Alexander Fleming found penicillin hard to work with because he struggled to isolate and purify the compound from the mold, which was a time-consuming and challenging process. Additionally, the mold produced penicillin in small quantities, making it difficult to obtain enough for effective use.
The tap water in Wirral is classified as hard water, containing elevated levels of minerals like calcium and magnesium. This hardness can cause limescale build-up in appliances and affect the taste of water. Consider using a water softener if you find the hardness to be a problem.
Pomegranate has a hard outer shell with a dark red pit inside. When the outer shell is cracked open, you can find the juicy arils or seeds inside, which are edible and have a sweet-tart taste.
A rinse aid with citric acid or a dishwasher detergent with built-in water softeners like phosphates are effective for hard water. Look for products specifically designed for hard water to prevent mineral buildup and ensure clean dishes. Experiment with different additives to find the one that works best for your water quality.
No, hard water does not have a distinct smell.
A scum forms when soap is used in hard water. This occurs because the calcium and magnesium ions in the hard water react with the soap to form insoluble salts, which precipitate out as a scum.
Because it was excreted too quickly by the human body, which reduced its ability to kill the bacteria.
Fleming admitted to discovering penicillin ''by accident''. That may be somewhat true, but the harder one works at research, the more so-called ''accidents'' do happen. Sir Alexander Fleming was a hard working and brilliant investigator, and this was certainly demonstrated when he became a Nobel Laureate.
Fleming did not invent penicillin, he discovered it by accident when it ruined an experiment he was doing trying to culture bacteria. It took many others and the expediency of wartime emergency funding to invent the technologies needed to mass produce penicillin as a drug. Many later antibiotics related to penicillin were later invented in labs, but penicillin is not anyone's invention as it is a natural substance made by a type of fungus.
Because he could not make it keep
it is hard to find this answer but if you really want it check out Alexandra Fleming on wikipedia.
Medicine has revolutionized in a very great way starting from the discovery of penicillin. This is as a result of the hard work of researchers and scientist who try to find lasting cures for various health conditions.
There are many answers about Alexander on this site, and you can ask for answers of other questions as well. Similarly there are answers about the Hanging Gardens in the Mesopotamia site.
Kept them in subjection and working hard.

No, penicillin is an 'antibiotic', i.e. active against bacterial caused infections. Herpes is a viralinfection and thus penicillin does not touch it. Viral infections are hard to treat (it is only the body's own defenses that really work), however there are some 'antiviral' medicines that can help.
