The correct Answer is:
**Step-by-Step Text Solution:** 1. **Understanding the Question**: The question asks why thousands of years old mummies are still in good condition. This implies that certain biological structures or components within the mummies have resisted decay over time. 2. **Identifying the Options**: The options provided are: - Collagen fibres - White elastin fibres - Yellow elastin fibres - Veins 3. **Analyzing Each Option**: - **Collagen Fibres**: These are structural proteins found in various connective tissues. While they provide strength, they are not as resistant to chemical changes as some other proteins. - **White Elastin Fibres**: This term is misleading as elastin is typically categorized as yellow elastin. White fibres are generally associated with collagen. - **Yellow Elastin Fibres**: These are formed by the protein elastin, which is known for its elasticity and durability. Elastin is highly resistant to chemical changes, making it a strong candidate for preservation. - **Veins**: These are blood vessels that transport blood. They are made of various tissues and are not known for their resistance to decay. 4. **Conclusion**: Based on the analysis, yellow elastin fibres are the most resistant to chemical changes and play a crucial role in the preservation of mummies over thousands of years. Therefore, the correct answer is **yellow elastin fibres**. ---

Carbon -14 used to determine the age of organic material. The procedure is absed on the formation of C^(14) by neutron capture iin the upper atmosphere. ._(7)N^(14)+._(0)n^(1) rarr ._(6)C^(14)+._(1)H^(1) C^(14) is absorbed by living organisms during photosynthesis. The C^(14) content is constant in living organism. Once the plant or animal dies, the uptake of carbon dioxide by it ceases and the level of C^(14) in the dead being falls due to the decay, which C^(14) undergoes. ._(6)C^(14)rarr ._(7)N^(14)+beta^(c-) The half - life period of C^(14) is 5770 year. The decay constant (lambda) can be calculated by using the following formuls : lambda=(0.693)/(t_(1//2)) The comparison of the beta^(c-) activity of the dead matter with that of the carbon still in circulation enables measurement of the period of the isolation of the material from the living cycle. The method, however, ceases to be accurate over periods longer than 30000 years. The proportion of C^(14) to C^(12) in living matter is 1:10^(12) . What should be the age of fossil for meaningful determination of its age ?

A man of mass 50 kg is runing on a plank of mass 150 kg with speed of 8 m//s relative to plank as shows in the figure (both were initially at rest and velocity of man with respect to ground any how remains constant). Plank is placed on smooth horizontal surface. The man, while runing, whistle with frequency f_(o) . A detected (D) placed on plank detects frequency. The man jumps off with same velocity (w.r.t. to groung) from point D and slides on the smooth horizontal surface [Assume coefficient of friction between man and horizontal is zero]. The speed of sound in still medium is 330 m//s . Answer the following questions on the basis of above situations. The frequency of sound detected by detector D, before man jumps of the plank is

743 children from the United States, aged 6 through 11, were tested to see if they were overweight . The data are shown in the table below. In 2014 the total population of children between 6 and 11 years old, inclusive , in the United States was about 74.3 million. If the test results are used to estimate information about children across the country, which of the following is the best estimate of the total number of children between 9 and 11 years old in the United States who were overweight in 2014 ?
