Subsurface mining is one of the types of mining, which is done when minerals that are mined are present below the surface of the earth. This is done because the minerals cannot be obtained from the surface level. Then, in that case, subsurface mining is done.
It is done by constructing a reinforced tunnel down the surface to the place where the mineral resource is present.
Answer:
B.
Explanation:
basically when the stem cell in the crypts divides they formed daughter cells. One of the daughters from each of the original divided stem cells usually divides to form another stem cell, while the rest forms transit amplifying cell.These amplifying cells are capable of dividing multiple times until they are evenly differentiated(designated to specific function) e.g top globlet cells, enterocytes, tuft cells etc.
Answer:
b+ svn+ and b svn
Explanation:
Linked genes may be defined as the genes that are present on the same chromosomes. These genes are physically close together and can be inherited as a single unit in the progeny.
The bent wings (b) and shaven bristles (svn) are completely linked means that they can inherit as a single unit in the progeny. The cross between bb svnsvn and b+b+ svn+svn+ leads to the gamete formation of the genotype b+ svn+ and b svn in their off spring.
false would be your answer
I assume you mean how plastic bags are less harmful than paper backs. Despite its low durability, one advantage of paper is that it decomposes much more quickly than plastic, and therefore it is less likely to be a source of litter and pose a risk to wildlife. Paper is also more widely recyclable, while plastic bags can take between 400 and 1,000 years to decompose.
