Where is dna found? a. vacuole b. chromosomes c. cell membranes d. golgi body

in eukaryote cells DNA is found in the nucleus of the cell, the form the DNA (e.g. chromosomes vs. chromatin) is in depends on what stage of the cell cycle you are talking about. In cells that have mitochondria, DNA is found there as well. Mitochondrial DNA is distinct from nuclear DNA and doesn't code for the same things. In prokaryotic cells DNA is found in the cytoplasm. Don't forget that other entities may also contain DNA such as viruses.

Although DNA is technically confined to the places outlined above, the reality is cells are dying all the time and spilling their contents including their DNA. As a result DNA is all over us and everything we touch, and the same goes for other organisms.

Bacterial cells DON'T typically have a nucleus. They are called prokaryotic because of that (prokaryotic means "before nucleus" where as eukaryotic means "true nucleus"). Their DNA is typically in the cytoplasm usually as a single circular shaped chromosome. The also sometimes have smaller peices of circular DNA called plasmids that are also in their cytoplasm which they can exchange with each other..

passive transport is a movement of biochemicals and other atomic or molecular substances across cell membranes without need of energy input. unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy.

so, according to what that says, i believe it's hypertonic and hypotonic.

good luck!
