Answer:
A
Explanation:
It's passive transport because it does not require energy, i.e. you don't need to invest ATP to make it happen. Osmosis is the movement of water from area of higher solute concentration to area of lower solute concentration. It happens via channel proteins called aquaporines. Simple diffusion is when gases like O2 or CO2 difuse through the cell membrane. Again, they go from area of higher concentration to area of lower concentration. Facilitated difusion is how large and polar molecules go in and out of the cell. This happens via transmembrane proteins down the concentration gradient (from higher to lower concentration).

elimination of water or some other simple molecule. The combination of two identical molecules is known as self-condensation.
Answer: True
I am pretty sure that it is that
Answer:
Transcription only occur in eukaryotic cells. Transcription and slicing both occur in the nucleus.
Explanation:
Transcription and splicing only occur in eukaryotic cells. Transcription and splicing both occur in the nucleus. Splicing of exons and intron removal is strictly a eukaryotic phenomenon. Prokaryotic genomes are smaller and do not contain introns. Both of these processes occur in the nucleus.
