What is considered research within the scientific method? A suggested explanation of an event, which can be tested and proven later Analyzing data and its validity Combining data from past experiments and using it to investigate a particular topic in consideration Using tools and technology to obtain data for comparison and further investigation None 3. What is the name of the ability of a living thing to maintain constant internal body conditions, despite changes in external conditions? Metabolism Evolution Adaptation Homeostasis None 4. Which of the following microtubules can be used to move the cell? Centrosomes Centrioles Filaments Flagella None 5. How are plant cells different from animal cells? Plant cells contain mitochondria; Animal cells contain chloroplasts Plant cells have a nucleoid region; Animal cells have a defined nucleus Plant cells have membrane-bound organelles; Animal cells do not have membrane-bound organelles Plant cells have a cell wall; Animal cells do not have a cell wall None 6. Choose the correct complementary bases for the DNA strand shown below. T C A G G A CTGAAG AGTCCT TCAGGA GACTTC None 7. In humans, the trait for brown eyes is dominant (B) and blue eyes is recessive (b). Which alleles would be present in the gametes of a human if that human is heterozygous for eye color? Each gamete would include both the dominant and recessive alleles for eye color regardless of the parent's traits. Half of the gametes would contain only the dominant allele while the other half would contain only the recessive allele. Each gamete would include both the dominant and recessive alleles for eye color because the parent is heterozygous, for that trait. Only B would be present because it is the dominant allele. None 8. Which of the following is not true about water? Hydrogen bonding results in water having strong cohesive and adhesive properties. When water freezes, it forms a lattice crystal, causing ice to float. The polarity of water’s bonds allows for covalent bonding between molecules. Large bodies of water stabilize climates due to water’s high specific heat. None 9. Which of the following statements about water is incorrect? Water’s high specific heat allows it to resist temperature shifts. The polarity of water allows it to act as a versatile solvent. The polarity of water allows for covalent bonding between molecules. Water’s cohesive and adhesive properties allow water molecules to bond to other molecules and stick to substances. None 10. Which of the following statements about endoplasmic reticulum is true? The endoplasmic reticulum is attached to the cell membrane. The smooth endoplasmic reticulum is responsible for storing calcium ions. The smooth endoplasmic reticulum is covered in ribosomes. The smooth endoplasmic reticulum is responsible for the assembly of proteins. None 11. Although animal cells lack cell walls, they do have an elaborate system of glycoproteins that provide support to the outside of the cell called the: cytosol extracellular matrix endomembrane system cytoskeleton None 12. What are the two categories of fatty acids? Trans fat and unsaturated fat Saturated and unsaturated fat Steroids and enzymes Phospholipids and polyunsaturated fats None 13. The two types of cells are: animal and plant eukaryotic and prokaryotic animal and eukaryotic eukaryotic and plant None 14. Grocery stores sometimes spray water on their produce to keep the vegetables looking fresh. The cells in these vegetables can be described as: lysed turgid flaccid plasmolyzed None 15. What characteristic of water allows for intermolecular hydrogen bonding? Water’s solvent properties Water’s adhesive properties Water’s cohesive properties Water’s polar nature None 16. Which of the following could cause errors in a scientific experiment? Repeated experimental trials Using double-blind studies Small sample size and limited experimental trials Including all data and using placebos None 17. State the correct order of a scientific process. Theory, observation, evaluation, conclusion Evaluation, theory, experiment, observation, conclusion Hypothesis, experiment, observation, conclusion Observation, hypothesis, experiment, evaluation, conclusion None 18. The entire biochemical reactions taking place in a cell are referred to as __________. Adaptation Homeostasis Response to stimuli Metabolism None 19. Intense workouts can cause sweating in humans. Which of the following characteristics of life does it depict? Maintaining a stable internal environment of the body Cells produce energy for muscle movement Responding to the external stimuli Growth and development None 20. Which of these is NOT true for the polarity of a water molecule? A partial negative charge is on the hydrogen atom. There is no net charge on a water molecule. The polarity is due to the formation of polar covalent bonds. It gives the power of attraction to the water molecule. None 21. Polarity allows water to be a good __________. molecule solution solvent solute None 22. Polymers of which of the following make up proteins? Steroids Nucleic acids Enzymes Amino acids None 23. How are phospholipids important in the function of cells? They are important components of the cytoplasm. They are important components of the cell wall. They are important components of the cytoplasmic skeleton. They are important components of the plasma membrane. None 24. The sum of all chemical reactions that occur in an organism is: Synthesis Metabolism Cytokinesis Cellular respiration None 25. The cytoskeleton of a eukaryotic cell has the following characteristic features except: It has microfilaments made up of proteins. It has fibres that stabilize the cell. It contains microtubules that stimulate cell movement. It is present inside the nucleus. None 26. Which one of the following statements justifies the comparison of plant and animal cells? Plant cells have only one large central vacuole, and animal cells have one or more small vacuoles. Both plant and animal cells have a cell wall. Chloroplast is present in both animal and plant cells. Animal cells have a fixed shape while plant cells have an irregular shape. None 27. Some organisms are able to convert energy without the presence of oxygen continually. They undergo glycolysis to generate energy. What type of process is this? Gluconeogenesis Fermentation Lipolysis Photosynthesis None 28. What is the primary difference between aerobic and anaerobic respiration? Aerobic respiration occurs in the cytoplasm while anaerobic respiration occurs in the mitochondria. Aerobic respiration produces a smaller amount of ATP than anaerobic respiration. Aerobic respiration requires oxygen and anaerobic respiration does not. Aerobic respiration produces lactic acid and anaerobic respiration does not. None 29. Why do plants need to undergo photosynthesis? To reproduce more cells To produce glucose To break down glucose into ATP To remove waste products None 30. The process of photosynthesis is the reverse of which of the following?
