By definition, a halo is a part of a galaxy wherein it mainly consists of scattered stars forming bulges having a significantly spherical structure. In addition, the galactic structure is commonly made up of old and metal-rich stars forming clouds of gas and dirt at the spirals of a galaxy.
Answer:
Latent period.
Explanation:
Immediately following the arrival of the stimulus at a skeletal muscle cell there is a short period called the Latent period during which the events of excitation-contraction coupling occur.
The period of incubation, the interval preceding exposure to a pathogen, toxin or radiation, and when effects occur. Muscle contracting, the time between a nerve stimulus, and muscle contraction.
Answer:
7.60× 10^6 V/m
Explanation:
electric field strength can be determined as ratio of potential drop and distance, I.e
E=V/d
Where E= electric field
V= potential drop= 74.0 mV= 0.07 V
d= distance= 9.20 nm = 9.2×10^-9 m
Substitute the values
E= 0.07/ 9.2×10^-9
= 7.60× 10^6 V/m
