Help Question 1 (3 points)
We have been learning about mutation of genes vs. epigenetic modification of genes
in class. Choose ALL correct statements:
1. Mutation refers to a permanent change in DNA sequence
2. Epigenetic modification refers to a permanent change in RNA sequence
3. The chances of mutations are far lower than epigenetic modifications
4. Epigenetic molecules could be altered by environmental factors or life events
5. Only mutations could cause cancers
6. Mutations are always inheritable while epigenetic modifications may or may not
be
7. Older twins have exactly the same genes and epigenetics.

When in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? view available hint(s)when in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? active transportexocytosis
