Explanation:
Detailed explanation-1: -The hormone ecdysone is synthesised in the prothoracic glands found in the upper thorax of some invertebrates and is released into haemolymph. It is then transported to cells near the surface of the body and causes the loss of the exoskeleton so that a new exoskeleton can form.
Detailed explanation-2: -1 Which statement explains the significance of mitosis in the development of whole organisms? A Mitosis can be controlled at certain points in development, which will change body plans.
Detailed explanation-3: -Phospholipid bilayers within the chloroplast are impermeable to protons.
Detailed explanation-4: -1. Citrate synthase catalyses the conversion of oxaloacetate into citric acid in the Krebs cycle.
