Given:
Jacky leaves the office at 4:15 PM and she reaches her house at 4:55 PM.
Distance between office and her house = 25 km
To find:
The driving speed of Jacky.
Solution:
The difference between 4:15 PM and 4:55 PM is 40 minutes.
60 minute = 1 hour
1 minute = [tex]\dfrac{1}{60}[/tex] hour
40 minute = [tex]\dfrac{40}{60}[/tex] hour
= [tex]\dfrac{2}{3}[/tex] hour
We know that,
[tex]Speed=\dfrac{Distance}{Time}[/tex]
[tex]Speed=\dfrac{25}{\dfrac{2}{3}}[/tex]
[tex]Speed=\dfrac{3\times 25}{2}[/tex]
[tex]Speed=\dfrac{75}{2}[/tex]
[tex]Speed=37.5[/tex]
Therefore, the driving speed of Jacky is 37.5 km per hour.

Many proteins are regulated by the binding of GTP or GDP. Which form is the active state of the protein
Answer:
GTP-bound form
Explanation:
Such a receptor may be associated with the GDP-regulated G-stimulant protein system. When the neurotransmitter binds to the receptor, the protein G-GDP complex is activated by separating its β subunit. When the ligand "sticks" to it, it releases GDP and allows GTP to bind. This form of the G protein that binds GTP, is the activated ("on") form of it. When it is "on" it releases signals into the cell. After a short period (seconds or less) the G protein hydrolyzes the GTP to GDP and itself "turns off".
