Ques: Q: What are the three types of rna involved in protein synthesis? Read this paragraph and choose the correct option from the provided answers: There are three types of RNA involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribisomal RNA (rRNA). All three of these nucleic acids work together to produce a protein. The mRNA takes the genetic instructions from the nucleus to the cytoplasm, where the ribosomes are located. Ribosomes are the organelles where the proteins are made. The ribosomes themselves are made out of rRNA and other proteins. The mRNA binds to the ribosome, bringing the genetic instructions to order the amino acids to the site of protein synthesis. Finally, the tRNA brings the correct amino acid to the ribosome ( Figure below and Figure below ). In mRNA, the four nucleotides (A, C, G, and U) are arranged into codons of three bases each. Each codon encodes for a specific amino acid, except for the stop codons , which terminate protein synthesis. tRNA, which has a specific "3-leaf clover structure," contains a three base region called the anticodon , which can base pair to the corresponding three-base codon region on mRNA. More will be discussed on these processes in the Protein Synthesis: The Genetic Code (Advanced) and Protein Synthesis: Translation (Advanced) concepts. Choices: - messenger, organic and transfer - messenger, transfer, and organic - organic , transfer , and ribosomal - messenger, transfer, and ribosomal A:
Ans: messenger, transfer, and ribosomal

Ques: Q: What does an ammeter measure the flow of? Read this paragraph and choose the correct option from the provided answers: When a contractor builds a new home, she uses a set of plans called blueprints that show her how to build the house. The blueprints include circuit diagrams. The diagrams show how the wiring and other electrical components are to be installed in order to supply current to appliances, lights, and other electric devices. You can see an example of a very simple circuit in the Figure below . Different parts of the circuit are represented by standard circuit symbols. An ammeter measures the flow of current through the circuit, and a voltmeter measures the voltage. A resistor is any device that converts some of the electricity to other forms of energy. For example, a resistor might be a light bulb or doorbell. Choices: - water under pressure - wind - magnetic fields - current through a circuit A:
Ans:
current through a circuit
