Surface mining destroys vegetation and affects soil strata. Mining disrupts to topsoil microorganisms. Reclamation operations that dilute topsoil with subsoils can degrade soil.
Surface mining is a type of mining in which the soil and rock covering the mineral deposits are removed. It's the other way to mine underground. The rock on top is left in place, and the needed minerals are taken out through shafts or tunnels.
Surface mining can hurt fish and aquatic resources by causing erosion and sedimentation, drying up wetlands, rerouting and channelizing streams, and putting toxic chemicals into the surface water and aquifers.
This will further disrupt plant life on surface.

Answer:
Surface mining destroys all plant life in the area the mine occupies. Plants living in the area where the surface mine is to be located are removed. ... All three types of mines cause some damage to the environment.

The correct order of events during the synthesis of a specific protein would be:
The first step in the synthesis of protein is that genetic information for s specific trait on DNA is transcribed to messenger RNA in a process known as transcription.
Thereafter, the mRNA moves into the cytoplasm and gets attached to the ribosome. Another RNA, a tRNA that carries the amino acids that correspond to the genetic codes on the mRNA, moves to bind to the mRNA using its anticodon.
The codons are read in groups of 3s and the amino acids corresponding to each codon will get released from the tRNA at their respective turns. The released amino acids are joined together by a peptidebond to form protein.

Answer:
The correct order is: b), e), a), c) and d)
Explanation:
Messenger RNA leaves the cell nucleus and moves through the cytoplasm. During protein synthesis, the ribosome reads the base sequence of messenger RNA, and uses DNA to translate each codon triplet, into its respective amino acid. The RNA is synthesized in the nucleus and then later leaves the cytoplasm for the translation process. In general terms, DNA is transcribed into a messenger RNA molecule, so that a certain protein is produced
c. volume, surface area
b. width, surface area
d. none of these
The study of the cell is called cell biology. There are two types of cells and these are unicellular and multicellular.
The correct answer is option C which is volume and surface area.
The structural and functional unit of all living organisms. All living organism is made up of cell.
According to the question, The correct answer is option C.
As a cell grows, its VOLUME increases more than its SURFACE AREA.
Hence, the correct answer is option C.
For more information about the cell, refer to the link:-
B. zymogenic cells
C. mucous neck cells
D. enteroendocrine cells
Parietal cells produce intrinsic factor, which is important for the absorption of vitamin B12.
The correct answer to the given question is option A.
Intrinsic factor is a protein produced by parietal cells in the stomach.
It plays a crucial role in the absorption of vitamin B12 in the small intestine. Without intrinsic factor, vitamin B12 cannot be absorbed and can lead to a condition called pernicious anemia.
