Answer;
B. improved ecosystem health
Explanation;
-Surface mining is a method of extracting minerals near the surface of the Earth. The three most common types of surface mining are open-pit mining, strip mining, and quarrying.
-The environmental impact of mining includes erosion, formation of sinkholes, loss of biodiversity, and contamination of soil, groundwater, and surface water by chemicals from mining processes.The environmental effects of surface mining include;
An improved ecosystem cannot be a possible consequence of surface mining.
Further Explanation:
Surface mining is a process of extraction of mineral beneath the surface of earth or from the earth's surface. This process is used to recover the gravel, coal, metal, iron, sand, and stones. There five different kinds of surface mining with a particular change depend upon the mineral that is being extracted from the earth’s surface. The air gets contaminated with carbon monoxide, hydrocarbons, sulfur oxide, nitrogen oxide, and ground-level ozone during the process of surface mining.
The mining process loses the soil particle, which is responsible for large scale erosion. These eroded particles, when scatters in the ecosystem, cause destruction of fauna and flora. Though the mining process releases harmful particles in the environment and has many negative consequences, thus, it cannot be taken as a factor that improves the ecosystem.

. Complex sugars are called polysaccharides.
Option C is correct
Monosaccharides are the simplest form of sugar, and they cannot be broken down any further. Disaccharides are made up of two monosaccharides joined together, and polysaccharides are made up of many monosaccharides joined together.
Some examples of polysaccharides include starch, cellulose, and glycogen. Starch is the main form of storage carbohydrate in plants, and it is made up of glucose molecules. Cellulose is the main structural component of plant cell walls, and it is also made up of glucose molecules. Glycogen is the main form of storage carbohydrate in animals, and it is also made up of glucose molecules.

stable
Answer: The correct answer for the fill in the blank is High.
Hypotonic solution is the one, which contains less concentration of solute (like salt) as compared to the solvent (water).
In other words, in a hypotonic solution, the concentration of solvent is higher than the concentration of solutes.
Thus, the relative concentration of water ( which is a solvent) in a hypotonic solution is high.
The relative concentration of water in a hypotonic solution ishigh. The correct answer between all the choices given is the firstchoice. I am hoping that this answer has satisfied your query about and it willbe able to help you.
Answer:
A simple sugar, a phosphate group, and a nitrogen base
b. carbohydrates and RNA
c. protein and nucleic acids
d. carbohydrates and nucleic acids
The answer is C.
A virus is made up of or consists of a nucleic acid in varying quantity which may either be RNA or DNA.
The nucleic acid is surrounded by a protein shell called a capsid. The word capsid comes from the Latin word capsa which means box.The capsid and the nucleic acid within it are together referred to as nucleoprotein.The capsid is made up of small sub units called capsomeres.
In many viruses, the nucleoprotein makes up the whole virus. More complex viruses have one or more further enclosing structures also made mostly of protein. These structures are referred to as envelopes and each envelop is specific to a particular virus.
c. protein and nucleic acids
Answer:
The correct answer would be cell organelles.
Cell organelles refer to the sub-cellular components which perform specific functions. For example, ribosomes, mitochondria, nucleus et cetera.
Most of the cell organelles are common to all types of cells whether unicellular organisms or cells of multicellular organisms.
For example, ribosomes, lysosomes, vacuoles et cetera are common in all cells.
