How can a material at a certain temperature have all of its molecules at the same energy?
pychu [463]

Answer:

The average kinetic energy of the molecules is proportional to absolute temperature. At any given temperature, the molecules of all gases have the same average kinetic energy.

Explanation:

When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. Solids, liquids and gases all expand when heat is added.

Why do you think that some bacteria/diseases are harder to eradicate than others?
Assoli18 [71]
When bacteria become resistant, the original antibiotic can no longer kill them. These germs can grow and spread. They can cause infections that are hard to treat. Sometimes they can even spread the resistance to other bacteria that they meet.

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.
