Q: Q: What paired human organs play a vital role in maintaining homeostasis? Read this paragraph and choose the correct option from the provided answers: The kidneys ( Figure below ) are important organs in maintaining homeostasis , the ability of the body to maintain a stable internal environment despite a changing environment. Kidneys perform a number of homeostatic functions. Choices: - lungs - ears - eyes - kidneys A:
A: kidneys

Q: Q: Ribozymes are rna molecules that catalyze what? Read this paragraph and choose the correct option from the provided answers: Ribozymes are RNA molecules that catalyze chemical reactions, such as translation. Ribosomes, which are just made out of rRNA (ribosomal RNA) and protein, have been classified as ribozymes , because the rRNA has enzymatic activity. The rRNA is important for the peptidyl transferase activity that bonds amino acids. Briefly, the ribosomes interact with other RNA molecules to make chains of amino acids called polypeptide chains, due to the peptide bond that forms between individual amino acids. Inside the ribosome, three sites participate in the translation process, the A, P and E sites. Translation will be discussed in detail the Protein Synthesis: Translation (Advanced) concept. Choices: - liquid reactions - hormonal reactions - protein molecules - chemical reactions A:
A: chemical reactions

Q: Q: Crossing charges is one method for obtaining what? Read this paragraph and choose the correct option from the provided answers: Crossing charges. One method for obtaining subscripts in the empirical formula is by crossing charges. When crossing charges, you will sometimes find it necessary to reduce the subscripts to their simplest ratio to write the empirical formula. Consider, for example, the compound formed by Mg2+ and O2. Using the absolute values of the charges on the ions as subscripts gives the formula Mg2O2:. Choices: - notations - superscripts - hybrids - subscripts A:
A: subscripts

Q: Q: Generators usually transform kinetic energy into what kind of energy? Read this paragraph and choose the correct option from the provided answers: Generators may produce either alternating or direct current, but they all change kinetic energy to electrical energy. Choices: - subsequent energy - potential energy - nuclear energy - electrical energy A:
A: electrical energy
