<span>Indeed, "carbo" means carbon, while "hydrate" means water, a combination of hydrogen and oxygen molecules. All carbohydrates, including sugar, therefore contain the same three elements: carbon, hydrogen and oxygen. ... Glucose, for instance, is a single-unit carb with six carbon atoms ...</span><span>

B. A moray eel eats a fish swimming by. Predators are organisms that eat other organisms. If this helps, thank me. If this really helps, thank me and, crown me brainliest answer. Also, rate, and comment. This helps me to improve answering, and helps you to get a better answer.
Answer:
b progesterone
Explanation:
The plug is formed as soon as there is implantation of fertilized eggs. The thickness of the cervical mucus becomes different as hormone levels changes in pregnancy.
The progesterone, encourages the production of thick fluid/ mucus which brings about the formation of a plug. This prevents bacteria from getting into the uterine cavity.
Answer:
Go to the first one and there it is
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>.
