Explain codominance with suitable example. |
|
Answer» Codominance means that neither allele can mask the expression of the other allele. An example in humans would be the ABO blood group, where alleles A and alleles B are both expressed. So if an individual inherits allele A from their mother and allele B from their father, they have blood type AB. |

Double fertilization and triple fusion were discovered by |
|
Answer» Answer: Nawaschin and Guignard •Hofmeister gave organisation of embryo sac and also showed microspore tetrad formation. •Nawaschin while working on Lilium and Fritillaria showed the fusion of one male gamete with the egg (syngamy) and of the other male gamete with polar nuclei (triple fusion). Thus, he discovered double fertilisation and gave the concept of triple fusion. The discovery of double fertilisation by Nawaschin was independently confirmed by Guignard. •Leeuwenhoek was the first to observe microbes under microscope. •Strasburger while working on Monotropa, observed the actual fusion of the male gamete with the female gamete (i.e. egg) and discovered syngamy.

State the meaning of under subscription. |
|
Answer» Under Subscription of Shares When the number of shares applied for, is less than the number of shares offered to the public, the shares are said to be under subscribed. The number of shares for which applications were invited and the number of shares for which applications were received are exactly the same. However, in practice, these two figures will rarely coincide. The number of shares for which applications are received may be more or less than the number of shares for which applications are invited. If the number of shares applied by the public is less, the issue is said to be under-subscribed, if more, then it is said to be over-subscribed; for example if a company invites applications for 10,000 shares and applications are received from public for 8,000 shares the issue is said to be under- subscribed and if they are for more than 10,000 shares, say 12,000 shares then the issue is said to be over-subscribed. In the case of under-subscription, normally all the shares for which the public applies are allotted, as in case of full subscription. |

Explain four factors which lead to an increase in demand for a commodity. |
|
Answer» Factor influencing the demand (i) Price of the commodity itself: When a commodity is selling at a very high price, only rich people are able to buy it. So the demand of that commodity will be less. But when the price is low more and more people will be able to buy it and the demand of the commodity would be more. Thus, the demand of the commodity is greatly influenced by its price. (ii) Prices of other related goods: The demand for a commodity is also influenced by prices of other related goods as substitutes. Tea and coffee are substitutes to each other. A change in the prices of such commodities affects the changes in the consumption of its substitutes. For example, a change in the price of tea will change the consumption of coffee. (iii) Level of income of the consumer: Consumer’s demand is also influenced by the size of his income. This is but natural that with increase in the level of income, there is increase in the demand of goods and services. Increased level of real incomes creates more purchasing power in the country. As the level of income increases, the demand for goods and services also increases. (iv) Tastes and Preferences of the Consumer: Tastes and preferences of the consumer also influence his demand. A taste, fashions, preferences of the consumer keep on changing and is his demand. (v) Population: The change in the population in a country changes the demand. This change in population is in terms of change in the size and composition of population. Increase in the size of population will definitely increase the demand of commodities and services. Again increase in the size of population also affects the composition of population. By consumption of population is meant the distribution of population in terms of the age-group, sex- ratio, and skilled or unskilled population. In a country where the majority of population is composed of minors, naturally demand for such goods will be more which interest more to minor-toys, sports goods, etc. |

Anukalp and Karan are partners with the capital of \( ₹ 25,000 \) and \( ₹ 15,000 \) respectively. Interest payable on capital is \( 10 \% \) p.a. Find the interest on capital for both the partners when the profits earned by the firms is \( ₹ 2,400 \). |
|
Answer» Interest on capital is distributed from the profit but in the capital sharing ratio (1) Find capital sharing ratio: 25000 : 15000 = 5 : 3 (2) Divide profit in the capital sharing ratio: Profit = 5x + 3x = 8x 2400 = 8x x = 300 Therefore, Anukalp share : Karan share = 1500 : 900 . |

Explain the working of bio gas plant |
|
Answer» Organic input materials such as foodstuff remnants, fats or sludge can be fed into the biogas plant as substrate. Renewable resources such as corn, beets or grass serve as feed both for animals such as cows and pigs as well as for the micro organisms in the biogas plant. Manure and dung are also fed into the biogas plant. In the fermenter, heated to approx. 38-40 °C, the substrate is decomposed by the micro organisms under exclusion of light and oxygen. The final product of this fermentation process is biogas with methane as the main ingredient. But aggressive hydrogen sulphide is also contained in the biogas. A fermenter made of stainless steel has the clear advantage that it withstands the attacks of the hydrogen sulphide and is usable for decades. Furthermore, a stainless steel fermenter provides the opportunity to operation the biogas plant also in the thermophile temperature range (up to 56 °C). Once the substrate has been fermented, it is transported to the fermentation residues end storage tank and can be retrieved from there for further utilisation. The residues can be utilised as high quality fertiliser. The advantage: Biogas manure has a lower viscosity and therefore penetrates into the ground more quickly. Furthermore, the fermentation residue quite often has a higher fertiliser value and is less intense to the olfactory senses. But drying it and subsequently using it as dry fertiliser is also an option. The biogas generated is stored in the roof of the tank and from there it is burned in the combined heat and power plant (CHP) to generate electricity and heat. The electric power is fed directly into the power grid. The heat generated can be utilised to heat building or to dry wood or harvest products. Processing of biogas Gas supply to the national grid or gas filling stations |
