Summary - Movements and locomotion takes place as a result of co-operation between the muscle and skeletal system, hence the study of both is necessary. Skeletal system in humans is formed by bones and cartilages. It helps in protection of delicate visceral organs, mechanical support, mov..

>Cartilage forms the embryonic endoskeleton in most vertebrates. In sharks and rays it forms the adult endoskeleton Bone has a matrix (ossein) rich in calcium phosphate. In mammals it is deposited in the form of concentric rings called lamellae, together forming..

Summary - Plants and animals occupy diverse habitats. It may not be possible to study most of them in their natural habitat. Attempts have been made to preserve the plants and animals in a form suitable for scientific studies. Such attempts have resulted in the establi..

Summary - The circulatory systems circulate nutrients, wastes and metabolic intermediates and heat uniformly through out the body. Advanced animals carry blood as the circulating fluid and a circulatory system with the heart and blood vessels to conduct the blood. In invertebratessuch as ..

Introduction - A tissue is a group of cells having a common origin, similar structure and performing a common function. Tissues are characteristic of advanced multicellular animals, commonly called as eumetazoans. They are true multicellular animals where the body cells aggregat..

Coal, Coke, Charcoal (or wood charcoal), Animal Charcoal (or bone black), Lamp black, Carbon black, Gas carbon and Petroleum coke. Diamonds and graphite are two crystalline allotropes of carbon. Diamond and graphite both are covalent crystals. But, they differ considerably in their prop..

Animal cell Plant cell Usually smaller in size Usually larger in size Cell wall is absent. Cellulose in any form is absent Cell wall made up of cellulose is present Cytoplasm is denser, more granular and occupies most of the space in the cell Cytoplasm..

1. By the respiration of living organisms. 2. By the combustion of carbon present in carbon compounds, such as wood, coal, coke, petroleum oil, vegetable oil, alcohol etc. 3. By the decay of organic matter, like the dead bodies of animals and plants. 4. From chemical industry su..

Although matter circulates, energy cannot be reused indefinitely. Solar energy is converted by the photosynthetic producers (plants) into chemical energy in the form of plant carbohydrates. Herbivores consume the plant carbohydrates and so this chemical energy is transferr..

Nitrogen Cycle - Nitrogen is an essential constituent of animal and plant matter as it forms proteins, which are the building blocks of life. The ultimate source of nitrogen is atmospheric nitrogen but neither plants nor animals are capable of assimilating fr..
