What enzyme is present in cancer cells which scientists believe allows the cancer cells to keep growing indefinitely?

The enzyme present in cancer cells that allows them to keep growing indefinitely is called telomerase. Telomerase helps maintain the length of the telomeres, which are the protective caps on the ends of chromosomes. By preventing telomeres from shortening with each cell division, telomerase enables cancer cells to keep dividing and growing uncontrollably.


Why do humans have two sets of teeth?

1. A child's jaw is smaller and requires smaller teeth. That's why when we are born and we start growing out teeth, those teeth are temporary and fall out later on. 2. People needed their teeth to live. Having two sets of teeth (and periodically growing more teeth, like molars and wisdom teeth) meant that even if the front teeth rotted away, the person would still be able to eat. Dentistry hasn't been around anywhere near as long as humans have.
