Answer:
Pyruvic acid is not the end product of fermentation because in fermentation the pyruvic acid is converted into alcohol/lactic acid and carbon dioxide. There are two types of fermentation alcoholic fermentation and lactic acid fermentation.
In alcoholic fermentation, pyruvate is converted into ethanol and CO2 for example in yeast and in lactic acid fermentation pyruvate is converted into lactic acid and CO2 for example in animals muscles.
Therefore in fermentation pyruvic acid is not the end product of fermentation. In fermentation 2 ATP is produced.
You can distinguish between these solutions by looking at their crystalline structure. They form different structures because one is an ionic bond and the other one is a covalent bond.
Explanation:
- Sodium Chloride (salt) is formed by giving and taking electrons, that is ionic bonding. It happens between a metal and a non-metal
- Sugars are formed between non-metals, where there is only sharing of electrons happened. It is called covalent bonding.
- Covalent bonds are stronger than ionic bonding. Hence, if you keep the solution for an hour, there forms a crystalline structure. It would be different structures since their force of attraction differs.
The discovery of fossils in graves and in archaeological digs suggest that humans were already collecting unusual shaped rocks or minerals in prehistoric times. ... Minerals were used for cosmetic purpose but also for medical use and therefore collected in the field.
The answer is D... not sure if that is correct
