Can u explain me Daltons atomic theory |
| Answer» Dalton’s atomic theory can be explained as follows:1) Matter is made up of atoms. Atoms are indivisible and indestructible.2) All atoms of a certain element are identical in mass and properties.3) Compounds are formed by a combination of two or more different kinds of atoms.4) A chemical reaction is a rearrangement of atoms.In short we can say that,Dalton’s atomic theory states that matter consists of indivisible particles called atoms of a given element are all identical and can neither be created nor destroyed. Compounds are formed by combination of atoms in simple ratios to give compound atoms (molecules).\xa0 | |

Describe the problem faced by the weimer republic |
|
Answer» Weimer Republic was Germany government in 1918 to 1933.In Germany war1 and nazism policy is called Weimer Republic The problems faced by the Weimar Republic were:→ Versailles treaty: The Versailles Peace Treaty at the end of the First World War dispossessed Germany of its territories, its resources and its pride as a nation. He also had to pay 6 billion pounds as war compensation. In spite of the harsh terms, the Weimar Republic accepted the humiliating treaty, thereby making it unpopular amongst the German masses.→ Economic Crisis: The German state was financially crippled due to overwhelming war debts which had to be paid in gold. Subsequently god reserves depleted and value of German mark fell. Prices of essential goods rose dramatically.→ Political defects: The Weimar Republic was weak due to inherent constitutional irregularities such as proportional representation and Article 48 (which gave the President the power to impose emergency and rule by decree). The democratic parliamentary system seemed to give the people no solutions or benefits in the times of the severe economic crisis. |

Explain sound and charatics of sound waves and charatics of sound in detail |
|
Answer» Section is wrong sanctions Sound is the form of energy and it\'s wave travel in the form of compression and rearrfection and it\'s character is the section of hearing Sound is a type of energy. Sound travels in the form of wave from one place to another.Production of sound:Sound is produced because of the vibration of any object. In other words, when an object is vibrated it produces sound.Examples:\tSound can be produced by clapping of palms.\tSound can be produced by vibrating a string.\tSound can be produced by beating a table or diaphragm of a drum.\tSound is produced by a flute because of vibration of air column.\tSound is produced by a guitar because of vibration of its string.Thus, an object is needed which could be vibrated to produce sound.Characteristics of sound wave:Following are the main characteristics of sound wave:\tWavelength\tAmplitude\tTime period\tFrequency\tSpeedTo discuss the characteristics of wave, a graphical representation of sound wave is considered.The peak of a wave is called compression or crest. The valley of a wave is called rarefaction or trough. |

What is the kingdom of animalia |
| Answer» The animal kingdom is classified into different phyla.1. Porifera: These animals have pores all over their body. The pores lead into the canal system. Water flows through the canal system and facilitates entry of food and exchange of other materials. The animal is not differentiated into tissues. The body is covered with a hard outer skeleton. These are commonly known as sponges. They are marine animals. Examples: Sycon, spongilla, euplectelea, etc.2. Coelenterata: The body is made up of a coelom (cavity) with a single opening. The body wall is made up of two layers of cells (diploblastic). Some of the species live a solitary life while others live in colonies. Examples: Hydra, Jelly fish, Sea anemone, etc.3. Platyhelminthes: The body is flattened from top to bottom and hence the name platyhelminthes. These are commonly known as flatworms. The body wall is composed of three layers of cells (triploblastic). Because of three layers, it is possible to form some organs as well. But a proper ceolom is absent in platyhelminthes and hence proper organs are absent. They are free-living or parasitic animals. Examples: Planaria, liver fluke, tapeworm, etc.4. Nematohelminthes: The body is bilaterally symmetric and there are three layers in the body wall. Animals are cylindrical in shape. A pseudocoelom is present and hence organs are absent. Examples: Roundworms, pinworms, filarial parasite (Wuchereria), etc.5. Annelida: True body cavity is present in these animals. The body is divided into segments and hence the name annelida. Each segment is lined one after another and contains a set of organs. Examples: Earthworm, leech, etc.6. Arthropoda: Animals have jointed appendages which gives the name arthropoda. Exoskeleton is present which is made of chitin. This is the largest group of animals; in terms of number of species. Circulatory system is open, which means blood flows in the coelomic cavity. Examples: cockroach, housefly, spider, prawn, scorpion, etc.7. Mollusca: The animal has soft body; which is enclosed in a hard shell. The shell is made of calcium carbonate. Circulatory system is open and kidney like organ is present for excretion. The body has well developed muscular feet for locomotion. Examples: Snail, mussels, octopus, etc. | |

A) What do you mean by monoecious plant ?B) Why are bryophytes called amphibians of plant kingdoms ? |
|
Answer» Bryophyta can live on both land and water \tMonoecious is a condition where a single plant produces both male and female flowers which are helpful in fertilisation process. Coconut palm produces both male and female flowers in a single individual.\tAmphibians are those organisms which live on both land and in water. Bryophytes are called amphibians of the plant kingdom because these plants though live in soil but they need water for sexual reproduction. The sperm of bryophyte (antherozoids) are flagellate and need water to swim to the eggs. In other words, as these plants need water for reproduction unlike other plants, they are called as amphibians.\xa0 |
