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.

Can someone please help me answer this question? Thank you.
Answer:
The correct answer is -
C is parent cell
A is under meiosis
B is a sex cell
Explanation:
In the given question, the diagram shows three different cells in which the cell C is the parent cell that is about to undergo meiosis that can be identified by the quantity or numbers of chromosomes present in the cell which is highest among all.
The cell that is already in the meiosis is cell A, it is the cell that is produced after meiosis 1 in the meiosis cell division as it has half number of chromosomes to parent cells.
The sex cell or gamete is cell C that has a haploid number of chromosomes which makes this process reduction division

Can a person with Rh-blood safely receive blood from either Rh+ or Rh-blood?
Answer:
Yes
Explanation:
Since the person already has Rh in their blood, it does not matter whether the donated blood is Rh+ or Rh-. getting Rh- blood for a Rh+ person is not harmful, unlike when it is vice versa.

4. Darwin and Wallace both gathered a large number of observations and facts on which they based
their theories. Which of the following types of evidence was NOT part of the evidence they gathered?
a. fossil evidence
b. anatomical evidence
C. geographical distribution
d. genetic evidence
Answer:
c I hope I got it but have a good day
The type of evidence that should not be part of should be genetic evidence.
What is genetic evidence?It is the evidence where it predicted the no of human ancestors. Here the relation between the genetic diversity & the size of the population should be considered. So based on this, it received large no of observations and facts related to the fossil, anatomical, and the geographical evidence
Therefore, the option d is correct.

Explain the role of aquaporins in the rapid movement of water through some cells
Answer:
In the early 1990s, aquaporins were discovered, and it was found that they can selectively control water movement into and out of cells. One of the critical functions of aquaporins is that while they allow the passage of water they prevent the passage of ions.
what do birds short necks help them to do? pls help :/
Explanation:
Most diving birds have (relatively) long necks and shorts legs, although their necks aren't as long as say herons, storks or egrets. Take the common loon for instance. Their necks can be up to half as long as their bodies but their legs are so short and set so far back that they are very awkward on land.
Answer: they can extend it out and twist their head around so easy

Answer:
Explanation about Commensalism Mutualism, Parasitism, Competition, and Predation are given below.
Explanation:
There are various symbiotic relationship formed between the organisms present in the environment. These relationships are Commensalism Mutualism, Parasitism, Competition, and Predation. In Commensalism relationship, one organisms gets benefits while the other neither get benefit nor harm. In mutualism, both organisms gets benefits from one another. In Parasitism, one organism get benefits and the other get harmed. In Competition, both organisms cause harm to one another and both are damaged through their actions and in Predation, one organism is benefited by killing the other organism to feed itself.
