Comment on What Do Plants Need to Live? by Robin

Kelly, plants make a chemical reaction powered by sunlight. they take in carbon dioxide from air and react it with water from the ground. The reaction changes them to oxygen and hydrocarbons which are the food we eat. We then do the opposite reaction to get our energy ("sunlight") out from the food!

Comment on Why Do We Have Hair? by mckohtz

The article doesn't tell us why we have hair! Only that we don't have as much hair and women have less than men! Reasons I've heard:- Warmth to stop losing to much heat from our heads Sunblock to stop getting sunburnt Friction reduction under arms and between legs Smell enhancement to attract mates b/c there is more surface area for bacteria to grow! Barrier to stop dust getting in our eyes and noses, and sweat getting in our eyes

Hi, I think your image is missing a vital part: the top 1/2 inch which shows the strings continuing from object to object, thereby moving each part.
