1. How are yarns made from fibres? Give an example.2. Briefly explain any one process to make fabric from yarn.3. The snake does not move in a straight line on the ground. Explain.4. The stem is like a two way street. Explain. |
|
Answer» Explanation: 1. Yarns are made up of thin strands called fibers. The process of making yarn from fibers is called spinning. In this process, a mass of cotton wool are drawn out and twisted. This brings the fibers together to form yarn. 2. The process of making a fabric by INTERLOCKING loops of single yarn with knitting needles or machines, is called knitting. Knitting is done by hand and also on machines. 3. Rectilinear locomotion' which is one AMONG the 5 most common types of locomotion observed in snakes. This movement in a straight line is commonly observed in Boa constrictors or PYTHONS (extremely useful while climbing trees) All snakes are capable of the 5 kinds of locomotion. (I will explain if you are INTERESTED to know) So yes, snakes do move in a straight line but it depends on the type of surface they have to crawl on, their speed and various other external factors. The only REASON why it is not commonly observed in most snakes is because the necessity to move in a straight line is comparatively less. 4. Stem is like a two way street as it conducts water and minerals from the roots to the leaves and transport food prepared by the leaves to the other part of the plant. |
