It is a whitening, anti-aging and revitalizing cream..
The agar will solidify and form a gel-like substance in the nutrient broth. This agar-nutrient mixture is used as a solid medium for growing and isolating bacteria in a laboratory setting.
Agar, a type of polysaccharide derived from seaweed, solidifies nutrient agar plates when it cools below 45°C. This process forms a gel matrix that helps to support bacterial growth on the surface of the plate.

Zinc does. Zinc is a naturally occurring, and needed nutrient. Having enough zinc will cause your body to make more testosterone. So one pill a day will be enough to help you raise your testosterone. If you take too much then it has negative effects on your whole body as does any other nutrient.
The gel-like substance in a pond is often algal blooms or biofilms, which are formed by the accumulation of algae and microorganisms. These substances can arise from nutrient runoff, particularly nitrogen and phosphorus, leading to excessive growth. While some algal blooms are harmless, others can produce toxins that are harmful to aquatic life and human health. It's essential to monitor and manage nutrient levels in ponds to prevent such issues.
example of gel is agarose gel,

A simple recipe for homemade gel food for goldfish includes blending cooked spinach, peas, and carrots with water to create a smooth mixture. Dissolve agar-agar in boiling water, then combine it with the vegetable mixture and pour it into a mold. Allow it to cool and set in the refrigerator, then cut it into small cubes for feeding. This nutrient-rich gel food can be stored in the fridge for several days.
Agarose gel electrophoresis.
Agar is generally made by mixing the powdered form with varying ingredients. The powder is based on seaweed extract for nutrient agar, and nutrient agar is generally a base for most other agars - eg. Horse Blood Agar is nutrient agar with horses blood added; Choc agar has defibrinated (cooked) horses blood added.
Gel
In gel electrophoresis, the stacking gel is used to concentrate and separate the samples before they enter the resolving gel. The resolving gel then separates the samples based on their size and charge. The stacking gel has a lower concentration of acrylamide, allowing for faster movement of the samples, while the resolving gel has a higher concentration for better separation.
