Answer:

C.Test for microtubule proteins, because only eukaryotes have microtubules.

Explanation:

Although some bacteria have similar cellular components, microtubules are only found in eukaryotic cells. This is why it is most likely that if it finds the components that form microtubules, the unidentified organism belongs to the group of Eukaryotes.

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).
