Answer:
chuapamimuñe putito44444444
Answer:
It would be C
Explanation:
Because the colour of a beetle is affected by the allele frequency and therefore changes in alleles as a result of mutations as a result of most likely adaptation
(13) Which part of the digestive system is mainly responsible for absorbing water?

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.

When does molecular breeding give an important advantage over conventional breeding, and how can we exploit this?
Answer:
molecular breeding accelerates the times for genetic improvement
Explanation:
Molecular breeding refers to the techniques used in molecular biology to improve phenotypic features in plants and animals of agronomic and economic interest. Molecular breeding involves many diverse molecular techniques which include, among others, selection assisted by molecular markers (MAS), genome editing techniques (e.g., the CRISPR-Cas genome editing system), quantitative trait loci (QTL) mapping, gene introgression assisted by markers, etc. These techniques can dramatically accelerate breeding programs aimed at improving plant/animal traits and, therefore, they have a fundamental advantage with respect to conventional breeding methods.
What is true of the genetic makeup of all body cells in the human body except for sex cells?

List three reasons why plants and animals are valuable to the local economy. How could the endangered species act help or hurt a local economy?
Answer:
Plants are valuable since they provide our food, materials for shelter, and purify the air (photosynthesis).
Animals such like livestock, supply us with food, fiber and leather.
The Endangered species act can help a local economy because it helps to supply clean air and pure water. It also protects our natural supplies.
How does the tilt of a planet affect its temperature?
Which of the following kingdoms does NOT have members who are heterotrophic? A. Fungi B. Animalia C. Plants D. Protista (Dont send me a file)
Answer:
Plants
Explanation:
This is because plants kingdom are autotrophic that they are producers.
Plants kingdom are producers because the photosynthesized. The have chlorophyll which trap light energy from the sun and uses carbondioxide and water to produce carbohydrates and oxygen is released. Therefore they are not heterotrophic, they did not depend on other kingdom to feed...they are primary producers.
