When food becomes scarce, hundreds to thousands of independently living single-celled amoebas join to form a multicellular mass that will later reproduce.

Which level of the hierarchy of organization does this mass most
closely represent?

Organ system

Tissue

Organ

Molecule

The correct answer is - tissue.

Explanation:

In an unfavorable condition like scarcity of food, individual unicellular organism amoeba makes a formation a multicellular mass by aggregation of the cells that reproduce when conditions become favorable. These aggregation of cells known as slime molds.

These molds are more similar to the tissue structure in the hierarchy of organization of a multicellular organism. The tissue is the organization level that is similar to this mass as it is also formedby the cells joined together to perform a particular function.

the  different  of  these  two  are  that  they  differently  handle  their  team.

an  expressive  leader  focuses  on  the  task  at  hand  and  make  sures  that  their  goal  is  achieved.  they  accurately  finish  the  task.  an  instrumental  leader  on  the  other  hand  works  on  the  unity  of  the  group,  they  care  more  about  their  employees.  all  the  while  creating  a  good  environment.
