When true multicellularity evolved, what two specific mechanisms must have evolved to support it? (choose

The correct answer will be-

1. Autonomous cell specification

2. Cell determination

Explanation:

The multi-cellular organisms have evolved from the unicellular organisms by evolving the two related mechanisms involved in the formation of multi-cellular mechanisms which are- cell determination and specification.

Cell determination is the ability of the cell to determine its fate depending on the chemical detected by the cell in a different region of the embryo. The chemical activates a series of events in cell-like activates a set of genes and intra and intercellular communication.

The Autonomous cell specification is the ability of a cell in which the cell is able to differentiate to carry out a specialized function without receiving any external signals.

Thus, Autonomous cell specification and Cell determination is the correct answer.

clumped distribution, because you'de have all of the population gathered in a relatively small are.

it's the most common because it provides protection and a mate for reproduction

example: humans, seeweed, cattles, etc.
