Answer:
a) True
Explanation:
The heart contains cardiac autorhythmic muscle cells, which are specialized cells that generate their own action potential without the need to receive it from nerve cells. These self-stimulated or self-excitable cells work together and function as the heart's natural pacemaker, which initiates an electric potential at a constant rate, and this potential travels through the heart triggering its contraction in an organized manner called the cardiac cycle.
These autorhythmic cells are found in the SA (sinoatrial) node in the right atrium of the heart, the AV (atrioventricular) node in between the atria and the ventricles, and in the fibers that connect these two nodes with each other and with the rest of the heart. All these structure working together is what's called the heart's electrical system.
Answer:
A cache memory prevents the need to type the same addresses repeatedly.
Explanation:
A cache is a storage place in which data is stored temporarily to allow faster access to this data. Also essential of a cache is that it is transparent in the sense that when data is retrieved it is not visible whether it is retrieved from the original source or retrieved from the cache, apart from the short access time.
Storing data on a faster medium to have faster access to this data is called caching. The term cache is usually used for both the data that is cached and the storage location where this data is cached.
