Question

ben was training for a cross-country bicycle race. during his practice run, bens tire went flat and he fell off of his bike, cutting both knees. he was worried that he would not be able to compete in the race being held in two weeks, but his father told him not to worry: his knees would be healed by then.
what process is responsible for new tissue growth and the healing of bens knees?
a mitosis
b meiosis
c duplication
d transcription

Explanation:

Mitosis is the cell division process that produces identical diploid somatic cells, which is responsible for tissue growth, repair, and healing of injuries like cuts. Meiosis produces gametes for reproduction, duplication refers to DNA copying (not tissue growth), and transcription is DNA to RNA for protein synthesis, not tissue repair.

Answer:

A. mitosis
