Open-pit mining creates a large hole in the ground after minerals are removed from the surface. Which statement best describes an environmental consequence of this process?
Heavy metals are released into surrounding soil, poisoning local vegetation.
High salinity of wastewater reduces soil fertility and growth of vegetation.
Billions of gallons of water are pulled from surrounding ecosystems.
Wastewater is contaminated with oil and becomes sludge in landfills.
Answers
Answer: (A) Heavy metals are released into surrounding soil, poisoning local vegetation.
Explanation: Open-pit mining falls under the surface mining category in the lesson 01.07 page 3/8 under the affects of surface mining the only one that is in the multiple choice questionnaire is "Heavy metals are released into surrounding soil". (don't know how much this helps since I'm 7 days late but hey this is a new curriculum and I've had trouble finding answers on brainy so why not contribute for once ¯\_(ツ)_/¯ )
The correct statement that best describes an environmental consequence of open-pit mining is that heavy metals are released into the surrounding soil, poisoning local vegetation.
The large hole left by open-pit mining becomes filled with water during heavy rains with heavy metals dissolving in the water to form solutions.These solutions percolate the surrounding soil and when they are taken up by the vegetation on the soil, the plants become poisoned by the heavy metals.In other words, the hole created by open-pit mining serves as an avenue for heavy metals to get into the surrounding soil and gets into the food chain through the plants.

be?
A: FF
B: Ff
C: ff
D: cannot determine
*red circle is affected female*
*blue circle is normal female*
*red square is affected male*
*blue square is normal male*
Answers
In the pedigree showing the transmission of Cystic Fibrosis, the genotype of the marked woman will be FF or Ff. Thus, options A and B are correct.
What is a pedigree?Pedigree represents the heritable phenotypic trait in the form of charts and diagrams. Cystic Fibrosis disease is inherited by the autosomal recessive alleles and is possible only if the genotype is ff.
The genotype for the woman being normal should not have recessive alleles and only can be heterozygous or purebred dominant. It is possible only if the genotype is Ff and ff.
Therefore, the genotype of the indicated woman will be Ff and ff.

Why do living things need water, food, and space to live? To maintain homeostasis.
Answers
2.)Water- You could only survive for about three days without water. You get water from the fluids you drink and the food you eat.
3.)Air- Air is a mixture of several different gases, including oxygen and carbon dioxide. Most living things use oxygen in the chemical process that releases energy from food. Oxygen may come from the air or may be dissolved in water.
4.)Habitat- All organisms need a place to live that contains all of the things they need to survive. Some organisms, such as elephants, require a large amount of space. Other organisms may live their entire life in one place.

____________________________________ use reduced, preformed organic molecules (usually from other organisms) as carbon sources, obtain energy from the oxidation of organic compounds, and use reduced organic compounds as their electron source.
Answers
Answer:
Heterotrophs
Explanation:
Heterotroph, in ecology, is an organism that consumes other organisms in a food chain. They acquire their energy by the controlled breakdown of preexisting organic molecules, or food.
¹All heterotrophs, use organic materials as their sole source of carbon. Heterotrophs use preformed organic compounds as their source of carbon. (Source: Brittanica)
Metabolic cycles in general—the extraction by organisms of useful ²energy and food molecules from environmental source material—can be described in terms of oxidation-reduction reactions
Heterotrophs can be organotrophs or lithotrophs. Organotrophs exploit reduced carbon compounds as electron sources, like carbohydrates, fats, and proteins from plants and animals. On the other hand, lithoheterotrophs use inorganic compounds, such as ammonium, nitrite, or sulfur, to obtain electrons.
how does the liver help in maintaining homeostasis
Answers
Answer:
The liver plays a major role in blood glucose homeostasis by maintaining a balance between the uptake and storage of glucose via glycogenolysis and gluconeogenesis. The liver is the primary organ for glucose metabolism.
Glycogenolysis: Glycogenolysis is the biochemical pathway in which glycogen breaks down into glucose-1-phosphate and glycogen.
Gluconeogenesis: Gluconeogenesis is the synthesis of glucose from non-sugar precursors, such as lactate, pyruvate, and the carbon skeleton of glucogenic amino acids.

This element separates it hastily and practically from the other significant sort of endoplasmic reticulum (emergency room), the smooth endoplasmic reticulum (SER), which needs ribosomes and is associated with the union and stockpiling of lipids. RER happens in both creature and plant cells.
