Humans adapt after prolonged exposure to a constant stimulus because we detect the potentially important changes. It is also because we tend to be curious about the things that are happening around us which we try to adapt and adjust.
A molecule is non-polar if the charge distribution is symmetric and it is polar if the charge distribution is not symmetric.
The answer is B. Strengthens the
cell wall to allow plants to stand up straight and tall
Lignin is a polymer that
constitutes the cell walls of all vascular plants. It provides the mechanical
support for plants and it supplies the strength and rigidity of plant cell walls.
Structural strength provided by lignin helps large trees to reach heights in
excess of 100 m. In the absence of lignin these trees would collapse on themselves.

Addition mutation
This is an addition mutation because the mutated strand has an additional one nucleotide (cytosine) at the end.
Explanation:
This kind of mutation , including deletion mutations, are lethal because they cause a frameshift mutation. Frameshift mutation are a change in codon sequences downstream of a mutation. This causes different amino acids to be coded by the different codons hence changing the translated protein.
