The risk of developing liver cancer for someone who consumes 4 units of alcohol a day is twice as high as normal (hepatocellular carcinoma and intrahepatic cholangiocarcinoma).
<h3>What does alcohol do to the liver?</h3>
Alters the production of enzymes, changing the rate of metabolism of the alcohol consumed, causing chronic inflammation, alcoholic hepatitis and cirrhosis. Irritates the mucous membranes of the stomach and esophagus, causing esophagitis, gastritis and diarrhea.
With this information, we can conclude that The risk of developing liver cancer for someone who consumes 4 units of alcohol a day is twice as high as normal (hepatocellular carcinoma and intrahepatic cholangiocarcinoma).

Answer:
C. endoplasmic reticulum
Explanation:
I don't have any notes on this but research says C! Hope this helps :)
Answer:
Key molecules that contain carbon include proteins, nucleic acids, carbohydrates and lipids. Carbon is an integral part of many biological processes, including reproduction, photosynthesis and respiration. We often assume that life in other parts of the universe, if we ever find it, will be carbon-based.
Explanation:
Answer: Acceptor stem and anticodon loop.
Explanation:
Transfer RNA (tRNA) is a small RNA nucleic acid involved in protein synthesis (translation). Each tRNA molecule has two important areas:
- A region of trinucleotides, called the anticodon
- A region where a specific amino acid binds.
<u>During translation, the ribosome reads the sequence of the mRNA in groups of three bases to assemble the protein</u>. So, in the mRNA chain there are codons, set of three bases, which determine the amino acid to be added to the peptide chain. <u>The tRNA transfers the amino acid</u> to the ribosomes, and then arranges them along the messenger RNA (mRNA) molecule. <u>Then, the tRNA must have an anticodon that is complementary to the codon.</u> Each type of tRNA is specifically combined with 1 of the 20 amino acids to be incorporated into proteins.
This means, during translation, each time an amino acid is added to the growing chain, <u>a tRNA molecule is formed whose base pairs have a complementary sequence with mRNA molecule</u>, ensuring that the appropriate amino acid is inserted into the protein. So, tRNA is a key link between RNA transcription and the translation of that RNA into protein. On the other hand, aminotransferases are enzymes responsible for attaching amino acids to the 3ʹ‐end of cognate tRNAs.
The acceptor stem is the site of attachment of amino acids to tRNA, and anticodon loop is the site of tRNA that is complementary to the codons found in mRNA (that determine the amino acid that will be added) This means, both parts are important for recognition, <u>because the acceptor stem is where the amino acid is, and the anticodon loop ensures that the appropriate amino acid is inserted into the protein</u>.
