Answer:
Explanation:
The hox gene provides a huge amount of important information about evolution. Hox genes duplication made increased morphological complexity possible triggering the formation of neural crest cells and allowed them to disperse throughout the body, forming a variety of structures. They help lay out the basic body forms of many animals including humans, flies and worms.
So sound travels 1 kilometer in roughly 3 seconds and 1 mile in roughly 5 seconds. When you see the flash of a lightning bolt, you can start counting seconds and then divide to see how far away the lightning struck.
A phosphate group is a functional group that typically has a negative charge at the pH of the cell.
- Phosphate groups contain a negative charge at physiological cell pH.
- DNA nucleotides are composed of a phosphate group, thereby exhibiting a negative charge.
- The phosphate group is also fundamental in Adenosine triphosphate or ATP (the energy coin of the cell).
In conclusion, a phosphate group is a functional group that typically has a negative charge at the pH of the cell.
