Analyze Question 11

Using the Analogous Structures knowledge point, we need to find two structures that perform the same function.

• Human hands are used for grasping and manipulation.
• Penguin flippers are used for swimming (propulsion in water).
• Shark tails are used for swimming (propulsion in water).
• Monkey tails are used for grasping branches (balance and prehensile gripping).

Comparing the functions:

• Penguin flippers and shark tails both serve the function of swimming through water.
• Therefore, penguin flippers and shark tails perform the same function. This matches option C.

Analyze Question 12

Using the Cell Theory knowledge point, we evaluate the statements about all plant and animal cells:

• Option A: "Cells require light for energy." This is incorrect because animal cells and non-photosynthetic plant cells (like root cells) do not require light directly for energy; they use chemical energy (glucose).
• Option B: "Cells are the basic unit of life." This is a fundamental tenet of cell theory and is true for all living organisms, including all plants and animals.
• Option C: "Cells are dependent on other cells." This is incorrect because unicellular organisms exist independently, and even within multicellular organisms, some cells can function autonomously in culture.
• Option D: "Cells can be produced from non-living matter." This is incorrect because cell theory states that all cells arise from pre-existing cells (biogenesis).

Thus, the correct statement is option B.
