Q: Answer the following question given this paragraph: A chemical bond is a force of attraction between atoms or ions. Bonds form when atoms share or transfer valence electrons. Q: What bond is a force of attraction between ions and atoms? Choices: - carbon bond - Ionic bond - radiation bond - chemical bond A:
A: chemical bond

Q: Answer the following question given this paragraph: Q: What basic plant structures generally have large surface areas and high surface-to-volume ratios? Choices: - roots - stems - flowers - leaves A:
A: leaves

Q: Answer the following question given this paragraph: Reverse transcription also occurs with retrotransposons and during telomere synthesis in eukaryotes. Retrotransposons are self-replicating segments of eukaryotic genomes that use reverse transcriptase to move from one position in the genome to another via a RNA intermediate. A telomere is a region of repetitive noncoding nucleotide sequences at each end of a chromosome. These sequences protect the end of the chromosome from deterioration or from fusion with neighboring chromosomes. Each time DNA is replicated, small segments of DNA from the ends of the chromosome is lost. Telomerase is a reverse transcriptase that uses an RNA intermediate to elongate the 3' end of DNA strands in the telomere regions after each replication cycle. Q: What is a region of repetitive noncoding nucleotide sequences at each end of a chromosome? Choices: - diploid - cellular - cytoskeleton - telomere A:
A: telomere

Q: Answer the following question given this paragraph: This model for metallic bonding explains some of the physical properties of metals. Metals conduct electricity and heat very well because of their free-flowing electrons. As electrons enter one end of a piece of metal, an equal number of electrons flow outward from the other end, allowing an electrical current to pass through the material with minimal resistance. Additionally, because the electron "glue" that holds the metal atoms together is very easy to deform and reshape, bulk metals can be easily hammered, bent, and pulled without breaking apart. Q: Free-flowing electrons enable what materials to conduct electricity and heat very well? Choices: - noble gases - alloys - acids - metals A:
A: metals
