NERVOUS SYSTEM. This chapter contains important concepts related with Control and co-ordination in animals and plants, Tropic movements in plants, Introduction to plant hormones, control and co-ordination in animals, the nervous system, voluntary, involuntary and reflex action, chemical co-ordination, animal hormones. THEORY. HERBIVORES, CARNIVORES AND OMNIVORES The organisms which eat both plant food as well as meat of animals are called omnivores. The best examples of omnivores are human beings, crow, dog, sparrow and ants etc. SLOW AND FAST CHEMICAL REACTIONS 2. Fast chemical reactions. 1. Slow chemical reactions. These are those chemical reactions which take place at very slow rate. These reactions can take days, months or even years to complete. In general the reactions between covalent compounds are slow. For example rusting of iron or fermentation of sugar into ethyl alcohol and carbon dioxide PERIODS IN PERIODIC TABLE The modern periodic table was constructed by the Russian chemist Dmitri Mendeleyev in 1869. The modern periodic table consists of horizontal rows called periods and vertical columns called groups.These are discussed below: Periods in the modern periodic table. A period may be defined as horizontal row in the periodictable.
FRAGMENTATION AND REGENERATION Fragmentation Fragmentation may be defined as the process of breaking up of parent animal into small parts, each of which can grow into a new complete individual. This process of asexual reproduction is found in planaria and hydra. Regeneration Regeneration may be defined as the ability of an organism to grow its lost parts. This method of asexual reproduction is found in protozoa, sponges EFFECTS OF REFRACTION OF LIGHT A coin or stone lying at the bottom of a container filled with water appears to be raised because of refraction of light. A line or a spot of ink on a paper always appears to be raised when viewed through the glass slab due to the refraction of light. Twinkling of stars is due to the refraction of light. Optical illusions such as mirage and EXCRETION IN EARTHWORM In earthworm carbon dioxide and nitrogenous wastes are the main waste materials. The carbon dioxide is excreted out from the body through its moist skin by the process of diffusion.EXCRETION IN AMOEBA
Excretion in Amoeba. Amoeba is a unicellular organism found in fresh water. In amoeba carbon dioxide and ammonia are the main waster materials. These waste materials are excreted out by the process of diffusion through general body surface. In amoeba, contractile vacuoles also play some role in the removal of waste materials. FORMATION OF DIFFERENT TYPES OF IMAGES BY CONVEX LENS Formation of different types of images by convex lens. We will now discuss the formation of different types of images by a convex lens when the object is placed. 1. At infinity. 2. Beyond 2F. 3. At 2F. 4.FUN SCIENCE

The magnetic effect of current was discovered by H.C. Oersted in 1820. He observed that flow of electric current through a conductor produce a magnetic field around it. The magnetic effect of current can be demonstrated by doing following experiment. First of all make a simple electrical circuit by joining a long straight wire with a batterySPORE FORMATION
Spore Formation. Spore formation is a method of asexual reproduction which is found in non flowering plants such as fungi (Rhizopus) and bacteria. In this method of reproduction, the parent plant produces hundreds of tiny spores which can grow into new plants. The spores are the microscopic, tough and resistant bodies which are round in shape RESPIRATION IN PLANTS Respiration in Plants. In order to carry on respiration, plant cells need oxygen and a means of disposing of carbon dioxide just as animal cells do. Unlike animals, plants have no specialized organs for gas exchange (with the few inevitable exceptions!). Each part of the plant such as leaves, stems and roots perform their own respiration. MANUFACTURE OF CEMENT Manufacture of Cement. To manufacture cement first of all limestone is added into the clay in proportion of 3:1 by weight. This mixture of limestone and clay is then dried and crushed to get a fine powder called ‘raw meal’.The raw meal is then added into a rotary kiln through a hopper as shown in figure. PROPERTIES OF ETHANOL Following are the important chemical properties of ethanol. 1. Combustibility. Ethanol can easily burn in air to produce carbon dioxide and water. 2. Reaction with Na Metal. Ethanol Reacts With Sodium Metal To Produce Sodium Ethoxide And Hydrogen Gas. 3. Dehydration of Ethanol. NERVOUS SYSTEM OF INSECT Nervous System of Insect. In an insect, a long nerve cord is present which runs along the whole body. Like hydra, insects also do not have a brain. Instead of brain, many ganglia are present at intervals on the nerve cords. A ganglia is a mass of nerve cells. The largest ganglion is present in head of an insect. HYDROGEN | FUN SCIENCE An atom of hydrogen contains one electron and one proton. It is a unique element because it can lose as well as gain one electron. When an atom of hydrogen loses one electron it acts as metal. On the other hand, when an atom of hydrogen gains one electron, it acts as non-metals. A molecule of hydrogen gas consists of two atoms ofhydrogen (H 2
TYPES OF RESPIRATION Types of Respiration. The process of respiration can take place in the presence as well as absence of oxygen. Hence, respiration is of two types: 1. Aerobic respiration and. 2. Anaerobic respiration.FUN SCIENCE

He observed that flow of electric current through a conductor > produce a magnetic field around it. EXPANSION & CONTRACTION OF AIR :- Air is a mixture of many gases. The molecules of gases present in air have weak inter-molecular forces of attraction . Due to this reason these molecules lie far apart from each other. TYNDALL EFFECT :- A colloid is a heterogeneous mixture. The size of particles of a colloid is too small to be individually seen by naked eyes. They do not settle down when leftundisturbed.
COMBINATION OF RESISTANCES :- When two or more resistances are connected end to end so that same current flows through each resistor they are said to be connected in series.FEATURED TOPICS
