In what ways can scientific knowledge be applied that leads to environmental damage?

1. When an organism transfers pollen grains from the anther of a flower to the stigma of another flower on another plant of the same species, it is described as cross-pollination. This involves two different plants of the same species.

• B. cross-pollination

2. Dicotyledons have two cotyledons, while monocotyledons have one. Mango, avocado, and orange seeds are dicotyledons. Oil palm is a monocotyledon.

• C. Oil palm seed

3. Galvanization is the process of applying a protective zinc coating to iron or steel to prevent rusting. Zinc acts as a sacrificial metal, corroding before the iron.

• C. Galvanization

4. Macronutrients are required in large quantities by plants (e.g., Nitrogen, Phosphorus, Potassium), while micronutrients are needed in smaller amounts. Zinc is a micronutrient.

• D. Zinc

5. Humans have different types of teeth (incisors, canines, premolars, molars), which is called heterodont dentition. Homodont describes animals whose teeth are all the same shape, not a specific type of tooth.

• B. Homodont

6. The use of DDT (a harmful pesticide) to kill fish in rivers is an example of scientific knowledge being applied in a way that causes environmental damage.

• C. Use of DDT to kill fish in rivers

7. The scientific method typically begins with forming a hypothesis, which is then tested through experimentation. The results from experiments contribute to scientific knowledge.

• B. Hypothesis $\to$ Experimentation $\to$ Scientific knowledge

8. A fire symbol (flame pictogram) on a chemical bottle indicates that the substance is flammable, meaning it can easily catch fire.

• D. flammable

9. Fundamental quantities are independent physical quantities. Mass is a fundamental quantity, while force, volume, and weight are derived quantities.

• D. Mass

10. To find the density, divide the mass by the volume.
