The pH of seawater is about 8.1, making it alkaline.
The average pH of sea water is about 8.1 but it can also range between the pH value 7.9 to 9.0 as the result of the various activities that happen in the water. At this pH range, HCO3 ions are the major ions that are present, but as the pH of the water increases, the carbonate ions levels also increases, thus, when carbon dioxide dissolves in water it makes the water to become acidic.
Relative age dating<span> is the science of determining the relative order of past events using comparative data, which does not necessarily determine the </span>absolute age<span>. It proposes an estimated age, using the data of what has been more recently deposited on the surface, and fossils age is compared to the estimated age of the rock and residue in the area being excavated.</span>
"P-Waves" <span>compress and expand rocks in the direction the waves travel
In short, Your Answer would be Option A

HEYA!!!!
Under normal light conditions auxins are spread out in the plant. But when sunlight varies, auxin is broken down on the sunnier side of the stem. The higher concentration of auxin on the shady side causes the plant cells on that side to grow more so it bendstoward the light.
Hope it helps you......
