What is seed scatter |
| Answer» Dispersion is scattering of seed from one place to another. If seed are not scattered then the seed will not germinate. Dispersion takes place in different ways. Types of dispersion are:\tDispersion by wind\tDispersion by water\tDispersion by Animals\tDispersion by explosionDispersion by wind: Some plants have small and light seed. Such seed is easily carried away by the blowing wind. Seeds of cotton, simal and some grasses are dispersed by wind.Dispersion by water: Seeds of coconuts and nuts are dispersed by water as such seed can easily float on water. After floating in water whenever seed gets favourable condition it germinates.Dispersion by Animals: When animals migrate from one place to other Some seeds have numerous thorns which get attach to the body of animals. Seeds migrate with the animal. Seeds of guava and tomato are dispersed by animals.Dispersion by explosion:When seed gets ripe, it explodes after some event. | |

What does an electric circuit mean |
| Answer» Electric Current: The flow of electric charge is known as electric current. Electric current is carried by moving electrons through a conductor. By convention, electric current flows in opposite direction to the movement of electrons. Electric circuit is a continuous and closed path of electric current. Electric current is denoted by letter ‘I’. Electric current is expressed by the rate of flow of electric charges. Rate of flow means the amount of charge flowing through a particular area in unit time.I = Q/tWhere, I is electric current, Q is net charge and t is time in second. | |

What do you mean by nutrition in animals. |
| Answer» Nutrition is the process of taking food and using it for obtaining energy, growth and repair of the body. Animals depend on other organisms for getting their food.

What is potential difference and resistivity an resistance? |
| Answer» Resistance: Resistance is a property of conductor due to which it resists the flow of electric current through it. Component that is used to resist the flow of electric current in a circuit is called resistor. S.I.\xa0unit\xa0of\xa0resistance\xa0is\xa0ohm.Resistivity : The resistivity of a material is the resistance of a wire of that material of unit length and unit cross-sectional area. The unit for resistivity is the ohm-metre.Potential Difference: The voltage difference between any two points in a circuit is known as Potential Difference and it is this potential difference that makes current flow. | |
