Answer:
Detail is given below.
Explanation:
First of all we will understand the pH.
pH:
pH is the negative log of hydrogen ion concentration.
pH = -[logH⁺]
It means when the ions concentration increases pH will be low and when H⁺ concentration ions decreases pH will be greater. The pH range is 0-14.
If the pH is 7 the solution is neutral, if it is less than 7 the solution will be acidic and above 7 the solution is basic.
when CO₂ is added with water carbonic acid is formed and yield H⁺ ions which decreases the pH thus its color changes from red to yellow just like phenolic indicator. When phenol red is added into the acidic solution the color changes from red to yellow.
and when carbon dioxide is take off from photosynthesis process it means H⁺ ions are going to be decreased thus color changes from yellow to red.
I'm pretty sure your answer should be D. Ship Ballast. Hope this helps! =^-^=
Answer:
C
Explanation:
DNA polymerase is an enzyme, and when an enzyme is put in conditions that don't suit it, it unravels and becomes useless. Because the copy of DNA isn't being made (S phase is the copying phase, after all), cellular division will come to a stop.
Options 1st and 5th are the right answer.
Fine-grained textures commonly signify magma that quickly reduced at or near the surface of the earth. Quick cooling limits crystals from developing very big. In simple terms, texture associates to how big the single mineral grains are in the ultimate, dense rock. In most of the cases, the resulting grain dimension depends on how fast the magma chilled. 1 mm is the cutoff separating fine- and coarse-grained composition.
