit it can be represented as grams per cubic centimeter (g/cm3).
Thus option A is correct.
