Stem cell technology has been useful in many ways. Which of the following would be the most likely use for stem cells?
Mashcka [7]

Answer:

To regenerate damaged tissue

Explanation:

Stem cells can be pluripotent, totipotent or multipotent depending on where they are sourced. This means that they are capable of differentiating into a wide variety of cells. Stem cells can, therefore, be harvested and induced to differentiate into cells or tissues that are intended to be repaired.

Which of the following does NOT help increase conversion of short-term to long-term memories?
Contact [7]

Answer:

Memory consolidation

Explanation:

Short term memory is stored in the brain for relatively short period of time especially for few minutes. Long term memory is stored in brain for long period ( years or lifetime).

Short term memory can be converted into the long term memory by association, rehearsal and involved with emotional state. Memory consolidation is the process of learning new things and store them in previously stored memories. Hence, memory consolidation does not increase the conversion of short memory to long term memory.

Thus, the correct answer is option (1).
