Question 1:

Image: A graduated cylinder filled with liquid up to the 50 mL mark.
Question: What is the volume of the liquid in the graduated cylinder?

Solution:
- The graduated cylinder is marked with measurement lines, and the liquid level is clearly aligned with the 50 mL mark.
- Therefore, the volume of the liquid is 50 mL.

Answer: 50 mL

Question 2:

Image: A bar graph showing the number of different species in four habitats (A, B, C, D).
Question: Which habitat has the highest biodiversity?

Solution:
- Biodiversity refers to the variety of species in a given area.
- From the bar graph:
- Habitat A has the fewest species.
- Habitat B has more species than A but fewer than C.
- Habitat C has the most species.
- Habitat D has fewer species than C but more than B.
- Therefore, Habitat C has the highest biodiversity.

Answer: Habitat C

Question 3:

Image: A microscope with labeled parts.
Question: Identify the part labeled as "Objective Lens."

Solution:
- The objective lens is the lens closest to the specimen being observed under the microscope.
- In the provided image, the part labeled as "Objective Lens" is correctly identified as the lens near the stage where the slide is placed.

Answer: Objective Lens

Question 4:

Image: A pair of goggles and gloves.
Question: What is the purpose of wearing goggles and gloves in a laboratory?

Solution:
- Goggles protect the eyes from chemical splashes, dust, and other hazards.
- Gloves protect the hands from chemicals, sharp objects, and biological contaminants.
- Together, they ensure the safety of the lab worker by minimizing exposure to potential hazards.

Answer: To protect the eyes and hands from chemical splashes, sharp objects, and biological contaminants.

Question 5:

Image: A pie chart showing the distribution of energy transfer in an ecosystem.
Question: What percentage of the total energy is transferred to the tertiary consumers?

Solution:
- The pie chart shows the distribution of energy among different trophic levels.
- The section labeled for tertiary consumers represents approximately 5% of the total pie chart.
- Therefore, the percentage of energy transferred to tertiary consumers is 5%.

Answer: 5%

Question 6:

Image: A food web diagram with arrows indicating energy flow between organisms.
Question: Identify the primary producer in the food web.

Solution:
- In a food web, the primary producer is the organism that converts sunlight into chemical energy through photosynthesis.
- Primary producers are typically plants or algae.
- In the provided food web, the organism at the base of the energy flow (with arrows pointing outward) is the primary producer.
- Based on the diagram, the primary producer is likely labeled as "Plants" or a similar term.

Answer: Plants (or the organism at the base of the food web)
