Answer:
The pH scale has been drawn below.
Explanation:
pH sacle may be defined as the scale that determines the pH of acids and bases. 0 represent the neutral compounds. The compounds that pH less than 7 acts as acid whereas the compounds that have pH greater than 7 acts as base.
Here, water is neutral, Hydrochloric acid (HCl) is acidic and sodium hydroxide (NaOH) acts as base.
Water, hydrochloric acid, and sodium hydroxide can be placed on the pH scale as follows:
Water: Water is considered neutral and has a pH of 7. It falls in the middle of the pH scale.
Hydrochloric acid: Hydrochloric acid is a strong acid and is highly acidic. It has a pH below 7. The exact pH value of hydrochloric acid may vary depending on its concentration, but it typically falls within the range of 0 to 2.
Sodium hydroxide: Sodium hydroxide is a strong base and is highly alkaline. It has a pH above 7. Again, the specific pH value of sodium hydroxide can vary based on its concentration, but it typically falls within the range of 12 to 14.
So, on the pH scale, water would be placed at pH 7 (neutral), hydrochloric acid would be placed below pH 7 (acidic), and sodium hydroxide would be placed above pH 7 (alkaline).

Explanation:
It is a historical artifact that scholars spent too much time trying to understand.
It is something that is interesting to learn about, but it is not historically significant.
It is a piece of 5 that has an exciting and entertaining story.
The right option is; It is a fascinating artifact that can help people better understand the past.
Rosetta Stone is an ancient Egyptian stone discovered by a Frenchman called Bouchard in August 1799. The stone has inscriptions written in two languages (Egyptian and Greek) and in three writing systems (hieroglyphics, demotic script and the Greek alphabet). The inscriptions on the stone were written by a group of priests in Egypt to honour the Egyptian pharaoh. The inscription contains all the good things that the Egyptian pharaoh did for the priests and the people during his reign.
Answer: A
Explanation:
It contains a membrane–bound nucleus, a large central vacuole, a cell wall, a cell membrane, and chloroplasts.
B. allow you to view living cells, while light microscopes do not
C. have higher resolution that allows you to view smaller specimens
D. allow you to view the true colors of the specimens being viewed
2. What would be the best microscope to view living single-celled organisms in a sample of pond water?
A. Transmission electron microscope
B. Scanning electron microscope
C. Compound light microscope
D. Dissecting microscope
An advantage of electron microscopes compared to light microscopes is that electron microscopes have higher resolution that allows you to view smaller specimens
The best microscope to view living single-celled organisms in a sample of pond water is called the Compound light microscope
For better understanding, we have to understand what electron microscope and compound light microscope is.
From the above, we can say that An advantage of electron microscopes compared to light microscopes is that electron microscopes have higher resolution that allows you to view smaller specimens and
The best microscope to view living single-celled organisms in a sample of pond water is called the Compound light microscope answers are true

I just took this test these are both right.
Answer:
Cell membrane is also called as semi permeable membrane.
Explanation:
It allows some chemical compounds to pass through and stops the other from their entry.
