<em>D is the correct answer because osmosis is the movement of a solvent ( mainly water ) from area of higher concentration to that of lower concentration through a semi-permeable membrane ..</em>
Answer:
Option (A) and (C).
Explanation:
Gene regulatory mechanism are important for the regulation of the transcription and proper expression of genes. Different regulatory mechanisms are present in prokaryotes and eukaryotes.
The prokaryotes do not require the multiple general transcription factors where as the eukaryotes have different transcription factors like TFIID, TFIIH and TFIIA. The DNA is packed around the histone protein that form chromatin in eukaryotes. The chromatin packaging includes methylation, ribosylation with the help of enhancers and silencors. The chromatin is absent in case of prokaryotes.
Thus, the correct answer is Option (A) and (C).
Which statement below BEST summarizes the role of the DNA molecule in cells. The answer is C.
Answer:
C₂H₄
Explanation:
A hydrocarbon with a double bond is called an alkene. The general formula for an alkene is CₙH₂ₙ where as the n represents the number of carbons.
Taking your problem as an example:
C₂H₄ has 2 carbons, as indicated by the subscript beside the chemical symbol of Carbon.
if C = 2 then n = 2
CₙH₂ₙ = C₂H₂₍₂) = C₂H₄
Answer:
A can be right answer because reproduction is completely based on cells where as others r n{t primary function
