Answer:
Duplication of Hox genes made increased morphological complexity possible.
Explanation:
- The hox gene cluster consists of a group of related genes that function to controls the basic body plan of an embryo and also define the head to the tail axis.
- These are mainly responsible for ensuring the correct position of al the structures in the body.
- Since the anterior-posterior axis all the vertebrates are established by these hox genes this points out to the fact that common information is needed amongst all he vertebrates to define the various morphological variations that occurred.
- The hox genes have shown duplication in the course of evolution and they have undergone a four-fold duplication which has led to the generation fo different structures in the various organism and is thus responsible for the increased morphological complexity.
Uncontrolled production of cyclins will most likely result in uncontrolled division of the cell.
CELL DIVISION:
- Cell division is a biological process that every cell undergoes to replicate themselves. It is the process by which cells are multiplied in living organisms.
- According to this question, proteins called cyclins bind to enzymes that send signals for the cell to progress through stages of cell replication. However, at the end of the cycle, the cyclins are degraded to prevent further signaling for the cell to divide.
- In a case whereby there is an uncontrolled production of cyclins, this will most likely result in uncontrolled division of the cell because cyclins stimulate cellular division.

Urethra as Nephrons form Kidney and Urethra isn't a part of Kidney.
Answer:
Adhesion
Explanation:
Technically, you need cohesion(water sticking to itself through attraction of hydrogen bonds) to get adhesion(water sticking to other surfaces through attraction of hydrogen bonds). They are rather intertwined. But for this basic answer, it is adhesion.
