Why do insects have eyes with thousands of lenses?

Most adult insects, including bees and dragonflies, have two large compound eyes, made up of separate, sometimes thousands, of lenses. They all point in different directions to give the insect a very wide field of vision.

What is constipation?

Constipation occurs when your body has a hard time having a bowel movement, or going poop. When you digest your food, it collects in the last part of the colon, or the end of the large intestine. If the feces doesn’t have lot of fiber or bulk to it, it stays in the colon longer than it normally would.

Water continues to draw out of the feces, making it hard and compact instead of squishy and moveable. The rectum has to push extra hard to get your poop out. Constipation usually resolves itself, but your body can avoid constipation by eating plenty of fresh fruit, vegetables, and bran, and drinking plenty of water each day.
