Answers
The characteristics of all organisms and viruses are determined by the instructions carried in nucleic acid.
Further Explanation:
Nucleic acid is an information molecule that plays an important role in the storage and transmission of hereditary information. They are polynucleotide that means it is composed of a long chain of molecules. It is composed of a series of nucleotides that are identical to each other. It is the primary component of the DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). DNA is the double-stranded genetic material that is present in each living cell. RNA is a single-stranded genetic material that helps in many cellular activities such as protein synthesis.
DNA acts as a master blueprint for life. It is present inside all living organism both eukaryotes and prokaryotes. It is present in bacteria and most viruses. RNA is the genetic material that is present in the certain virus. The genetic material helps in determining the class or species of the organism.

d. erosion of soil
Answers
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;
- Habitat destruction
- Soil erosion
- Air pollution from dust particulates
- Pollution (especially from sediments)
- All surface mining techniques negatively affect the environment, though some methods are more damaging than others.
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.

Answers
Large central vacuoles store nutrients and waste products, but they also maintain the plants' structures.
Cell walls also maintain structure and rigidity.
Chloroplasts are used in the process of photosynthesis, which only occurs in plants.
