Construction contributes to soil erosion because;
C. It removes vegetation from the building site.
This would mean a change in base sequence, which is very important for the proteins to carry out their function. It could lead to a mutation and a change in the role of the protein.
The cell membrane is surrounded partially or totally by the Endoplasmic Reticulum which are membranes that extend along the nuclear membrane.
Some scientists hypothesize that the eukaryotic cells are really the result of symbiotic processes!
Specifically, the internal organs of the cells could be a remnant of a symbiotic relationship in which one cell lived inside of another cell. These two cells then both split upon reproduction and eventually the cell inside was reduced to an organelle.
But according to this theory, it is very likely that the prokaryotic cells engaged in a number of symbiotic relationship, and that this actually lead to the emergence of eukaryotic cells!

None of the above. A,B, and C doesn’t make sense and is not related to the question.
