Depth of groundwater and distance from nearby water sources must be considered otherwise rain water will carry trash into the water bodies or nutrients from decomposed trash will seep into the water, causing eutrophication.
Right receptor protein on the surface of the target cell or in cell plasma is required. There are three major types of receptors in cell:
1. Channel receptors- <span>neurotransmitters.</span>
2. Receptor tyrosine kinases-protein expression
3. G protein coupled receptors-<span>detect </span>substances<span> outside the </span>cell
Initiation: Replication begins at a specific location called as OriC, at which some initiator protein bind and cause unwinding
Elongation: New DNA stand grows, one base pair at a time.
Termination: The two new double helices replace the older ones and the last primer strand is removed, followed by proofreading.
The answer is C to move proteins and other substances through the cell
