Which molecule regulates how the organism looks and acts?
Answer:
In a cell, proteins can act as enzymes, structural features, pigments, and a host of other functions, including regulating the expression of other genes. This expression of genes leads to how an organism looks – its phenotype.
Explanation:
Gene regulation creates different types of proteins which make the structure of cell and organism looks, so the gene is responsible for looks and acts.
What is gene regulation?Gene regulation is a critical component of proper development. During development, genes are switched on and off in diverse patterns to make a brain cell appear and perform differently from a liver cell or a muscle cell, for example.
Gene control also enables cells to respond swiftly to environmental changes. Genetic differences can result from gene variants (also known as mutations) or through a natural process.
Genetic information is reorganized when a cell prepares to divide (known as genetic recombination). Different features in an organism can be introduced via genetic differences that modify gene activity or protein function.
Therefore gene is responsible for how an organism looks and act, it creates different proteins to make a cell.

Victor put a match on a balance and found that its mass was 6.0 grams. Then he lit the match and put it out after a few seconds.
He put the partially burned match on the balance again. This time, its mass was 4.5 grams.
Which of the following best explains what happened as the match burned?
A.
Some of the mass was destroyed by the fire.
B.
The mass of the match combined with the mass of the fire.
C.
The matter moved to a different part of the match.
D.
Some of the matter changed from solid to gas and went into the air.
Answer: It releases oxygen and heat. The answer is C
Stored inside the match head is another chemical called “potassium chlorate”. When it gets hot, it releases a lot of extra oxygen and heat. This makes the match head burn quickly and strongly. When you put it all together the heat, the fuel, and the oxygen you get a flame. Matter does not go when something is set on fire. Matter is always the same. Burning is a chemical process. The flames are caused as a result of a fuel undergoing combustion (burning). (CC BY-SA 2.5; Einar Helland Berger for fire and Walter Siegmund for ash).

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.

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.
