Answer:
Diffusion, osmosis and active transport are three similar chemical methods by which single molecules or very small structures are moved across membranes or relatively short distances, often within or between cells.
Explanation:
The movement of substances in and out of cells is a very important part of biology as without it no cell and so no organism could live very long. Substances can only cross the protective cell membrane by diffusion, osmosis or active transport. Mass flow only works at the organ, tissue and whole organism level.
Answer:
Explanation:Seawalls are structures built of concrete, wood, steel or boulders that run parallel to the beach at the land/water interface. They may also be called bulkheads or revetments. They are designed to protect structures by stopping the natural movement of sand by the waves.
Prokaryotic cells DO NOT have a nucleus, so look for those
The DNA in the Prokaryotic cells is not enclosed within the Nuclear membrane. <span />
Well I believe your taking the FLVS science test? If so the answer I got correct was "Kilogram"
