<h3>What is a dam?</h3>
The dam is a large structure that serves the purpose of holding back water and making its level to rise quite high. Dams could be used for the purpose of electricity generation.

Selective serotonin uptake inhibitors began appearing in the MARKET, one example is LUVOX.
Selective serotonin uptake inhibitors are antidepressant drugs. Their major function is to block the re uptake of serotonin in some parts of the brain. The drugs have fewer sides effects compare to other antidepressants and its administration usually brings about approximately 80% of improvement within four weeks of usage. Other examples of selective serotonin uptake inhibitors are: Paxil, Prozc, Zoloft and Celexa.<span />
The spinal cord carries out two main functions: It connects a large part of the peripheral nervous system to the brain. Information (nerve impulses) reaching the spinal cord through sensory neurons are transmitted up into the brain.
Answer:
The model is in the annex
Explanation:
According to the model presented below, after the transition the RNA is in a state called pre-mRNA where we can see the presence of exons and introns. Introns are not sequences of nitrogenous bases that can participate in the production of proteins and therefore are removed from the RNA molecule through a process called splicing. Once the introns are removed, the mRNA is ready and leaves the nucleus towards the cytoplasm, by a process called exportation. Reaching the cytoplasm, the mRNA in association with the tRNA and the ribosomes will give rise to a polypeptide chain, in a process called translation, where the nitrogenous bases are transformed into amino acids.
The polypeptide chain has a linear sequence of amino acids. This chain will undergo several folds in a process called folding, where it will form a three-dimensional structure, the protein.
