Answer:
Floodplains are identified as zones on FEMA Flood Insurance Rate Maps (FIRMs). Flood zones are defined by type, depth, and frequency of flooding. But the shape and nature of a floodplain may also change over time as the main channel of a river naturally migrates through erosion and accretion, impacting how and where excess water may first over top the banks of the river during a flood event. Geologically ancient floodplains are often represented in the landscape by fluvial terraces. These are old floodplains that remain relatively high above the present floodplain and indicate former courses of a stream. I HOPE THIS HELPS YOU :)

Question is incomplete. Complete question is as follows:
You have decided to determine how many microbes are living on the lettuce in the salad bar at your favorite restaurant. You place 1 gram of lettuce and 99 mls of water in a blender and blend the mixture. This is sample A. You then transfer 1 ml of this dilution into to another that contains 9 mls of water. This becomes sample B. You next transfer 1 ml of sample B into a separate container that contains 9 mls of water. This is sample C. Next you transfer 1 ml each from samples B & C onto separate nutrient rich agar plates, swirl, let harden and incubate at 37C. When you examine the plates after 48 hours you find 110 colonies growing on plate C. How many microbes were living on that 1 gram of lettuce?
Answer:
1.1x10^6 microbes
Explanation:
When 1gm of lettuce is mixed with 99 ml of water, the microbe concentration is diluted 100 times (Sample A). 1 ml of sample A is mixed with 9ml of water to make sample B which further dilutes microbe concentration 10 times making the total dilution 1000 times. This process is repeated with sample B to make sample C increasing the dilution to 10000 times.
110 colonies are counted from this sample C. Each colony signifies a single microbe during plate counting method. So, 110 microbes were present on the plate. Original number of microbes = microbes counted * times of dilution =
110 * 10000 = 1100000 = 1.1x10^6 microbes
The Florida Reef System (FRS) is the largest coral reef ecosystem in the continental US, with its extensive shallow coral reefs that span 358 miles from the Dry Tortugas near Key West, north along the Atlantic coast to Martin County.
