Answer:
The advantage of small cell size is that substances like organic molecules and ions can diffuse easily into the cells whereas wastes can diffuse easily out of the cells.
The correct answer is A - eventually a predatory species may utilize it as an energy source and its negative impact on the ecosystem will be decreased but until then, the pad trees will suffer the consequences.
Epigenetics is the study of how DNA methylation and alterations to chromosomal proteins affect a gene or group of genes express themselves. For changes in a gene's expression, both of these are need.
In a biological process called DNA methylation, methyl groups are added to the DNA molecule. A DNA segment's activity can be altered by methylation without the sequence changing. DNA methylation usually inhibits transcription of genes when it occurs in a gene promoter.
Epigenetics literally translates to "along with changes in genetic sequence." Any procedure that modifies gene activity without altering DNA sequence and results in modifications that can be passed on to daughter cells is now included in the term. Is called Epigenetics.
