Indicate True (T) and False (F) Statements Below Regarding Cytokinesis

question 2

Short Answer

Indicate true (T) and false (F) statements below regarding cytokinesis in animal cells. Your answer would be a four-letter string composed of letters T and F only, e.g. TFFF.
( ) The force for cytokinesis is generated by kinesin motors on microtubule bundles that form the contractile ring.
( ) As the contractile ring constricts, its thickness increases to keep a constant volume.
( ) The midbody forms from bundles of actin and myosin II.
( ) Local activation of Ran GTPase triggers the assembly and contraction of the contractile ring.

Definitions:

Limestone

A sedimentary rock composed mainly of calcium carbonate, typically formed from the skeletal fragments of marine organisms.

Shales

Fine-grained sedimentary rocks that can split into thin, parallel layers, composed mainly of clay minerals.

Siltstones

Fine-grained sedimentary rocks that consist predominantly of silt particles, smaller than sand grains but larger than clay, often formed in quiet water environments.

Lime Muds

Fine-grained sediments composed largely of calcium carbonate, typically formed in marine environments where organisms such as coral or foraminifera are prevalent.
