Answer:
The changes in the sequence of nucleotides present within a promoter is a prime cause of the defected transcriptional regulation, which may eventually result in disease. However, not every modification within the sequence of a promoter influences the regulation of transcription, it relies upon the nature and the location of the genetic defect.
When a mutation results within the sequence of a promoter region it may hamper the usual procedures of gene stimulation by affecting the step by step alignment of the transcription factors at the promoter region. Therefore, as a consequence, a mutation within the sequence of a promoter may result in the enhancement or reduction in the level of mRNA and thus protein.

Answer:
B. transporting substances in a cell
Explanation:
Endomembrane system is basically a system or organelles and membranes in eukaryotic cells, which is involved in packaging, modifying and transporting the proteins and lipids across the cell.
Many organelles and membranes play role in this system like lysosomes, endoplasmic reticulum, Golgi bodies and nuclear membrane.
Note: Chloroplasts, Mitochondria and peroxisomes are not part of endomembrane system.
You can see figure depicting endomembrane system for better understanding.
