Ribosomal RNA<span> (rRNA) associates </span>with<span> a set of </span>proteins<span> to form ribosomes. These complex structures, which physically move along an mRNA </span>molecule<span>, catalyze the assembly of amino acids into </span>protein<span> chains. They also bind tRNAs and various accessory </span>molecules<span> necessary for </span>protein<span> synthesis.</span>
glucose and amino acids are completely reabsorbed in the proximal tubule. Most proteins are too large to be filtered by the glomerulus that’s why they are absent in urine.
Hope this helps:)
This is called 'controlled' or 'prescribed' burning. Usually fires in the environment are regarded as undesirable and dangerous, but fires actually fulfil an important ecological role, and animals and plants had adapted to a certain frequency and intensity of fires. The seeds of some trees or grasses germinate after forest or grass fires, as the more open conditions after a fire allows the seedlings to compete and avoid being shaded and smothered by more established trees. Unfortunately, farming and forestry practices have in many cases resulted in a reduction of fires. A reduction in the frequency of fires also allows the build up of dead wood, and when a wild fire does occur, the amount of available fuel results in very hot, large and damaging fires. Therefore, management of forests and other environments such as prairies often use controlled burns to avoid the buildup of dead organic mass and to replicate the natural fire cycle.
Every substance produces light of different colors on the basis of level of energy that is possessed by the electrons of a substance.
<u>Explanation:</u>
Every substance has its level of energy. Depending upon that energy level the light of different colors id produced. There are electrons present in every substance that is made up of atoms and those atoms consist of electrons.
Whenever an atom is heated, the electrons present get excited and their energy level also increases but when their energy level comes down they emit energy in the form of light. The color of that light depends upon the level of energy of an electron. Each substance emits its color.
