  • What is enzyme and characteristics?

    What is enzyme and characteristics?

    Enzymes are biological catalysts that facilitate chemical reactions in living organisms. They are typically proteins, although some RNA molecules also have catalytic activity. Enzymes are essential for life because they speed up the reactions that are necessary for cells to function properly. Without enzymes, many biochemical reactions in the body would occur too slowly to…

  • MCQ on Breathing and Exchange of Gases-2

    MCQ on Breathing and Exchange of Gases-2

    Visiting high mountains may cause altitude sickness in men living in plain areas. Prime cause of this is (a) excess of CO2 in blood (b) decreased efficiency of haemoglobin (c) decreased partial pressure of oxygen (d) decreased proportion of oxygen in air. Increase in body temperature makes oxygen haemoglobin dissociation curve (a) shift to left…

  • Why Earthworms Are a Gardener’s Best Friend

    Why Earthworms Are a Gardener’s Best Friend

    Earthworms are considered a gardener’s best friend for several reasons: Soil aeration: Earthworms burrow through the soil, creating tunnels and air pockets that allow air, water, and nutrients to penetrate the soil more easily. This improves soil aeration, which is important for plant root health. Soil structure: Earthworms also help to improve soil structure by…
