Nitrogen Fixation: Root and Bacteria Interactions. Nitrogen is an important macronutrient because it is part of nucleic acids and proteins. ... The most important source of BNF is the symbiotic interaction between soil bacteria and legume plants, including many crops important to humans.
After mining, to reclaim the land, the depression is filled with rocks then the top is filled with loosely graded soil. Introduction of early succession plants is important before big trees can grow. The early succession plants help in the breaking down of the rocks into soil hence making the topsoil deeper to support trees.

would know that a cell under microscope is prokaryote because it lacks nucleus
cells. Prokaryote is a single celled organism. It’s cell structure is composed
of flagellum, cell membrane, cell wall, cytoplasm, ribosome, nucleoid, and
glycocalyx. Flagellum’s function is to aid cellular locomotion but is only for
selected types of prokaryotes. Cell wall covers the outer part to protect the
bacteria cells. Nucleid is the area that contains the DNA of the bacteria. Cell
membrane regulates the flow of the substances in and out of the cell. Cytoplasm
contains salts and other organic molecules. Ribosomes is responsible of protein
production.</span>
Answer: The correct answer is- C) vacuole.
Large central Vacuole is a specialized fluid filled organelle, present only in plant cell. It is primarily involved in providing support and shape to the plant cell by maintaining the turgor pressure ( a hydrostatic force that is produced due to the cell contents against the inner side of the cell wall). The central vacuole stores water ( that flows through osmosis) and maintains turgor pressure in a plant cell.
Turgor pressure provides mechanical support and helps in the growth and development of plant.
Answer:
Hi, there the answer is
C.It is a frameshift mutation that changes many amino acids.
Explanation:
Due to the triplet nature of gene expression by codons, the insertion of the single Adenine nucleotide will disrupt the reading frame of the gene (frameshift mutation), such that it is no longer evenly divisible by three.
Thus, resulting in a completely different translated protein from the original.
Hope this helps :)
