Do invertebrates have limbs for locomotion?​

Terrestrial locomotion has evolved as animals adapted from aquatic to terrestrial environments. Locomotion on land raises different problems than that in water, with reduced friction being replaced by the increased effects of gravity.

Explanation:

Are insects glued to one spot? Think of the mosquito which can land on anything with blood and get what they need. They can also walk around to look for a nice juicy conduit.

Spiders -- same story. They spin their webs and wait to see what hits the webs.

What about the octopus, which has 8 legs to propel him. Almost all insects have ways of moving around.

advantage of using stem cells in medical research:

1.       it provides medical benefits in the fields of therapeutic cloning and regenerative medicine.

2. it provides great potential for discovering treatments and cures to a variety of diseases including parkinson disease, spinal cord injuries, diabetes, alzheimer’s disease and many more.

3. limbs and organ could be grown in lab from stem cells and then used in transplant or treat illness.
