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.
Cells use Lipids when Carbohydrates are not available. <span />
Answer:
Values are a culture's standard for discerning what is good and just in society. Values are deeply embedded and critical for transmitting and teaching a culture's beliefs. Beliefs are the tenets or convictions that people hold to be true
Nicotine in smoke has two forms; the electrically neutral form is more easily absorbed through the mucous membranes of the mouth, nose, and lungs.
<h3>Where is nicotine absorbed the most?</h3>
- Nicotine is absorbed through mouth mucous membranes and reaches peak blood and brain levels more slowly in people who do not inhale the smoke, such as cigar, pipe, and smokeless tobacco users.
- By "riding" in with the tar that is inhaled from a lit cigarette, nicotine enters the body. About 8 seconds after inhaling the smoke, the nicotine/tar mixture enters the lungs, where it is swiftly absorbed. It can move to the brain once it reaches the bloodstream.

Answer:
C) Y
Explanation:
The horizontal axis of the cladogram depicted below is a timeline that extends from 100,000 years ago to the present; the vertical axis represents nothing in particular. The labeled branch points on the tree (V-Z) represent various common ancestors. Let's say that only since 50,000 years ago has there been enough variation between the lineages depicted here to separate them into distinct species, and only the tips of the lineages on this tree represent distinct species.
- Y is the common ancestor of the greatest number of species, both living and extinct.
- V is the common ancestor of the fewest number of species.
- Eleven Species are both living and extinct, are depicted in this tree
- Evolutionary trees such as this are properly understood by scientists to be a hypothesis.
- Lamarck and Wallace are the two scientists below would probably have agreed with the process that is depicted by this tree.
