  2. Which system is primarily responsible for hormone production and regulation? A. Nervous system B. Circulatory system C. Endocrine system D. Lymphatic system C. Endocrine system The endocrine system produces hormones that regulate body processes.
  3. Which kingdom includes organisms that are multicellular, autotrophic, and have cell walls? A. Animalia B. Protista

C. Plantae D. Fungi C. Plantae Plantae members are multicellular, photosynthetic, and have cell walls made of cellulose.

  1. Which macromolecule provides the most immediate source of energy? A. Protein B. Lipid C. Nucleic acid D. Carbohydrate D. Carbohydrate Carbohydrates are broken down quickly to release glucose for cellular energy.
  2. What is the primary waste product of cellular respiration? A. Oxygen B. Carbon dioxide C. Nitrogen D. Glucose B. Carbon dioxide Carbon dioxide is a byproduct of breaking down glucose during aerobic respiration.
  1. Which of these best describes a gene? A. A chromosome B. A trait C. A segment of DNA that codes for a protein D. A ribosome C. A segment of DNA that codes for a protein Genes are DNA sequences that encode instructions for building proteins.
  2. The nitrogen bases in DNA are held together by: A. Covalent bonds B. Ionic bonds C. Hydrogen bonds D. Peptide bonds C. Hydrogen bonds Base pairs are connected via hydrogen bonds, allowing easy unzipping for replication.
  3. Which biomolecule contains the most energy per gram? A. Protein B. Carbohydrate C. Lipid D. Nucleic acid C. Lipid Lipids contain more energy due to their long hydrocarbon chains.
  1. What is the role of the Golgi apparatus? A. Energy production B. DNA replication C. Protein modification and transport D. Cell division C. Protein modification and transport The Golgi processes and packages proteins for secretion or delivery.
  2. In genetics, what does homozygous mean? A. Two different alleles B. Two dominant alleles only C. Two identical alleles D. Only one allele present C. Two identical alleles A homozygous genotype has two of the same alleles for a trait.
  3. What happens during transcription? A. DNA is copied to form mRNA B. mRNA is translated into protein C. Ribosomes make DNA D. tRNA binds to DNA A. DNA is copied to form mRNA Transcription is the process of converting DNA into messenger RNA.
