Answer:
D. <em>Because</em><em> </em><em>it</em><em> </em><em>suggests</em><em> </em><em>that</em><em> </em><em>more</em><em> </em><em>antibiotics</em><em> </em><em>are</em><em> </em><em>waiting</em><em> </em><em>to</em><em> </em><em>be</em><em> </em><em>discovered</em>
The statement 'Skin cells and epithelial cells each make a different set of proteins, which determines each cell type's structure and function.' is correct. It is known as differentiation.
<h3>What is differentiation?</h3>
Differentiation refers to the cellular phenomenon for which different genes are expressed in specific cell types.
Differentiation leads to the formation of different cell types that have specific functions/roles.
Differentiation depends on gene expression pattern that influences the type and amount of proteins in a given cell.

Answer:
The division of eukaryotic cell is done through various phase known as cell cycle.
Explanation:
The two basic phases of cell cycle is Interphase and Mitosis, that can be further divided into:
1) G2 Phase; G2 checkpoint ( Interphase stage)
2) Prometaphase (Mitotic Phase)
3) Anaphase (Mitotic Phase)
4) Telophase (Mitotic Phase)
5) cytokinesis (Mitotic Phase)
6) G1 Phase; G1 checkpoint ( Interphase stage)
After G1 phase there would be again S phase in which DNA replication occur.
Cyclins
are the chemicals that regulate the cell cycle. Cyclins work by regulating the timing
of the cell cycle in eukaryotic cell. Cyclins activates cyclin dependent
kinases (CDKs) (an enzyme that works by adding <span>negatively charged phosphate groups to other
molecules in a process called phosphorylation) by binding to it to form a cyclin-Cdk
complex. This complex then functions by acting as a signal to the cell to move
to the next cell cycle phase. At the end of the event, the cyclin is degraded, Cdk
is deactivated, therefore signaling exit from a specific phase.</span>
