Answer:
They release chemical messengers to communicate with cells they may or may not be in direct contact with.
Explanation:
Unicellular organisms such as bacteria or yeast, 'talk' to each other through the release of chemicals. In bacteria, this is known as quorum sensing which allows them to determine the surrounding bacterial population density. In yeast, one of the more popular pathways is known as the mating factor pathway, which allow the organisms to find mates. Whereas, in multicellular organisms (such as humans), this chemical release allows for cell-cell co-ordination which keeps the system functioning correctly.
Answer:
That'll be a "Long term change".
Goodluck with your test! :)
Answer:
Prokayotes may be defined as the organisms that lacks the nucleus and the membrane bound cell organelle. Eukaryotes have the well defined nucleus and contains the membrane bound cell organelle.
The evolutionary advantage that has been noticed in the eukaryotic cells is the compartmentalization of the cell. The cell compartmentalization separates the cell organelle into the specialized functions. This division of labor increases the efficiency of the cell and regulates the evolution of the complex multi cellular organism.
