Water at 4 degrees centigrade has the highest density of all other water temperatures. This is why ice (whose temperature is below 0 degrees) floats on very cold water. This phenomenon is significant in the Artic and Antarctic where ice shelves float on cold ocean waters in the poles. Animals that live in these regions (such as seals and polar bears) use these ice shelves as hunting platforms.
Answer:
C)
Explanation:
Bacteria are prokaryotic, which means they (generally) don't have organelles or a nuclear envelope around their nucleus. They have ester linkages in the phospholipids in their cell membranes, while archea, which are also prokaryotic, have ether linkages. Ether linkages are more chemically stable than ester linkages, and since archea live in extreme environments this is helpful.
Bacteria are not multicellular and do not have organelles (complex cellular structures) besides ribosomes.
Answer:
I think the answer is option 3
An individual's ecological footprint is equivalent to the: total amount of food consumed by that individual.
Solution A has 10 times more hydrogen ions than solution B.. The correct option is B.
<h3>What is a pH?</h3>
pH is the potential of hydrogen ions, or measure of hydrogen ion concentration.
It is generally used to determine the acidity and basicity of the solution based on pH scale.
The pH scale is logarithmic, which means that each pH unit contains ten times the number of hydrogen ions as the unit above it. So solution A has 10 times more hydrogen ions than solution B.
Thus, the correct option is B.
