Answer:
The course of basic first-aid will be helpful for me because it prepares me for any kind of medical emergency, I could save lifes with knowing the correct technique.
Explanation:
Every medical emergency in which someone is in real death danger can involves that the patient´s heart stops and he/she stops breathing. On a basic first-aid course the experts teach us what to do in case that happens, in basic words, to keep the person alive until the ambulance arrives to take the person to a hospital.
First aid involves knowing how to cure a simple burnt to having the heart re-animated by using the needed equipment. They teach us how to to a proper CPR in case someone needs it and-more important- how to know when someone needs it.
Also, they prepar us for several emergencies, like choking with food, an allergy episode (how to use the anti-histamine shot), to keep a fracture well until the specialists arrive.
All this information will be helpful for me as a certified trainer because I will be prepared for any situation and most of all, I will be calm.
Answer:
In the mRNA sequence AUGGUGCAUGUC the maximum number of amino acids that can be encoded is 4 (option A).
Explanation:
Messenger RNA (mRNA) has a sequence of nitrogenous bases produced by the transcription of a DNA strand. This sequence of bases is organized in triplets or codons —made up of 3 nitrogenous bases— that can encode an amino acid, or mark the beginning or end —STOP codon—of protein synthesis.
From the sequence:
AUGGUGCAUGUC
Four codons are obtained, each of which encodes a different amino acid:
<em>Codons: AUG-GUG-CAU-GUC</em>
<em>Amino acids: Met - Val - His - Val</em>
<em>Methionine Valine Histidina and Valine are the four amino acids encoded by the 12 nucleotide sequence of the mRNA.</em>

If the vibrations have a low frequency, the sound is heard as a __low-pitched sound_____. If the vibrations have a high frequency, then the sound is heard as a __high-pitched sound_____.
Explanation:
High pitched sound is of higher frequency because they make the air molecules vibrate much faster than low-pitched sound. Due to their high frequency, their wavelength is shorter (Remember wavelength and frequency are inversely proportional). Vice versa is true to the low-pitched sound. They vibrate air molecules slower than high-pitched sound. Their wavelength is longer and frequency smaller.

Explanation:
Sickle cell anemia is a disease that is caused by the sickle shape of the oxygen carrier molecule called hemoglobin in the blood. The hemoglobin since is a protein, therefore, is composed of the amino acids and it is the 3 D arrangement of these amino acids which provides proteins its function.
The amino acids are coded by the DNA present in the molecule therefore the shape is the result of the DNA. The mutation in the DNA causes the substitution of the glutamic acid to valine at 6th position.
The glutamic acid contains -COOH group in its R side chain which becomes C00- as a result of which the amino acid is negative and acidic in nature. This negative charge allows the formation of bonds with positive change which stabilizes the structure of the protein.
Valine is a neutral and non-polar amino acid therefore will not form any bond with the proteins and thus a stable structure is not formed. This difference in the side chain in the amino acids is the region the hemoglobin structure is changed.
