Answer:
Answer is B. Positive feedback regulation can generate an abrupt, all-or-none response in which the cell moves from ignoring a signal to responding to it very strongly.
Explanation:
Positive feedback can be described as an example of feedback, which is a natural mechanism that amplifies the action of a system.
It can be better be explained further, as a situation whereby the blood pressure decreases and the response of the body also makes or causes the blood pressure to decrease the more.
Other examples of a positive feedback also include blood clotting, ripening of fruits , uterus muscle contraction, resulting to the stretching of the uterus during pregnancy.

Answer: 77.0J
Explanation:
The magnetic field is given as 4.40T
Since the volume is not given, we assume that the volume is 10.0cm³
We need to find the magnetic field energy in this volume.
The energy density is:
u = B²/2u•
u• is given as 4π × 10^-7 T.m/A
Using this formula we substitute
u = B²/2u• = (4.40 T)²/ 2(4π × 10^-7 T.m/A) = 7.704 × 10^6 J/m³
The energy is equal to the energy density multiply by the volume. You get;
U= uV = (7.704 × 10^6 J/m³) × (10.0 × 10^6m³) = 77.0J
