Fleas are very small insects. They are all flightless and do not have eyes‚ although two ocelli may be present. Their antennaes are short and their mouthparts are adapted for piercing and sucking. The female flea lays a few eggs daily that total up to 300 to 400 in its lifetime. The eggs are laid usually on animals and most drop off where they spend most of their time. Bedding‚ floor crevices‚ carpeting‚ along baseboards and areas near their favorite sleeping and napping sites are especially likely

vitamins from the greens and vegetables. This happens because many nutrients are fat soluble especially vitamins A‚ D‚ E‚ and K‚ which our bodies need for numerous bodily functions. Essential fatty acids are vitally important for muscle conduction‚ nerve impulses‚ and brain health but our bodies do not make these fatty acids on their own we have to consume them through our diet. The two major essential fatty acids or EFA’s are omega 3 and omega 6. The typical modern diet is far too abundant in omega

Sinoatrial (SA) node in the right atrium and the Atrioventricular (AV) node in the interatrial septum. The electrical signals move through the cardiac conduction system fibres causing the atria and ventricles to contract and relax regularly between 60-100 bpm [1].when those electrical signals are interrupted as a result of a damage in the conduction system‚ the heart rate would become irregular or would either increase resulting in Tachycardia condition or decrease resulting in Bradycardia [2] as

Internal Structure of the Stem The internal structure of the stem is usually more complex than the other plant organs for it performs and provides various functions. These functions are: * For mechanical support * For conduction of water * For conduction and storage of manufactured food * For continuous growth of the stem in thickness These functions are centered at the fibro vascular system that is composed of two major tissues‚ the xylem and the phloem.

materials‚ as conventional insulators‚ the energy band structures are shown large energy gap‚ as shown as Fig. 1 (a) red and blue bands‚ and Fermi level is falling between conduction and valence bands. At room temperature‚ T is about 300 K‚ the gap is so wide that electrons energy level cannot leap from Fermi level to conduction levels. However‚ this situation only happens for the topological insulator’s interior. For surface parts‚ their band structures are much different and behaves as metallic

Behaviourist Thoery/ Thorndike’s Theory of Connectionism/ Trial and Error Learning/ S-R Bond Theory Trial and Error is a method of learning in which various response are tentatively tried and some discarded until a solution is attained. E.L.Thorndike(1874-1949) was the chief exponent of th theory of connectionism or trial and error. He was an American Psychologist who conducted Stimulus - Response(S-R) theory experiment with the help of animals. Thorndike was the first to study the
