Diapause and cold hardiness in insects – biochemical aspectsMogili Ramaiah
Diapause is a period of suspended or arrested development during an insect's life cycle. Insect diapause is usually triggered by environmental cues, like changes in daylight, temperature, or food availability.
“State of arrested development in which the arrest is enforced by a physiological mechanism rather than by concurrently unfavorable environmental conditions”.
(Beck, 1962)

Here is an presentation on amphibian metamorphosis which includes the basic information on metamorphosis and the morphological, biochemical and regionally specific changes. there is also a hormonal control that takes place and which is very important. there is also coordination of developmental process that takes place.
scott gilbert 6th edition gives a very nice and detailed information on this topic.
happy studying :)

2. Introduction to the Animal Kingdom The Animal Kingdom is the most diverse in appearance. Some animals are so small that they can live inside other animals. Others are many meters long and live in the sea, they can walk, swim, crawl, burrow , fly, or not move at all. Each major group, or phylum, has its own typical body plan.
3. What is an Animal? Animals, members of the Kingdom Animalia, are multicellular, eukaryotic heterotrophs whose cells lack cell walls.
4. Invertebrates- are animals that do not have a back bone. Vertebrates- are animals with back bones Invertebrates and vertebrates
