False we have three layers of skin.
<h2>Density dependent </h2>
Explanation:
Density dependent inhibition is the process exhibited by most normal (anchorage dependent) animal cells in culture that stop dividing once a critical cell density is reached
The critical density is considerably higher for most cells than the density at which a mono-layer is formed
As cells become more numerous, the cell surface proteins of one cell contact the adjoining cells and they signal each other to stop dividing
Normal cells proliferate until they reach finite density but cancer cells are not sensitive to density dependent inhibition
Answer:
b. orientation dependent
e. located upstream of the gene it controls
Explanation:
Promoter sequences:
These are the sequences present within the DNA on which RNA polymerase binds and start transcription of a gene. These sequences are present directly upstream of transcription initiation site at the 5' end.
Prokaryotes and Eukaryotes both have specific promoter location site which is fixed. So first (a) and Last (f) options of this question are wrong.
This sequence have specific orientation Like TATA box so these are orientation dependent.
These sequences are present directly upstream of transcription initiation site at the 5' end.
Explanation:
the warmclimate meant vast plant growth
