When a cognitive function relies on one cerebral hemisphere more than the other, this phenomenon is known as lateralization.
This means that each side of the brain specializes in some things and works harder on those things than the other side and some neural functions or cognitive processes are specialized to one side of the brain or the other.
The question is asking for some kind of memory, so let's think what kinds of memory are there?
One way to divide memory is into long-term and short-term, and short-term memory describes a small number of recently perceived items. Short term memory is the correct answer here- and if she does not rehearse those words, they won't be passed to her long-term memory.
Avery and his group used enzymes to degrade DNA, RNA and protein in 3S bacteria. DNA from those cells was then tested to see if it can convert 3R cells into 3S cells. It was observed that 3R cells were converted to 3S cells except when the DNA was destroyed. Thus, DNA was pin-pointed as the transforming agent.
