1. Which of the following can be used to observe closely tiny creatures like ants and plant parts like pollen or flower petals? A. hand lens B. hand span C. kitchen tongs D. toothpicks
Answer (1)
A hand lens, also known as a magnifying glass, is a small device with a convex lens that allows you to see small objects magnified. Why other options are incorrect:Hand span:A hand span is a measurement of the distance between the tip of the thumb and the tip of the little finger when the hand is fully extended, and it has nothing to do with magnifying objects. Kitchen tongs:Kitchen tongs are used to grip and hold objects, especially hot food, and they are not designed for close observation of small items. Toothpicks:Toothpicks are primarily used for cleaning teeth, and while they might be used to gently probe some small objects, they do not offer the magnification needed to closely observe tiny creatures or plant parts.
