Why is it impportant for scientists to devleop a way to grow tissues that have built in system to supply blood

so that whenever we get hurt or something happens our system can grow back like a scar.Everyday it is rebuilding new cells as well as it is always throwing away cells that don't work anymore

surface mining destroys mountain tops, landscapes, forests and wildlife habitats. on top of that, it leads to soil erosion and destruction of agricultural land. the landscape changes can also disrupt river channels and streams, which leads to flooding. which, can destroy plant life and other animals as well.

explanation:

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
