A scientist shaved a patch of white fur off the back of a Himalayan rabbit and applied an ice pack to the area for 30 minutes. The fur in the shaved area grew in black. The best explanation for why black fur grew in the shaved area is that
circulatory system
impact the energy flow and food supply within an ecosystem
warm and cold temperatures activate different genes for fur color
a constant source of energy and recycle gases and materials

Organisms that compete successfully will survive, reproduce, and pass their traits on to their offspring.
vaccines stimulate the subject’s immune system to react to future exposure to the virus
Identify the gene that codes for the protein and introduce it into plant cells by genetic engineering.
In order to make this possible, which process would scientists most likely use?
