What characteristics do all eukaryotic cells have in common?

All Eukaryotic Cells Have nucleus, endomembrane system …. etc. read your textbook, it's not a difficult question at all They all hold prisoners? I don't know, I'm just a democrat. Eukaryotic cellscellscells are a sort of telephone greater suitable puzzling than their opposite numbers, prokaryotes. Prokaryotes comprise the simplistic bacteria and archaea, on the comparable …

Some general evolutionary change trends in animals include:?

A. greater surface area to volume ratio, radial symmetry, diffusion to move nutrients in the body. B. radial symmetry, motility, filter feeding. C. lower surface area to volume ratio, radial symmetry, mutualism with photosynthetic organisms. D. larger body size, bilateral symmetry, and an enclosed, fluid-filled body cavity. E. bilateral symmetry, chitinous cell walls, ability to …

How does the nucleus and ribosomes work together to perform functions in the cell?

Try Wikipedia! http://en.wikipedia.org/wiki/Nucleus_%28… It's worthwhile trying to learn it for yourself. The nucleus contains DNA in the form of chromosomes. The DNA gets transcribed into mRNA, which is translated by the ribosomes into proteins. When a certain function is needed in the cell, cellular signals (proteins, hormones, etc) will activate transcription, leading to the production …
