<span>This is an example of a substance changing state, a physical change, the molecules are changed, but the atoms themselves do not change, just their arrangement, and the mass of the molecules is the same. Therefor energy is absorbed by the molecules, as energy is required to change the state or physicality of a molecule structure.Hope this helps. Let me know if you need additional help!</span>
Answer:
Mitochondria are abundantly present in mammalian cells. Their fraction varies from tissue to tissue, ranging from <1% (volume) in white blood cells to 35% in heart muscle cells. However, mitochondria should not be thought of as single entities, but rather a dynamic network that continuously undergoes fission and fusion processes. In skeletal muscle, mitochondria exist as a reticular membrane network. The subsarcolemmal (SS) and intermyofibrillar (IMF) mitochondria are located in distinct subcellular regions, and they possess subtle differences in biochemical and functional properties that are characterized by their anatomical locations. SS mitochondria lie directly beneath the sarcolemmal membrane and the IMF mitochondria are located in close contact with the myofibril. Their different properties are likely to influence their capacity for adaptation. SS mitochondria account for 10-15% of the mitochondrial volume and this population has been shown to be more susceptible to adaptation than the IMF mitochondria. However, the IMF mitochondria were found to have higher rates of protein synthesises, enzyme activities and respiration (1).
Explanation:
Well, first we must remember that

This is because


So then

Answer:
How can you distinguish a physical change from a chemical change?
Explanation:
The molarity (M) of the acid in the lake water is
.
<u>Explanation:</u>
In order to estimate the concentration of a solution in molarity, then the total number of moles of the solute is divided by the total volume of the solution.
According to the given information, the formula will be applied for calculating molarity (M) of the acid in the lake water is :

Here;
are molarity of acid in the lake water and base solution respectively.
are volume of sample in the lake water and base solution respectively.
Given values are as follows:

Putting these values in above equation :




Therefore, the molarity (M) of the acid in the lake water is
.
