Which types of cells do not reproduce and, if damaged by injury or disease, are lost forever?
Bezzdna [24]

The lack of centrioles in nerve cells prevents them from undergoing mitosis and meiosis, which prevents them from dividing. Nerve cells do not divide throughout their lives and do not lengthen without doing so.

<h3></h3><h3>What is nerve cells?</h3>

The central nervous system is constantly receiving information about the external and internal environment (in the form of sequences of action potentials) from nerve cells, also known as neurons.

Nerve cells are “excitable” cells that may convert a range of stimuli into electrical impulses (CNS). Despite the complexity of the nervous system, neurons and glial cells are the only two types of nerve cells that make up nervous tissue.

The structural and operational components of the nervous system are called neurons. Nerve impulses are electrical signals that are transmitted by them. Neuronal support is provided by glial cells.

Therefore, nerve cells do not reproduce and, if damaged by injury or disease, are lost forever.

To test acidity levels of water, scientists test its pH. As acid rain falls, the pH Levels in lakes and streams decreases. Candi
Gnom [1K]
Can you please put the graph in the question so I can see it?

Acids have a pH level power than 7. Water is usually close to 7 pH, but it is usually diluted because of various factors. I'm assuming you mean the pH of the sample was 5.4? This would make more sense. The acid rain would lower the average pH because the rain has a pH less than 7. The rain's pH will also be less than 5.4 because it would need to average with the waters previous pH to get this number.
