Some cells like cardiac (heart) muscle cells and neurons cannot divide what are the implications of this on human health and wellness
Answers
The neurons, heart cells among others are permanent cells that are incapable of regeneration. It is believed that these cells are terminally differentiated and do not proliferate in the postnatal period.
Give a brief account on permanent cells.The term "permanent cells" refers to cells that are unable to divide after birth. This category generally designates human tissues that are unable to regenerate on their own, and nerve cells—also known as neurons—along with skeletal muscle and heart cells are included in it.
1. Neurons :
The conventional wisdom holds that we have all the neurons we will ever need when we are born. The fact that the brain goes through a process known as gliosis after a stroke, wherein supporting cells (glial cells) grow and take the place of neurons that have died during the hypoxic (stroke) episode, led to the development of this theory. You may have heard, however, that in recent years researchers have discovered specific groups of neurons that may continue to divide far into adulthood. Particular regions of the brain, especially the subventricular region and the hippocampus, appear to preferentially contain neurons that can still divide. Neuronal mitosis' potential to speed up recovery from an event like a stroke is still unknown.
2. Cardiac muscle cells :
The story of heart muscle and neurons is very similar. According to conventional wisdom, the heart muscle can only experience hypertrophy, not hyperplasia, like skeletal muscle. This means that while individual cells can grow larger and produce more contractile units, overall cell numbers are limited. For developed heart muscle cells, that is likely accurate. However, recently, there has been growing evidence supporting a population of so-called cardiac stem cells, which may actually be able to divide to replace myocardial that has been damaged due to a cardiac ischemia episode.

Answers
Between the years 1970 and 1976, The percentage change in the rate of exchange occurred in the German mark relative to the United States dollar is 45%
How may the rates be determined to have changed?We may see the following rates in Germany from the chart (table):
1970 rate equals 27.42
1976 rate equals 39.74
Next, the percentage change is determined using:
% change = (Final - Initial)/(Initial - Final) * 100%
This results
100% is the percentage change (39.74 - 27.42)/27.42.
Assess the quotient.
Change in percentage = 0.45 * 100%
Consider the product
Change in percentage: 45%
Consequently, there was a 45% change in the exchange rate between the German mark and the US dollar.
