Which of the statement is true about a seed?
-
A seed is not a living thing and it cannot move
-
A seed is a living thing and can grow into seedling
-
A seed died when the fruit is eaten by animals
-
A seed can make its own food
Correct Answer
A. A seed is a living thing and can grow into seedlingExplanation
A seed is a living thing and can grow into a seedling. Seeds are the reproductive structures of plants and contain all the necessary genetic material and nutrients to develop into a new plant. They are capable of germination, where they absorb water and begin to grow roots, shoots, and leaves. This process allows the seed to develop into a seedling and eventually mature into a fully grown plant. Therefore, a seed is indeed a living thing and has the potential to grow into a new plant.Rate this question:

Explain how can we see with the presence of light.
Correct Answer
As light travel in a straight line and it bounces off from the object and reflects into our eyes.Explanation
We can see with the presence of light because light travels in a straight line and when it encounters an object, it bounces off and reflects into our eyes. This reflected light carries information about the object's color, shape, and texture, which is then processed by our brain to form an image. Without light, there would be no source of illumination, and therefore no reflection or perception of objects around us.Rate this question:
