Before cellular division, the cell must duplicate its DNA so that daughter cells will contain complete copies of the DNA. Which characteristic of DNA makes it most suitable as a molecule for this role? (BIO.B.1.2.1 2019)

• DNA is located in the nucleus.

• DNA is a large macromolecule.

• DNA is made of repeating sugar-phosphate subunits.

• DNA is made of two strands of complementary nucleotides.

Which statement best explains how organisms accomplish passing on traits to their offspring? (BIO.B.1.2.2 2019)

• Traits are acquired when parents care for their offspring.

• Offspring inherit traits when DNA is replicated during mitosis.

• Traits are inherited by the transfer of genetic material from parent to offspring.

• Offspring acquire traits when cells become specialized for certain functions.

During a cell division cycle, chromosome segments from two homologous chromosomes exchange places. Which result is most likely to occur following this cycle? (BIO.B.2.1.2 2019)

• Genetic material will be lost.

• The number of chromosomes will increase.

• The total number of genes in the cell will decrease.

Which statement best describes how organisms use DNA and amino acids to synthesize a protein? (BIO.B.2.2.1 2019)

• DNA is transcribed into mRNA, which is translated by the ribosome to produce an amino acid chain.

• DNA is translated into mRNA, which is transcribed by the ribosome to produce an amino acid chain.

• Amino acids are transcribed into mRNA, which is translated in the nucleus to produce a molecule of DNA.

• Amino acids are translated into mRNA, which is transcribed in the nucleus to produce a molecule of DNA.

• predation by the top-level organisms

• energy loss between each level of organisms

• chemical energy being decomposed at each level of organisms
