Answer: a. tRNA
Explanation: The transference RNA is a nucleic acid that participates of the protein synthesis. tRNA is a small RNA with folding as a trefoil. The tRNA has a site where aminoacid is loaded and a anticodon site that is complementary to the codon in the mRNA, ensuring the proper aminoacid sequence in the resulting polypeptide.
A good conclusion in a research paper restates the hypothesis so that reader can see the value of argument which either defends or criticizes the hypothesis. If it's a long paper it's a good idea to restate the hypothesis in the conclusion. This reminds the user of the hypothesis and draws the paper together. It also revisits the hypothesis and can provide new insight into the hypothesis. Another reason for restating the hypothesis in the conclusion is to pose questions and open the door for future research.
Explanation:
There are several types of antibodies and antigens, and each antibody is capable of binding only to a specific antigen. ... Antigens are bound to antibodies through weak and noncovalent interactions such as electrostatic interactions, hydrogen bonds, Van der Waals forces, and hydrophobic interactions.
Antibodies attach to a specific antigen and make it easier for the immune cells to destroy the antigen. T lymphocytes attack antigens directly and help control the immune response. They also release chemicals, known as cytokines, which control the entire immune response.
The only exception would be nuclear energy. Heavy elements like Uranium got their stored energy from ancient supernovae, that doesn't come from the sun. And fusing hydrogen is tapping energy that has been around since the Big Bang.
Hope this helped :)
