Sugar in RNA is called Ribose similar to the sugar in DNA which is Deoxyribose
Cilia would be a correct answer.
They do not influence the salinity level in their environment, they maintain the salinity in their body. If they don't, osmosis will cause their cells to shrink due to the fact that the salinity in the cell is lower than outside the cell. This will make water leave the cells. So they need to get rid of excess salt all the time. Freshwater fish need to retain the salt in their bodies, otherwise the opposite will happen. Salinity level in the cell is higher than outside the cell and this causes influx of water which will make the cell build up turgor pressure. Ultimately they will explode. So fishes in both environments adapted to deal with osmosis.
My best guess would be "asexual" (press "thanks" if im right to let me know)
It is very rare for people to distinguish which is which, There is currently no way to distinguish, in the absence of independent evidence, whether a particular memory is true or false. Even memories which are detailed and vivid and held with 100 percent conviction can be completely false. *I got this info from a website*
