Seismic gaps are places where scientists think that ________.
Elis [28]
The answer is Faults are storing elastic strain. To simplify, seismic gaps are places where scientist think that faults are keeping elastic strain. In addition, scientists think that stress on a fault constructs up to a critical point and is then unconstrained as an earthquake. The seismic gaps are areas in which no earthquakes have occurred over a long period of time and therefore are probable to be under a high volume of stress.

Many foods must be refrigerated to prevent spoiling (microbial growth). Explain why honey (which is ∼82% carbohydrate by weight)
VLD [36.1K]

Answer;

-Honey contains a considerable amount of sugar (about 82% carbohydrate) and therefore when a microbe (e.g., a fungal spore or bacterium) lands on honey the process of osmosis causes water to be drawn out of the microbe thus blocking its ability to live and proliferate.

Explanation;

Antibiotics are used to kill or inhibit bacteria growth. Honey contains hydrogen peroxide, which may account for some of its antibacterial properties. It also has a high sugar content, which can help stop the growth of certain bacteria.

-Additionally, honey has a low pH level. This works to pull moisture away from bacteria, causing the bacteria to get dehydrated and die off.
