38pts create 3 questions about the cause-and-effect relationship between the genetic code and gene expression, mechanisms of gene regulation, and/or the role of dna segments that do not code for proteins.

1.what is the difference between genetic code genes and a gene expression?

2. what is the difference of mechanism genes and the DNA segments between them?

3.what is the effect of all four together or their roles to us?!

the fossil record provides evidence of a common ancestor to many species.

here is the answer

water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. weathering is the breaking down or dissolving of rocks and minerals on earths surface. once a rock has been broken down, a process called erosion transports the bits of rock and minerals away.
