Select the correct answer. Which statement about natural selection is true? A. Natural selection and evolution are two terms for
Masja [62]

Answer:

C. Natural selection is the process by which organisms with more beneficial traits are more likely to survive and reproduce.

Explanation:

Natural selection is an evolutional process by which species of living organisms with stronger or more beneficial traits have higher chances of survival and reproduction. In other words, it is the process by which organisms adapt and survive.

Organisms in a population are all different in their own ways. And those with characteristics or traits better suited for the environment are more likely to survive than those without. The selection prefers more beneficial traits and not wholly on the superiority of the organism. So, the survival and reproduction chance of an organism depends on the presence of traits beneficial to the environment, which is how nature selects. And in this process, those selected will dominate the population while those rejected will be reduced or even die.

Thus, the correct answer is option C.

Which renewable resource is not safe for the environment and why?
Karo-lina-s [1.5K]

Answer: Biomass

Biomass produces gas or many sorts of waste products which are mostly used in burning and cooking. It is plant or animal material used as fuel to produce electricity or heat. Examples are wood, energy crops, and waste from forests, yards, or farms.

But the reason why it can be harmful is because biomass can produce gases like methane. Methane is a  greenhouse gas which can harm the environment and reduce the ozone layer that stops harmful UV light from reaching the earth atmosphere.

Many different organisms live in Amanda’s garden. The diagram shows a simple food web of some of the organisms in her garden.
Alex787 [66]

Answer:

The snakes keep the mice from overpopulating, which could deplete their resources.

Explanation:

The mice and the moles are not competing against each other as they feed on different food. The problem is that if the mice population is not regulated, their very quick reproduction will cause overpopulation in very short space of time. The more mice there will be , the more food will be needed, so very soon the resources will be depleted, resulting in collapse of the mice population. This is where the snakes come in action, as they eat mice, so they are the ones that control and keep their population stable, thus not allowing the mice to overpopulate the area and destroy themselves.

What is the impact of developing and using rock, mineral, and energy resources on earth's living and non living systems
77julia77 [94]

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:

<u>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</u>. 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.

<u>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.</u> 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. <u>They may then end up disposing of them in rivers or coastal waters.</u>

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 <u>contamination of soils due to mineral materials and toxic substances</u>.

<u>Also, the production and use of energy is the main cause, together with transportation, of greenhouse gas emissions, the gases responsible for climate change</u>. Consequences of climate change are increased temperatures, rising sea levels and reduced rainfall.

The current model of generation, transport and consumption, <u>absolutely dependent on fossil fuels, is unsustainable</u>. 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 <u>the cause of the deterioration and destruction of forests, lakes and other ecosystems</u>. Another example are the N<u>uclear power plants which produce high-level radioactive wast</u>e (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.
