Agar jelly has good moisture retention properties, making it an effective barrier against dehydration. However, it is not an effective barrier against oxygen transmission and can allow gases to pass through. Agar jelly can also absorb water and become softer over time, which may affect its barrier properties.

What process would cause acid to move through agar jelly?
Acid can move through agar jelly by a process called diffusion, where molecules move from an area of high concentration to an area of low concentration. The acid molecules will spread evenly throughout the agar jelly until they reach equilibrium.
How the amylase would spread into the agar jelly?
Amylase would spread into the agar jelly through diffusion, as the enzyme molecules move from an area of high concentration to an area of low concentration. The amylase will break down the starch in the agar jelly into smaller molecules like maltose, which will diffuse away from the point of origin.
Why do you grow bacteria on agar jelly?
Put agar jelly in a petri dish to sterilize the dish and then use something like a sterile inoculating loop to put the bacteria on the jelly. Then, seal the petri dish but make sure it is not airtight.
What is the use of agar?

Why did agar jelly and blue dye take a week for spread to happen?
Agar jelly is a dense medium that may slow down the diffusion of the blue dye molecules, preventing them from quickly spreading throughout the jelly. Additionally, the movement of molecules within the jelly may be limited due to its gel-like consistency, which could contribute to the delay in the spread of the dye.
What jelly is made from seaweed and used in glue making?

What is agar jelly?
Agar jelly is a type of jelly using the seaweed gelatin know as agar agar as a thickener. Usually it is used in Europe because it does not appeal to the American pallate for the fact that it does not melt in your mouth like gelatin or pectin.

What happens when you heat agar jelly at 120c for 30 minutes?
When agar jelly is heated at 120°C for 30 minutes, it undergoes a process called hydrolysis, where the agar's polysaccharide structure breaks down. This can lead to a loss of its gelling properties, making the jelly more liquid and less stable. Additionally, prolonged high temperatures may cause degradation of the agar, affecting its texture and clarity. If cooled afterward, it may not set properly or retain the desired firmness.
What jelly like substance can you grow microbes on the lab?
The jelly like substance is agar and is produced from seaweed. In the laboratory, the agar is placed in a Petri Dish.

What is a nutrient jelly for growing bacteria?
A nutrient jelly for growing bacteria is a solid medium made of agar and nutrients such as amino acids, vitamins, and minerals that bacteria need for growth. It provides a surface for bacteria to grow and form colonies that can be easily observed and studied in laboratory settings.
Where was the penicillin made?
