The correct answer is: E) cleavage furrow formation and cytokinesis
Cytochalasin B (cytos-cell and chalasis-relaxation) is a molecule which inhibit network formation by actin filaments by blocking monomer addition. As a result, itshortens actin filaments. This molecule is involved in cytoplasmic division where it blocks the formation of contractile microfilaments. One of the microfilament’s function includes cytokinesis and formation of cleavage furrow so these functions are affected by cytochalasin B.
Answer:
Active transport
Explanation:
The pumping of sodium ions out of the cell into the environment where there is a lower concentration is achieved through active transport. Active transport is the movement of molecules or ions against a concentration gradient across living cell membranes with the utilization of ATP. Active transport takes place through carries located in the membrane.

Answer:
The mRNA molecule is complementary to its DNA template, which depends on the gene being transcribed.
Explanation:
The process of the formation of RNA from DNA is called transcription.
Messenger RNA (mRNA) is a single-stranded RNA molecule that is complementary to its DNA template as the enzyme, RNA polymerase matches the complementary bases to the original DNA strand and then initiates the process of RNA synthesis. Once the strand gets completed, the process got terminated.
Hence, the correct answer is "The mRNA molecule is complementary to its DNA template, which depends on the gene being transcribed."
