By understanding DNA and gene expression, humans have been able to understand how genetic diseases are caused, therefore they have been able to devise gene therapy and other technologies to treat such disease. Second, the understanding has also allowed humans to devise plants that are resistant to pests and drought hence increasing crop yields.
A negative aspect of this understanding is the issue of bioterrorism. In the wrong hands, this technology can be used against society. The technology can be used to modify organisms to make them deliberately harmful to humans. Second is the issue of bioethics. This technology can be used to enhance humans and result to an ‘arms race’ between human races that can tear down the social fabric.
The injury to Kevin’s right cerebral hemisphere could affect
the strength and movement on the left side of his body, as the right half of
the brain controls the left side and vice versa. Reasoning, attention, perception,
social communication and memory are also controlled by the right side of the
brain and these functions could also be impaired from an injury to his right
cerebral hemisphere.

Energy. A solute can only move against concentration gradients using active transport which requires energy
Carbon ^^ is the answer if I’m not mistakenn
