It is known as a concentration gradient which in diffusion will always flow from ares of high concentration to areas of low concentrations
So i believe the answer to this is A.
Answer:
Epigenetic effects can be caused by DNA heterochromatin and/or histone silence or activate.
As such, they can different chromosomes or certain chromosomal regions and be responsible for parental imprinting or influencing gene activity in oxidation and reduction.
Patterns of nucleotide demethylation and hypermethylation are often activate when cancer cells are compared to normal cells.
Explanation:
Cells acquire various patterns of gene expression during differentiation to adapt to a changing environment. Epigenetic and genetic alterations are considered as two independent mechanisms that participate in the onset and progression of cancer. Epigenetic mechanisms can be as important for biological events as genetic mechanisms, which do not imply a change in the DNA sequence, but do have an important role in the modification of gene expression.
The word “hydro” means water and “phobic” means away or repel. So, the correct answer would be B, Repels Water
B: nucleus, mitochondria, cell membrane
c and d both have chloroplasts which are unique to plant cells
a is wrong because only plant cells have cell walls
