Question : As per Mendel's law, describe the independent assortment of two separate traits (round and green seeds) with (wrinkled and yellow seeds) along with diagram. |
|
Answer» Solution :According to law of independent assortment the two or more different traits are independently passed to the next generation. In other words the receiving of different tratis by the off-spring generation is independent of CHARACTERS (traits) present the parent generation. This can be proved by taking example of a dihydrid cross. The two pure pea PLANTS have round/green seeds and wrinkled/yellow seeds. In `F_(2)` generation we have round/yellow seeds, round/green seeds, wrinkled/green seeds and wrinkled/yellow seeds. This proves that the characters are passed independently. The diagram is as shown below `{:("PARENTS","Round/Green Seeds",,"Wrinkled/Yellow seeds"),(,"RRGG"," "xx,"rrgg"),("Grametes","RGG",,"rg"),(F_(1)" Generation",," RrGg",),("Gamets",,,):}`  `{:("Phenotypic","Round Green",:,"Round Yellow",:,"Wrinkled Green",:,"Wrinkled Yellow"),("Ratio","9",:,"3",:,"3",:,"1"):}` |

Question : Are the fossils being formed at present time ? |
|
Answer» Solution :Fossil formation. Fossilization of a dead organism or its parts usually begins when it is buried before it has a chance to decay. The organism sinks into a bog or a marsh or to the BOTTOM of a lake, sea or river. In some cases it is buried by wind driven sands. Even after burial decay can occur so that soft body parts decompose, a fact which emphasizes again that the hard parts are the ONES that most commonly persist as fossil. The buried parts that do not decay are preserved and as mud or sand hardens to rock, the fossil BECOMES entombed. Fossilization is a hit or miss effect. Only those organisms become fossilized that HAPPEN to die in a spot where they can be buried by natural process before their carcasses are DESTROYED by scavengers. Thus under such conditions fossils are being formed at the present time. |

Question : Aqueous solutions of sodium chloride, sodium sulphate and calcium chloride are taken in three separate test tubes. Using aqueous barium chloride how do you identify sodium sulphate? |
|
Answer» Solution :When a solution of sodium sulphate is added to a solution of barium chloride a white precipitate of barium sulphate will be formed IMMEDIATELY. This precipitate is insoluble in dil-Hydrochloric acid and also insoluble in water. This type of reaction is called precipitation reaction as the `BaSO_4`precipitate THUS formed is of white COLOUR. `Na_2 SO_4 (aq) + BaCl_2 (aq) to BaSO_4(s) + 2NaCl(aq)` Since, barium sulphate is insoluble in water. So it will precipitate as a SOLID, WHEREAS the sodium chloride will remain in solution. |

Question : Answer question the basis of your understanding of the following paragraph and the related studied concepts : After fertilisation, the zygote divides several times to form an embryo within the ovule. The ovuile develops a tough coat and is gradually converted into a seed. The ovary grows rapidly and ripens to form a fruit. Meanwhile, the petals, sepals, stamens, style and stigma may shrivel and fall off. The seed contains the future plant or embryo which develops into a seedling under appropriate conditions. This process is known as germination. Mention the advantages of seed-formation for the plant. |

Question : Answer question on the basis of your understanding of the following paragraph and the related studied concepts : The creation of germ-cells to participate in sexual reproduction is another specialised function, and we have seen that plants develop special cell and tissue types to create them. Human beings also develop special tissues for this purpose. However, while the body of the individual organism is growing to its adult size, the resources of the body are mainly directed at achieving this growth. While that is happening, the maturation of the reproductive tissue is not likely to be a Thus, as the rate of general body growth begins to slow down, reproductive tissues begin to mature.

Question : Answer question on the basis of your understanding of the following paragraph and the related studied concepts : The chromosomes in the nucleus of a cell contain information for inheritance of features from parents to next generation in the form of DNA (Deoxyribo Nucleic Acid) molecules. The DNA in the cell nucleus is the information source for making proteins. If the information is changed, different proteins will be made. Different proteins will eventually lead to altered body designs. Therefore, a basic event in reproduction is the creation of a DNA copy. Is the copy of DNA that is created an exact replica ? |

Question : Answer question numbers on the basis of your understanding of the following paragraph and the related studied concepts : In tissue culture, new plants are grown by removing tissue or separating cells from the growing tip of a plant. The cells are then placed in an artificial medium where they divide rapidly to form a small group of cells or callus. The callus is transferred to another medium containing hormones for growth and differentiation. The plantlets are then placed in the soil so that they can grow into mature plants. Using tissue culture, many plants can be grown from one parent in disease-free conditions. This technique is commonly used for ornamental plants. Where is this technique used ? |
| Answer» Solution :This technique is useful in MAKING large NUMBER of plants which are DESIRABLE or have been infected in a SHORT span of TIME. | |
