radioactivity
Answer the following question given this paragraph: Figure 2.43 Positions and velocities of a metal ball released from rest when air resistance is negligible. Velocity is seen to increase linearly with time while displacement increases with time squared. Acceleration is a constant and is equal to gravitational acceleration. Q: If a ball is released from rest when air resistance is negligible, velocity is seen to increase linearly, while what related property is a constant? Choices: - time - speed - density - acceleration A:
acceleration
Q: Answer the following question given this paragraph: 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. Q: What are the three types of rna involved in protein synthesis? Choices: - messenger, organic and transfer - messenger, transfer, and organic - organic , transfer , and ribosomal - messenger, transfer, and ribosomal A:
A: messenger, transfer, and ribosomal
Question: Answer the following question given this paragraph: Polychaetes live on the ocean floor. They may be sedentary filter feeders, active predators, or scavengers. Active species crawl along the ocean floor in search of food. Q: Where do polychaetes live? Choices: - the tundra - great plains - lakes - ocean floor A:
Answer: ocean floor

Answer the following question given this paragraph: Opaque matter is matter that does not let any light pass through it. Matter may be opaque because it absorbs light, reflects light, or does some combination of both. Q: What is the term for matter that does not let any light pass through? Choices: - dark - mirrored - reflective - opaque A:
**Answer**
opaque

Answer the following question given this paragraph: Chordates include vertebrates and invertebrates that have a notochord. Chordates also have a post-anal tail, dorsal hollow nerve cord, and pharyngeal slits. Vertebrate chordates have a backbone, while invertebrate chordates do not. Invertebrate chordates include tunicates and lancelets; both are primitive marine organisms. Q: What do vertebrate chordates possess that invertebrate chordates do not? Choices: - parasite - Thumb - Milk production - backbone A:
**Answer**
backbone
