conduction of heat animation of heat animation

The speed of conduction, as mentioned earlier, is faster in myelinated fibres. It can reach up to 120m/s in these fibres. However, the presence of the sheath slows down the conduction to, at times, 0.5m/s. The speed of conduction in the non-myelinated fibres also depen..

Electrons become free to move throughout a crystal when they are excited to a higher energy level within the band. If the highest energy band that is occupied is not fully filled, electrons may be excited from lower energy level to higher energy level by supplying a very small amount of energy beca..

ndigenous dairy breeds produce 6-8 litres of milk a day where as foreign exotic breeds produce 60 litres of milk a day. Even the lactation period (period when milk is produced) is longer. To improve the production of milk of our Indian cows, crossbreeding programmes are conducted at..

Breeding - Indigenous dairy breeds produce 6-8 litres of milk a day where as foreign exotic breeds produce 60 litres of milk a day. Even the lactation period (period when milk is produced) is longer. To improve the production of milk of our Indian cows, crossbreeding programmes are conducted..

Introduction - All living creatures need food. The food is consumed so that energy is obtained. The energy is utilised by the body for various purposes like locomotion, conduction of impulses, repair of damaged tissues, building of cell materials, etc. The substance that is used to releas..

An animal trainer conducted some tests on different kinds of cats to study their reaction time (in seconds) to a specific stimulus. Reaction time Number of cats (frequency) 2.3 - 2.6 6 2.7 - 3.0 2 3.1 - 3.4 10 3.5 - 3.8 8 3.9 - 4.2 4 4.3 - 4.6 12 Which of the ogives represents t..

Fossil fuels are non-renewable and the source of their energy is Sun. The energy from Sun is trapped and stored as chemical energy in plants (and then transferred to animals) is ultimately released as heat and light energy by the fossil fuels on burnin..

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 transferred to them. Carnivor..

These are material contained in the bodies of plants, and animals, which can be used as a fuel or act as a source of fuel. Typical examples of Biomass are, wood, animal dung, agricultural waste (such as, baggasse), wild grass and plants etc. Biomass is a conventional source of ..
