Fresh day Yhh, let's solve. 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 \(\) Experimentation \(\) 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. Step 1: Identify the given values. m = 75 g V = 39 cm^3 Step 2: Apply the density formula, = (m)/(V). = 75 g39 cm^3 Step 3: Calculate the density. ≈ 1.923 g cm^-3 Step 4: Round to two decimal places. ≈ 1.92 g cm^-3 A. \(1.92 g cm^-3\) 11. In basic science, the three commonly studied states of matter are solid, liquid, and gas. While other states like plasma exist, they are usually introduced in more advanced studies. A. three states of matter Drop the next question 📸
