I believe it is a combination of polygenic inheritance and environmental factors. Several genes control the height in humans, giving an overall normal distribution. Environmental factors on the other hand such as nutrition smooth out the curve. It is therefore important to note that Human height is a quantitative, or metric trait, that is, a characteristic that is measured in quantity, and is controlled by multiple genes and environmental factors.
RNA polymerase binds to the lac promoter and begins transcribing
the stretch of DNA to messenger RNA.
Therefore, in other words, the stretch of DNA is expressed. The DNA sequence of
the lac promoter 'signals' where the RNA
polymerase will bind and where transcription
will begin. Promoters are found upstream of a gene to be transcribed.

The SWELLING AND BURSTING of animal cells when water enters is called cytolysis. This happens when a cell is placed in a hypotonic<span> solution. pulls away from the cell wall is called plasmolysis. It happens when a plant cell is placed into</span>hypertonic<span> solution. i got this from google if it helps
