Explanation:

  1. Examples of stimuli and their responses: You are hungry so you eat some food. A rabbit gets scared so it runs away. You are cold so you put on a jacket.
  2. Autotrophs store chemical energy in carbohydrate food molecules they build themselves. Most autotrophs make their "food" through photosynthesis using the energy of the sun. Heterotrophs cannot make their own food, so they must eat or absorb it
  3. If we pull the yarn from the torn pairs of sock, that single yarn only will be pulled out continuously as the fabric gets unraveled and it'll slowly get opened.
  4. A simple device used for spinning cotton and making yarn is called hand spindle. ... The spinning wheel is called Charkha. Spinning of yarn on a large scale is done by using spinning machines in mills or factories. The yarn produced by spinning is then used for making fabric
