During sexual reproduction, the zygote is formed when a male gamete fuses with a female gamete. How many chromosomes does the zygote cell contain? 4n n 2n 3n None 3. Which of the following lists the phases of mitosis in the correct order? Prophase, Metaphase, Anaphase, Telophase Metaphase, Prophase, Anaphase, Telophase Prophase, Anaphase, Metaphase, Telophase Prophase, Metaphase, Telophase, Anaphase None 4. In his genetic experiments, Mendel used: pea plants basil plants cherry trees apple trees None 5. Which of the following correctly differentiates diploid cells from haploid cells? There are (2n) number of chromosomes in diploid cells and (n) number of chromosomes in haploid cells. The sex cells are diploid cells whereas somatic cells are haploid cells. Diploid cells contain only one set of chromosomes and haploid cells contain two sets of chromosomes. Haploid cells are formed in mitosis whereas diploid cells are formed in meiosis. None 6. Alleles of the same type are called: homozygous dominant heterozygous mutations None 7. Which of the following are produced as a result of photosynthesis? Oxygen and water Water and carbon dioxide Carbon dioxide and glucose Glucose and oxygen None 8. Which of the following best describes the molecular structure of water? Two oxygen atoms ionically bonded to one hydrogen atom Two oxygen atoms covalently bonded to one hydrogen atom Two hydrogen atoms covalently bonded to one oxygen atom Two hydrogen atoms ionically bonded to one oxygen atom None 9. Which organelle is correctly paired with its function? Endoplasmic reticulum – locomotion Nucleus – stores DNA Mitochondria – protein synthesis Peroxisome – cellular respiration None 10. Messenger RNA transfers information: from DNA to proteins from RNA to DNA from DNA to ribosomes from DNA to glucose None 11. A repeatable procedure of gathering data to support or refute a hypothesis is known as drawing a conclusion developing a theory conducting an experiment the scientific method None 12. Which of the following needs to be present in order for a substance to be considered a nucleotide? 5 carbon sugar, nitrogenous base, triphosphate deoxyribose, adenosine, triphosphate ribose, amino acid, phosphate 5 carbon sugar, nitrogenous base, phosphate group None 13. What function do cholesterol molecules serve within the cell membrane? They allow the cell membrane to be selectively permeable by making the bilayer structure more flexible. They allow for carbohydrate chains to extend beyond the cell membrane to communicate with other cells. They stabilize the flexible bilayer structure to prevent breakage. They act as transport highways for molecular movement into and out of the cell. None 14. Many cells uptake food through the cell membrane creating a food vacuole in a process known as photosynthesis cytokinesis osmosis phagocytosis None 15. Which of the following is found in animal cells but not plant cells? cytoskeleton cytoplasm chloroplast centrioles None 16. In the Scientific Method, which of the following is a statement or explanation of certain events or happenings based on limited evidence? Hypothesis Conclusion Experiment Observation None 17. Which of the following best describes why polarity is the most important characteristic of water? The benefits of polarity are hydrogen bonding, a high specific heat value, strong cohesive and adhesive properties, and its versatility as a solvent. The benefits of polarity are hydrogen bonding, a high specific heat value, weak cohesive and adhesive properties, and its versatility as a solvent. The benefits of polarity are covalent bonding, a high specific heat value, strong cohesive and adhesive properties, and its versatility as a solvent. The benefits of polarity are hydrogen bonding, a low specific heat value, strong cohesive and adhesive properties, and its versatility as a solvent. None 18. Cells are made up of components referred to as: nucleic acids amino acids organelles phospholipids None 19. Epistasis can be defined as: interaction between two viruses interaction between two genes interaction between DNA and RNA type of mutation None 20. The process of asexual reproduction when a prokaryotic cell divides to form two identical cells where each has the potential to grow and become an independent cell is called: Budding Binary fission Conjugation Transformation None 21. Which of the following lists the steps of the Scientific Method in the correct order? hypothesis, observation, experiment, conclusion observation, experiment, hypothesis, conclusion theory, hypothesis, experiment, conclusion observation, hypothesis, experiment, conclusion None 22. Photosynthesis is the precursor to which other important cellular process? Sexual reproduction Genetic mutation Cellular respiration Cell division None 23. Which of the following shows the correct pair of the reactants and products of cellular respiration? Reactants: Lactic acid and carbon dioxide; Products: Glucose Reactants: Glucose; Products: Lactic acid and carbon dioxide Reactants: Carbon Dioxide, water, ATP; Products: Oxygen and glucose Reactants: Oxygen and glucose; Products: Carbon dioxide, water, ATP None 24. Which of the following is correct about the difference between sexual and asexual reproduction? In asexual reproduction, there is the involvement of two parents. In sexual reproduction, there is an involvement of one parent only. The process of sexual reproduction takes longer than sexual reproduction. In asexual reproduction, daughter cells are genetically different from parent cells. In sexual reproduction, daughter cells are genetically identical to parent cells. In asexual reproduction, diploid parent cells produce diploid daughter cells. In sexual reproduction, diploid parent cells produce haploid daughter cells that combine to form diploid offspring. None 25. Which of these is present in both prokaryotic and eukaryotic cells? Ribosome Vacuole Endoplasmic reticulum Lysosome None 26. Humans have 46 chromosomes in each somatic cell.
