Answer:
An mRNA template is used to create an amino acid chain.
Explanation:
Transcription is the first step in the protein synthesis process. Translation is the second.
Overall, the central dogma of biology is DNA->RNA->protein.
Transcription is that first step, DNA to RNA, and translation is RNA to protein: think of it like nucleic acids can just be transcribed, but nucleic acid to protein is like a whole different language, so it has to be translated. So the correct answer here is that mRNA is used to make amino acid chain (aka protein), which happens only in translation.
The correct answer is: check for correct placement of the NG tube.
An adequately functioning nasogastric (NG) tube shouldprevent nausea and vomiting because stomach contents
are continuously being removed. Using the NG after abdominal surgery is a routine postoperative procedure until gastrointestinal tract start tofunction properly. The patency of the tube should be checked together with the amount and character of gastric drainage.
Answer:
integumentary, muscular, skeletal, nervous, circulatory, lymphatic, respiratory, endocrine, urinary/excretory, reproductive and digestive

Snakes can live up to 9 years. They slither up to 18 mph. Snakes are reptiles that are elongated, limbless, and carnivorous. Another interesting thing about snakes is that they don’t have eyelids. The last fact is that snakes can open there mouths up to 150 degrees so they can swallow there prey.
<span>There are numerous proteins in muscle. The main two are thin actin filaments and thick myosin filaments. Thin filaments form a scaffold that thick filaments crawl up. There are many regulatory proteins such as troponin I, troponin C, and tropomyosin. There are also proteins that stabilize the cells and anchor the filaments to other cellular structures. A prime example of this is dystrophin. This protein is thought to stabilize the cell membrane during contraction and prevent it from breaking. Those who lack completely lack dystrophin have a disorder known as Duchene muscular dystrophy. This disease is characterized by muscle wasting begininng in at a young age and usually results in death by the mid 20s. The sarcomere is the repeating unit of skeletal muscle.
Muscle cells contract by interactions of myosin heads on thick filament with actin monomers on thin filament. The myosin heads bind tightly to actin monomers until ATP binds to the myosin. This causes the release of the myosin head, which subsequently swings foward and associates with an actin monomer further up the thin filament. Hydrolysis and of ATP and the release of ADP and a phosphate allows the mysosin head to pull the thick filament up the thin filament. There are roughly 500 myosin heads on each thick filament and when they repeatedly move up the thin filament, the muscle contracts. There are many regulatory proteins of this contraction. For example, troponin I, troponin C, and tropomyosin form a regulatory switch that blocks myosin heads from binding to actin monomers until a nerve impulse stimulates an influx of calcium. This causes the switch to allow the myosin to bind to the actin and allows the muscle to contract. </span><span>
