    1. Incorrect, not all the enzyme work inside cells

    For example, if you consider the process of digestion in humans, carbohydrases, proteases, lipids are secreted in digestive juice which work out of the cells in the food molecules.

    2. Incorrect, the bird living in the tree must not be the primary consumer

    This is because it doesn't feed on the tree.

    3. Correct

    Most of the minerals taken by the plant are absorbed in the form of soluble ions, such as sulphates, nitrates, using active transport.

    Moreover, some minerals are absorbed by diffusion of water into the roots.

    4. Incorrect, iron is mainly for the formation of haemoglobin proteins

    5. Correct

    6. Incorrect, veins are never permeable for white blood cells to pass through

    7. Correct

    (Iris radial muscle contracts but iris circular muscle relax)

    9. Correct

    When the eye focus on the distant object, the circular ciliary muscle relaxes and the tension in the suspensory ligaments is reduced, the lens curvature is also reduced and it refracts light less to focus distant object

    10. Incorrect

    The statement is untrue in words. If we consider eating eggs, the proteins coming into our alimentary canal do not cause the formation of antibodies.

    Antibodies are caused to form when other kinds of antigens enter our body by lymphocytes.

    Growth is the non-reversible increase in size and weight of an organism,

    12. Incorrect

    13. Correct

    14. Incorrect

    In muscle contraction, both aerobic and anaerobic respirations(BY FAST SWITCH MUSCLES) are carried out.

    15 Correct

    Sea water contains a large amount of minerals, when drank into our bodies, much more water is excreted through the kidney and can cause dehydration if a large amount of sea water is drunk.
