Well, first of all, the colonies growing on the surface of the agar medium are aerobic . . . that is, they need air - Oxygen - to survive. The anaerobic colonies growing within the agar medium may simply be slower growing or maturing, for some reason. Perhaps that is simply due to their being anaerobic.
In wave motion, the media are said to be liquid and solid according to the states of media themselves, that is, if a medium is in solid state then the medium is said to be solid medium and if the medium is in liquid state, then the medium is said to be liquid medium.
A growing medium is a substance in which plants are grown, providing support and nutrients for their roots. Common types include soil, coco coir, perlite, and vermiculite. The choice of growing medium depends on the type of plants being grown and the specific growing conditions required.
Straw!,
a medium
Yes bacterial colonies growing on agar plates tend to metabolize the medium leaving "fermented" waste products that are generally of foul odor. You should also be able to spot clusters of spots forming to confirm this hypothesis
broth medium
Growing plants in aquatic medium is called hydroponics
The Middle Colonies had a milder climate than the New England Colonies. Winters were not as harsh and there was less snowfall. The growing season was longer in the Middle Colonies due to the milder climate.
The surface colonies on a pour plate larger than those within the medium especially aerobic bacteria within the medium would be a restriction of growth. The restriction of growth would be due to the lack of oxygen.
broth medium
Bacterial colonies are defined as the assamblage of bacteria growing on a solid surface such as the surface of an agar culture medium, the assemblage often is directly visible, but also may be seen only microscopically.
