Is it true that if you cut a worm in half, the bottom side grows a new head?! If it is, how?!?

Answer 1

No, if you cut one worm in half you either get one dead worm cut in half or you get one worm missing a tail that will regrow depending on where it is cut.

"8. Contrary to popular belief, worms cannot reproduce by being cut into small pieces. However, they do have amazing healing powers. If you cut a worm in half, both sides will continue wiggling. The portion with the head may grow a new tail if the cut is after the segments that contain vital organs. The tail portion will continue to wiggle until the nerve cells die. The tail end will not grow a new head."

"If you cut a worm in half will you get two worms? NO you will not. The head may grow a new tail, depending on where it has been cut."

"It is not true that when you cut a worm in half, each half regenerates. Worms can grow new tails, but not new heads. If you cut the clitellum (the fat ring around the worm that contains many vital organs) in half, you will most certainly kill the worm"

"If you cut the worm in half, you'll get one live worm after the head end grows
back, but the stress of being chopped in two may kill both ends. I'm guessing that being split in half is hard on the poor thing."

Answer 2

you're thinking of the flat malicious software or Planaria. an incredibly trouble-free organism with some very unique qualties. not in hassle-free terms do heads strengthen decrease back; in case you split their head lengthwise it is going to grow to be 2 guy or woman heads. An sure, they do keep in mind. in one test biologist could activate a mild and then 3 seconds later set off a mushy electric ask your self in the malicious software. The malicious software could "shrink back" or cringe. After a time they cut back the worms in a million/2 and the hot head grew. They tried the comparable test yet without the electrical powered ask your self. 3 seconds after turning on the sunshine the hot worms could "shrink back" or cringe. As grotesque as this could sound. The biologists took the test a step greater effective. They did the sunshine on, 3 seconds and then a mushy electric ask your self. Then they floor the worms up and fed them to different flat worms. They then did the comparable test without the electrical powered ask your self; specific adequate the hot worms could "shrink back" or cringe. The planaria is amazingly a maximum suitable animal.
