Mutations. Definition. A Mutation occurs when a DNA gene is damaged or changed in such a way as to alter the genetic message carried by that gene. A Mutagen is an agent of substance that can bring about a permanent alteration to the physical composition of a DNA gene such that the genetic message is changed.
Answer;
Decision making and emotion; memory and visual processing
Explanation;
Cingulate Cortex is a subcortical structure above the corpus callosum. its anterior (Forward) segment participates in decision making and emotion, and its posterior (rear) segment participates in memory and visual processing.
-The forward 2/3 of this structure, the ACC: anterior cingulate cortex- participates along with the hypothalamus in the control of the autonomic nervous system (also roles in decision making, emotion, anticipation of reward, and empathy)
The rear third, PCC: Posterior cingulate cortex participates in memory and visual processing.
Answer;
b. Their ability to pass on genetic information.
Explanation;
-Protobionts are systems that are considered to have possibly been the precursors to prokaryotic cells. A protobiont is an aggregate of abiotically produced organic molecules surrounded by a membrane or a membrane-like structure.
-They exhibit some of the properties associated with life, including simple reproduction, metabolism and excitability, as well as the maintenance of an internal chemical environment different from that of their surroundings.
