Science Practice Questions Review

Question 1: Universal Blood Donor

• Answer: Blood type O
  • Type O lacks A and B proteins, safe for all recipients
  • Universal donor but can receive only from type O
• Universal Receiver: Blood type AB

Question 2: Low Blood Oxygen Levels

• Answer: Fills the right atrium
  • Blood in right atrium is low in oxygen after circulation
  • Delivers oxygen to tissues and picks up CO2

Question 3: Intracellular Chemical Signal

• Answer: To another part of the same cell
  • "Intracellular" indicates signal stays within a cell

Question 4: Path of Food After Oral Cavity

• Answer: Pharynx
  • Connects oral cavity to esophagus, common pathway for food and air

Question 5: Nutrient Diffusion in Digestive System

• Answer: Small intestine
  • Lined with villi for increased surface area and nutrient absorption

Question 6: Invader in Body

• Answer: Pathogen
  • Invader triggers immune response and antibody production

Question 7: Location of Skeletal Muscle

• Answer: Attached to bone
  • Responsible for voluntary movement, posture, stability

Question 8: Perception of Sweet Smell

• Answer: Sensory nervous system
  • Sensory system transmits information to CNS

Question 9: Nervous System and Startle Response

• Answer: Sympathetic nervous system
  • Responsible for fight-or-flight response: increased heart rate, etc.

Question 10: Tissue and Immune Cells

• Answer: Connective tissue
  • Supports immune system, contains immune cells

Question 11: Description of Homeostasis

• Answer: Relatively constant environment within the body
  • Stability despite changes in external conditions

Question 12: Result of Fertilization

• Answer: Zygote
  • Fertilization creates a zygote, which develops into embryo and fetus

Question 13: Male Reproductive System

• Answer: Penis and epididymis
  • Eliminates incorrect options involving female reproductive organs
