what is selective reabsorbtion |
| Answer» Nearly 99\xa0per cent of the filtrate formed after glomerular filtration has to be reabsorbed by the renal tubules. This\xa0process is called reabsorption. Though, this reabsorption takes place selectively allowing substances useful to be reabsorbed excluding those not needed by the body. Hence, it is called selective reabsorption. The tubular epithelial cells in different\xa0segments of nephron perform this either by active or passive mechanisms.\xa0For example, substances like glucose, amino acids, Na+,\xa0etc., in the filtrate\xa0are reabsorbed actively. | |

What are the drawbacks of Mandeleev\'s periodic table? |
| Answer» Drawbacks of Mendeleev’s periodic table:1. Position of hydrogen: Hydrogen is placed in group I. However, it resembles the elements of group I (alkali metals) as well as the elements of group VILA, (halogens). Therefore, the position of hydrogen in the periodic table is not correctly defined.2. Anomalous pairs: In certain pairs of elements, the increasing order of atomic masses was not obeyed. In these cases, Mendeleev placed elements according to similarities in their properties and not in increasing order of their atomic masses. For example, argon (Ar, atomic mass 39.9) is placed before potassium (K, atomic mass 39.1). Similarly, cobalt (Co, atomic mass 58.9) is placed before nickel (Ni, atomic mass 58.6) and tellurium (Te, atomic mass 127.6) is placed before iodine (I, atomic mass 126.9). These positions were not justified.3. Position of isotopes: Isotopes are the atoms of the same element having different atomic masses but same atomic number. Therefore, according to Mendeleev’s classification, these should be placed at different places depending upon their atomic masses. For example, isotopes of hydrogen with atomic masses 1,2 and 3 should be placed at three places. However, isotopes have not been given separate places in the periodic table.4. Some similar elements are separated and dissimilar elements are grouped together: In the Mendeleev’s periodic table, some similar elements were placed in different groups while some dissimilar elementshad been grouped together. For example, copper and mercury resembledin their properties but they had been placed in different groups. At the same time, elements of group IA such as Li, Na and K were grouped with copper (Cu), silver (Ag) and gold (Au), though their properties are quite different.5. Cause of periodicity: Mendeleev did not explain the cause of periodicity among the elements.6. Position of lanthanoids (or lanthanides) and actinoids (or actinides):The fourteen elements following lanthanum (known as lanthanoids, from atomic number 58-71) and the fourteen elements following actinium (known as actinoids, from atomic number 90 – 103) have not been given separate places in Mendeleev’s table.In order to cover more elements, Mendeleev modified his periodic table. | |
| 56. |
What is the advantages of Mandeleev\'s periodic table? |
|
Answer» Mendeleev\'s periodic table had the following advantages:1) He had left spaces in his periodic table for the then undiscovered elements2) he had predicted the properties of the undiscovered elements3) noble gases could be accomodate into the periodic table without disturbing the rest of elements. \xa01. He generalized the study of the elements then known as the study of a mere groups.2. In Mendeleev’s periodic table, he left some blank spaces. These vacant spaces were left for including elements that were not discovered at that time.3. Mendeleev could also predict the properties of these unknown elements, on the basis of the properties of the elements lying adjacent to these vacant spaces.He predicted the presence of three elements. They were named as Eka boron, Eka-aluminium and Eka-silicon. The properties of these three elements were similar to the actual elements discovered later.Eka-boron was similar to Scandium, Eka-aluminium was similar to Gallium and Eka-silicon was similar to Germanium.4. When noble gases were discovered later, they could be accommodated in the periodic table in the form of a separate group without disturbing the positions of the other elements.5. He was able to correct the values of the atomic masses of elements like gold and platinum, he placed these elements going strictly by the similarities in their properties. |

Why is small intestine of herbivores longer than carnivorous |
| Answer» The small intestine is longer in herbivore than in carnivore because herbivores eat only grass which is full of cellulose and the digestion of cellulose takes a long time. Bile is a digestive juice secreted by the liver and stored in the gall bladder. The function of bile is to assist fat digestion and absorption in the gut. The length of small intestine differs in various animals depending on the food that they eat. Herbivores need a longer small intestine to allow cellulose to be digested as taken from green plants. | |

Explain Oersted\'s experiment. |
|
Answer» Thanks for your answer Prateek?✌ Oersted ExperimentIn 1820, Oersted established the relationship between electricity and magnetism. He concluded that a current carrying wire produces a magnetic field around it.Aim:To show that a current carrying wire produces a magnetic field around it.Experiment Setup:A thick insulated copper wire is taken and connected with the battery in such a way that current flows from South to North direction in the wire. A compass needle is placed under the wire.Observations:1. When electric current is passed through the wire from South (S) to North (N) directions and the wire is placed over (O) the compass needle, the compass needle gets deflected towards West (W) direction (SNOW Rule).2. On reversing the direction of current in the wire, the compass needle gets deflected in the opposite direction.3. When current is switched off, then there is no deflection in the compass needle.Conclusion:The deflection of compass needle, whenever there is current in the wire shows that a current carrying wire produces a magnetic field around it.This video demonstrate the Oersted\'s Experiment i.e a current carrying conductor produces a magnetic field around it.Hope it will help you ?✌ Thanks for your answer? ✌ Orested showed in his experiment that current carrying conductor can produce magnetic field around itHe took a wire and a magnetic compass for his experiment. When current does not flow in conductor then there is no deflection in the compassBut he took magnetic compass close to current carrying conductor. He observed that there is deflection in the compass And finally he concluded current carrying conductor have magnetic field around it |

Why do mammals and birds have four chamberd hear? |
| Answer» Birds and mammals are warm-blooded animals and maintain a constant body temperature by cooling themselves when they are in a hotter environment and vice versa. So, for respiration to carry out, more eoxygen is required. So, an efficient system of heart is required to separate the oxygenated and deoxygenated blood to carry out proper functioning of the circulatory system which in turn is linked to respiratory system too. So, the four chambered heart is an efficient design that\xa0allows to send "dirty" blood to the the lungs-and "clean" blood to the rest of the body without having to mix the two. | |

What are the postulates of Sir Newton\'s corpuscular theory? |
|
Answer» Can I get your phone no. Which subject do you like most? Hi Priya ? Postulates of Newton’s corpuscular theory:Every source of light emits large number of tiny particles known as ‘corpuscles’ in a medium surrounding the source. These corpuscles are perfectly elastic, rigid and weightless. The corpuscles travel in a straight line with very high speeds which are different in different media.One gets a sensation of light when the corpuscles fall on the retina. Different colours of light are due to different sizes of corpuscles.\xa0 I want your friendship priya |

a) Explain the glucose breakdown by different pathways B) Draw and label budding in hydrw |
|
Answer» It involves the formation of a new individual from a protrusion called\xa0bud. It is very common in plants, yeasts\xa0and lower-level animals such as\xa0Hydra.In\xa0Hydra,\xa0the cells divide rapidly at a specific site and develop as an outgrowth called\xa0bud. These buds, while attached to the parent body, develop into small individuals. When this individual becomes large enough, it detaches itself from the parent body to exist as an independent individual. \xa0Glucose is broken down into a three carbon molecule called pyruvate in the cell cytoplasm. Pyruvate is further broken down by different ways to provide energy in various organisms. Pyruvate is broken down in different ways in different organisms as shown below:i.In yeast cells, during fermentation, pyruvate is converted into ethanol and carbon dioxide in the absence of oxygen.ii. In mitochondria, breakdown of pyruvate takes place in presence of oxygen to give rise three molecules of carbon dioxide and water.iii. Sometimes, when there is lack of oxygen, especially during vigorous activity, in our muscles, pyruvate is converted into lactic acid.\xa0Concept insight:\xa0Students should know various types of respiration.
