What chemicals regulate the cell cycle how do they work?
Molodets [167]
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>

On the Galapagos Islands, Darwin observed tortoises with domed and saddle-shaped shells. How did Darwin's observations of these
photoshop1234 [79]

Answer:

The correct answer would be C.  The tortoises provided evidence that different species have adaptations suited to their particular environments.

Darwin observed that how different environment on different island lead to the development of different species as a result of adaptations and natural selection.

For example, tortoise inhabiting well-watered islands which used to have short and cropped vegetation had developed a dome-shaped shell.  

In contrast, the tortoise inhabiting the arid islands had developed saddle-shaped shells. It is because they needed to stretch their necks in order to reach branches of cactus and other vegetation available in the area.  

Consequently, they developed long necks and high peak to the front edges of their shells. It made it possible for them to stretch their heads vertically.
