In all cells, the ribosome produces proteins from amino acids and all three forms of RNA (mRNA, rRNA, and tRNA) in a process called translation.
All RNA comes from transcription that occurs in a eukaryotic cell's nucleus or in a prokaroyte's cytoplasm. Therefore, a eukaroyte's ribosomes often cover the rough endoplasmic reticulum (ER) that often surrounds the nucleus, so it's convenient for those ribosomes to translate the RNA into proteins soon after the RNA leaves the nucleus from transcription.
transpiration is the loss of water conducted by plant through the stomata. the evaporation of water from the leaves results in a suction force which pulls the water up the xylem vessels and out through the stomata. this suction force due to transpiration is the main factor in lifting water and dissolved mineral salts up the plant from the roots to the leaves. respiration on the other hand is a process wereby plants obtain energy by the oxidation of food substances, glucose in other words. this energy is thus utilized for cellular activities and in various chemical reactions going on inside the plant. breathing, a part of respiration, is completely different from transpiration as it involves gaseous exchange from the atmospheric air.
Neutral selection is the changes in a gene pool of a species that are a result of random neutral occurrences that do not give any advantage to that species. Neutral selection does not depend upon adaptation, fitness, or natural selection. If you are referring to the 'Nearly Neutral' theory of natural selection, then read on. If this is a typo for 'Natural Selection', skim down to the next paragraph. The 'Nearly Neutral' theory of evolution states that for a change to come about in the population as a whole, the new characteristic must be better than or equally good as the old characteristic for the change to occur. If, for example, a population of dog has brown eyes, and a new, mutant, blue-eyed dog arrives, then this is not going to be a worse characteristic than brown eyes. This means that the concentration of the blue-eyes in the population can go on a 'random walk' and may become the norm. Natural selection is the main idea behind evolution. Basically, it is based on several observations: 1 - Some members of the species are different from other members of the species 2 - Parents look like their children 3 - Some characteristics will help survival With these in mind, it is clear that those who are better equipped will tend to survive more and pass on their characteristics to their children. That's Natural Selection.
