If you have low blood pressure, you may donate blood as long as you feel well at the time of donation. If your blood pressure normally runs low, it may be more difficult for your body to adjust to the volume loss following donation, especially if you are dehydrated.
An aquiline nose (also called a Roman nose or hook nose) is a human nose with a prominent bridge, giving it the appearance of being curved or slightly bent.The word aquiline comes from the Latin word aquilinus (eagle-like), an allusion to the curved beak of an eagle.he flat, broad nose is ubiquitous among most populations in Africa, and is noted by nineteenth-century writers and travelers (such as Colin Mackenzie) as a mark of  Negroid  ancestry. It stands in opposition to the narrow aquiline, straight or convex noses (lepthorrine), which are instead deemed  Caucasian .
There is a scale for acids and bases just like everything else. Here are a couple of definitions you should know: Acid: A solution that has an excess of H + ions. It comes from the Latin word acidus, which means sharp or sour. Base: A solution that has an excess of OH-ions. Another word for base is alkali. Aqueous: A solution that is mainly water. Think about the word aquarium. AQUA means water. Strong Acid: An acid that has a very low pH (0-4). Strong Base: A base that has a very high pH (10-14). Weak Acid: An acid that only partially ionizes in an aqueous solution. This means that not every molecule breaks apart. Weak acids usually have a pH close to 7 (3-6). Weak Base: A base that only partially ionizes in an aqueous solution. This means that not every molecule breaks apart.
