Difference between photoautotrphic and chemoautotrophic nutrition |
|
Answer» The mode of nutrition in which an organism is able to prepare its own food is called autotrophic mode of nutrition. Green plants follow autotrophic mode of nutrition.Autotrophic nutrition is mainly of two types: photoautotrophic and chemoautotrophic nutrition.Autotrophs which synthesise organic matter from inorganic substances using the energy from sunlight through photosynthesis are termed as photoautotrophs. E.g. plants, algae, cyanobacteria, phytoplanktons.Autotrophs which synthesise organic matter from inorganic substances using chemical energy are termed as chemoautotrophs. E.g. nitrifying bacteria like Nitrosomonas, thermophilic bacteria like Thiobacillus. Phototeophic respond in light and chemotrophic respond in the presence of chemical.e.g pollen grain |

The joule\'s law of heating explains the heat produced by a resistor.Elaborate on this law |
|
Answer» Joule’s law of heating states that when a current ‘i \' passes through a conductor of resistance ‘r’ for time ‘t’ then the heat developed in the conductor is equal to the product of the square of the current, the resistance and time.\xa0H = i 2 rtThe reason behind the heat produced is the collision of the free electrons with the lattice ions or atoms while accelerating in presence of the external electric field.we know thatvolt= work done/ total charge or v = w/qfrom this we get w= vqwe know that current i = q / tso q = itputting this in prev equationwe get w = vitfrom ohms law v = irputting it in prev eq we getw = irit = i2rt joule as work is stored as heat soH = I2RT Joules Hi |

Give reasonBile does not contain any enzyme yet it is important for digestion why? |
| Answer» Bile is a digestive juice secreted by the liver. Although it does not contain any digestive enzymes, it plays an important role in the digestion of fats. Bile juice has bile pigments such as bilirubin and biliverdin. These break down large fat globules into smaller globules so that the pancreatic enzymes can easily act on them. This process is known as emulsification of fats. Bile juice also makes the medium alkaline due to presense of NaHCO3 and also activate lipase. | |

State the main feature that categorizes a given pair of organs as homologous or analogous. |
| Answer» Homologous organs are defined as the organs of different animals that are having a similar structure but differ in their functions.Example of homologous organs are the forelimbs of frog, man, and the flippers of the whale. The structure of these animals are the same but the functions are different.The flippers are used for swimming, the forelimbs of frogs are used for jumping and propping, and the forelimbs of man are used for writing, eating, holding things, etc. Having a similar structure shows that all these animals have a common ancestor.Analogous organs are defined as the organs of different animals that are having different structure but perform the same functions.Example of analogous organ is the wings of insect and the wings of the bird. The structure of wings of the bird has bones covered by flesh, skin, and feathers. Whereas the wings of insect is an extension of integument. But in both the cases the wings are used for flying.These organisms would have to adapt to the same ecological niche as other organisms. Hence, they may have evolved similar (analogous) organs. | |

Difference Between solenoid and circular loop. |
| Answer» A solenoid is a long coil containing a large number of close turns of insulated copper wire. Its shape is somewhat like a spiral loop of wire. It may be regarded as a circular coil with very large number of turns. So, we can consider a solenoid up of elementary circular coils.The difference is in their lengths. Solenoid has a longer length compared to its diameter. Also, the distance between its two loops is longer. While a coil has a bigger diameter and the distance between two loops in a coil is shorter compared to its diameter. Thus, we can say that a solenoid looks like a spring at its original or slightly elongated length and a coil as the same compressed spring. | |
