When listing the levels of organization in organisms from least complex to most complex, which level is just below organs in com
coldgirl [10]

Answer:

Tissue

Explanation:

Multicellular organisms are complex and every complex organism consist of building blocks. This is the case in the level of organization in living organisms. All living organisms are made up of CELLS. In multicellular organisms i.e. more than one, the cells that perform a similar role come together to form the TISSUE.

Tissues with similar function together forms the ORGAN. Organs that perform similar functions collectively makes up ORGAN SYSTEM. Based on this, the level of organization moves from the least complex "cells" to most complex "organ systems".

The order is as follows:

Cell-----> Tissue-----> Organ-----> Organ systems

Makovka662 [10]

Answer: A. protein like tubules

B. Microtubules

C. Microfilaments

Explanation:

Cytokinesis in the bacteria is facilitated by the presence of these conserved tubulin-like proteins. Due to the fact that their walls are flexible, constriction of these walls is possible aiding in cytokinesis. Unlike in plant that have rigid cell wall, a cell plate is involved in the formation of a new cell wall between the daughter cells. Network of microtubules determines the position of the cell plate which is mostly like a disc in the middle of the two daughter cells. Cleavage furrow occurs in animal cells which is caused by the action of the contractile ring: a ring of actin microfilament.
