define adaptation |
| Answer» <p>Inbiology,adaptationhas three related meanings. Firstly, it is the dynamic evolutionary process that fitsorganismsto their environment, enhancing theirevolutionary fitness. Secondly, it is a state reached by the population during that process. Thirdly, it is aphenotypicoradaptive trait, with a functional role in each individual organism, that is maintained and has beenevolvedbynatural selection.</p> | |

what is mean by adaptation |
| Answer» <p>The special characteristics that enable plants and animals to be successful in a particular environment are called adaptations. Camouflage, as in a toad's ability to blend in with its surroundings, is a common example of an adaptation. ... Adaptations afford the organism a better chance to survive in its surroundings.</p> | |

in define latitude, longitude,adaptation,habitat,physic |
| Answer» <p>Latitude and longitude are imaginary (unreal) lines drawn on maps to easily locate places on the Earth. Latitude is distance north or south of the equator (an imaginary circle around the Earth halfway between the North Pole and the South Pole) and longitude is distance east or west of the prime meridian (an imaginary line running from north to south through Greenwich, England). Both are measured in terms of the 360 degrees (symbolized by °) of a circle.</p> <p>The special characteristics that enable plants and animals to be successful in a particular environment are calledadaptations. Camouflage, as in a toad's ability to blend in with its surroundings, is a common example of anadaptation.</p> <p>The area or natural environment in which an organism or population normally lives. Ahabitatis made up of physical factors such as soil, moisture, range of temperature, and availability of light as well as biotic factors such as the availability of food and the presence of predators.</p> <p>It means a medicine that purges; cathartic; laxative. </p> | |

t are rocks? Name the types of rocks found on earth. |
| Answer» <p>Rock or stone is a natural substance, a solid aggregate of one or more minerals or mineraloids. For example, granite, a common rock, is a combination of the minerals quartz, feldspar and biotite.</p><p>Types of Rocks</p><p>Rocks are not all the same!</p><p>The three main types, or classes, of rock aresedimentary,metamorphic, andigneousand the differences among them have to do with how they are formed.</p><p>SedimentarySedimentary rocks are formed from particles of sand, shells, pebbles, and other fragments of material. Together, all these particles are called sediment. Gradually, the sediment accumulates in layers and over a long period of time hardens into rock. Generally, sedimentary rock is fairly soft and may break apart or crumble easily. You can often see sand, pebbles, or stones in the rock, and it is usually the only type that contains fossils.</p><p>Examples of this rock type include conglomerate and limestone.</p><p>MetamorphicMetamorphic rocks are formed under the surface of the earth from the metamorphosis (change) that occurs due to intense heat and pressure (squeezing). The rocks that result from these processes often have ribbonlike layers and may have shiny crystals, formed by minerals growing slowly over time, on their surface.</p><p>Examples of this rock type include gneiss and marble.</p><p>IgneousIgneous rocks are formed when magma (molten rock deep within the earth) cools and hardens. Sometimes the magma cools inside the earth, and other times it erupts onto the surface from volcanoes (in this case, it is called lava). When lava cools very quickly, no crystals form and the rock looks shiny and glasslike. Sometimes gas bubbles are trapped in the rock during the cooling process, leaving tiny holes and spaces in the rock.</p><p>Examples of this rock type include basalt and obsidian.</p> | |

How do we hear sound? Explain |
| Answer» <p>the human ear is known to be made up of 3 parts 1-the outer ear 2-the middle ear and the 3-the inner ear.the outer ear is also called as the pinna. it collects the sound vibrations from the air. the collected sound vibrations pass through the auditory canal.at the end of the auditory canal,there is a thin membrane called the ear drum or tympanic membrane.when the sound vibrations reach the ear drum the ear drum startsvibrating the vibrations are amplified several times by three bones 1-hammer 2-anvil 3-stirrup in the middle ear.the middle ear transfers these amplified vibrations to the inner ear . here these vibrations are converted into electrical signals.these signals are sent to the brain via auditory nerves it is the brain that finally interprets them as a sound</p> <p>thanks</p> | |

A projectile is fired vertically upwards. It escapes from theearth, when fired with velocity v. If it is to be fired at 45° tohorizontal, what should be its velocity to enable it toescape from the gravitational pull of the earth |
| Answer» <p>Escape velocity is the minimum velocity required for an object to move from Gravitational influence of a massive body . For example , in case of earth escape velocity , ve : 1/2mve² [ Kinetic energy of body ] = GMm/R [ gravitational potential energy between body and earth ]ve² = 2GM/Rve = √{2GM/R} or, √{2gR} </p><p>Here you can see that escape velocity of earth = √{2gR} , which is independent from angle of projection.So , escape velocity will be same , when a projectile is fired at 45° to the horizontal . </p><p>Hence, answer is v</p> | |
