The clear area around the paper disc soaked in spot lotion indicates that the spot lotion has antibiotic properties that inhibit bacterial growth. The active ingredients in the lotion diffuse outwards from the disc, creating a zone of inhibition where bacteria are unable to grow.

Beans soaked in water microorganisms?

Soaking beans in water can create a favorable environment for microorganisms to grow, including bacteria and molds. To prevent this, it's recommended to rinse the beans and change the soaking water periodically to inhibit bacterial growth. Additionally, cooking the beans at the proper temperature can help eliminate any harmful microorganisms.


What is the difference between a dry seed and a soaked seed?

A dry seed has not absorbed water and is in a dormant state, while a soaked seed has absorbed water and has started the germination process. When a seed becomes soaked, it swells as it absorbs water, triggering biochemical changes that allow it to start sprouting.


What happen if the bone soaked in water?

Nothing really. Bone material is insoluble in water in normal conditions (think about what could not happen if it wasn't!). Bones on the sea-floor in very deep water eventually dissolve though - some of the most startling, and poignant, photographs that have been taken of the debris around the wrecks of the 'Titanic', etc are of pairs of leather shoes marking where their wearers had come to rest. The entire bodies including the skeletons, and all other clothing, had disappeared.


In what way does baked bones or bones soaked in acid resemble the bones of a child with rickets?

Baked bones and bones soaked in acid become more fragile and pliable, similar to the bones of a child with rickets. Rickets is a condition where bones are weakened and can bend and deform easily due to a lack of vitamin D, calcium, or phosphorus. The changes in the structure of baked or acid-soaked bones can mimic the characteristics of rickets in terms of flexibility and weakness.
