TRNA reads codons from mRNA and then brings attached amino acids accordingly. Amino acids are connected in long chains called proteins.
Diseases have multiple ways of infiltrating your body. Diseases can be transported through blood, air, and physical touch. Once the disease has infiltrated the body, it can spread through out the body in many ways. One of which is by feeding off of other cells energy and reproducing. The pathogens travel through the blood and irritate cells. The irritation of cells can cause the body to consume more energy, to repair the damage. This causes symptoms like tiredness, regurgitation, and sometimes in extreme cases, death.
Lll. a limited supply of necessary resources. If there isn't enough resources the species will have to learn to adapt to be able to gather the new food supply they need. Such as birds and there beaks, if the insects population went down and that was the main food supply for that type of bird they would have to be able to adapt in order to survive, so evolution occurs. Over time that bird would change to adapt to its new feeding source.
Hope this helps!
