Elaborate evolution of heart in vertebrates |
| Answer» Vertebrates have a single heart. It is a hollow, muscular organ composed of cardiac muscle fibres. Two types of chambers in heart are atria and ventricles. The heart of lower vertebrates have additional chambers, namely sinus venosus and conus arteriosus or bulbus arteriosus or truncus arteriosus. During the course of development, in higher vertebrates, the persistent portions viz, auricles and ventricles are retained. However, these get complicated by incorporating several valves inside them and becoming compartmentali sed.In fishes, heart is two chambered (1 auricle and 1 ventricle). Both the accessory chambers, sinus venosus and conus arteriosus are present. The heart pumps out deoxygenated blood which is oxygenated by the gills and sent to the body parts from where deoxygenated blood is carried to the heart. It is called single circulation and heart is called venous heart. Lung fish, amphibians and reptiles have three chambered heart, (2 auricles and 1 ventricle). The left atrium gets oxygenated blood from the gills/lungs/skin/buccopharyngeal cavity and the right atrium receives the deoxygenated blood from other body parts. But both oxygenated and deoxygenated blood get mixed up in single ventricle which pumps out mixed blood. This is called incomplete double circulation.\xa0Crocodiles, birds and mammals have a complete four chambered heart (right and left auricles; right and left ventricles). Oxygenated and deoxygenated blood never get mixed. Right parts of the heart receive deoxygenated blood from all other body parts and send it to lungs for oxygenation whereas left parts of heart receive oxygenated blood from lungs and send it to other body parts. This mode of circulation is termed as complete double circulation which includes systemic and pulmonary circulation. There are no accessory chambers in heart of birds and mammals.\xa0 | |

What is difference between double displacement reaction and neutralization reaction? |
|
Answer» A double displacement reaction, also known as a double replacement reaction or metathesis, is a type of chemical reaction where two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products. Here, you can see the general form of a double displacement reaction:In chemistry, neutralization or neutralisation, is a chemical reaction in which an acid and a base react quantitatively with each other.

Limitation of fission |
| Answer» 1. It is dangerous: This creates a radiation-exposure event that can be dangerous to human and animal health.2. It is explosive.3. It creates harmful waste products. Nuclear fission can create clean-burning energy, but the radioactive waste products can be very harmful to the environment.4. It is not a renewable energy resource. Although nuclear fission creates a clean-type of energy, like fossil fuels, it is not a renewable energy resource with our current technologies.5. It can develop long-term health issues for people exposed. Cancers and other health concerns can develop long after the radiation from a nuclear fission reaction or waste product from energy production occurs.6. It has high start-up costs. | |

How to make a generator |
| Answer» The structure of electric generator is similar to that of an electric motor. In case of an electric generator a rectangular armature is placed within the magnetic field of a permanent magnet. The armature is attached to wire and is positioned in way that it can move around an axle. When the armature moves within the magnetic field an electric current is induced. The direction of induced current changes, when the armature crosses the halfway mark of its rotation. Thus, the direction of current changes once in every rotation. Due to this, the electric generator usually produces alternate current, i.e. AC. To convert an AC generator into a DC generator, a split ring commutator is used. This helps in producing direct current. | |

Monohybrid cross and di hybrid cross |
| Answer» Monohybrid cross: Monohybrid cross is that cross which is made to study the inheritance of a single pair of genes or factors of a character. Through monohybrid cross experiments, Mendel proposed the Laws of Dominance and Law of segregation. For example, Tall stemmed plants are crossed with short stemmed plants. A new ratio of 3:1 is formed in the F2 generation. 75% individuals are dominant and 25% are recessive individuals.Dihybrid cross: It is a cross which involves the study of two pairs of genes or two characters. It is the experimentation of two characteristics with their four contrasting traits. For example, Round and Yellow are the two dominant characters, Wrinkled and Green are two recessive characters. Round yellow seed plants are crossed with wrinkled green seed plants in dihybrid inheritance.This produced new ratio of individuals 9:3:3:1. Through dihybrid inheritance, Mendel proposed a new law, Law of independent assortment. Other than dominant and recessive, new combinations are also found. | |

Why are molecular movements needed for life? |
| Answer» The living organisms are well-organised structures; they can have tissues, tissues have cells, cells have smaller components in them, and so on. Because of the effects of the environment, this organised, ordered nature of living structures is very likely to keep breaking down over time. If order breaks down, the organism will no longer be alive. So living creatures must keep repairing and maintaining their structures. Since all these structures are made up of molecules, they must move. | |

Whats is acid, salt and bases? |
| Answer» Acids: The word ‘Acid’ came from Latin word ‘Acidus or Acere’ which means sour. Sour taste is the most common characteristic of acid. Acid turns blue litmus paper red. There are many substances which contain acid and hence taste sour, such as curd, tamarind, lemon, etc.Base: Base is bitter in taste and feels soapy on touch. A base turns red litmus paper blue. Sodium hydroxide (caustic soda), calcium hydroxide, sodium carbonate (washing soda), lime (Calcium oxide), potassium hydroxide (caustic potash), etc. are examples of base.Salt:\xa0 Salts are the ionic compounds which are produced after the neutralization reaction between acid and base. Salts are electrically neutral. There are number of salts but sodium chloride is the most common among them. Sodium chloride is also known as table salt or common salt. Sodium chloride is used to enhance the taste of food. | |

How respiration process happen? |
| Answer» The primary organs of the respiratory system are the lungs, which function to take in oxygen and expel carbon dioxide as we breathe. The gas exchange process is performed by the lungs and respiratory system. Air, a mix of oxygen and other gases, is inhaled. In the throat, the trachea, or windpipe, filters the air. The trachea branches into two bronchi, tubes that lead to the lungs. Once in the lungs, oxygen is moved into the bloodstream. Blood carries the oxygen through the body to where it is needed. Red blood cells collect carbon dioxide from the body’s cells and transports it back to the lungs. An exchange of oxygen and carbon dioxide takes place in the alveoli, small structures within the lungs. The carbon dioxide, a waste gas, is exhaled and the cycle begins again with the next breath. The diaphragm is a dome-shaped muscle below the lungs that controls breathing. The diaphragm flattens out and pulls forward, drawing air into the lungs for inhalation. During exhalation the diaphragm expands to force air out of the lungs. Adults normally take 12 to 20 breaths per minute. Strenuous exercise drives the breath rate up to an average of 45 breaths per minute. | |
