Answer:
B. 0 m
Explanation:
The graph given is a position - time graphical model of the motion of a body.
The y-axis denotes the position of the body and the x- axis is the time taken.
To solve this problem, since the velocity of the motion is constant and no acceleration, we trace up the point 6s on the x-axis and find the y-axis equivalent.
- Completing the graph, the point lies on 0m.
- At 0m, the object would have traveled for 6s.
Answer:
ALS causes the motor neurons to gradually deteriorate, and then die. Motor neurons extend from the brain to the spinal cord to muscles throughout the body.
A signal reaches a cell mostly in the form of a signalling molecule binding to a receptor on the cell surface. This binding activates a chain of events that amplifies the signal and transfers it inside the cell. Protein kinases phosphorylate proteins and cause their activation or deactivation, or in general modify their activity. When a signalling molecule binds to a receptor, a cascade is activated and the second messengers, such as cAMP, are synthesized. cAMP molecules activate the protein kinases, which phosphorylate specific proteins and activate them.
