If researchers use only the number of coral found in dive 1, calculate the predicted population of brain coral in a reef that covers 120m squared. i forgot how to do this :))

40

Explanation:

Each quadrant measured = 2m X 2m

Length = (2+2+2) m = 6m

Width = 2m

Total area = area of (quadrant 1 + quadrant 2 + quadrant 3)

Total area = 6 * 2 = 12 m^2

Number of coral found in dive 1 = 4

Population density = 4/12 = 1/3 (0.33)

Now,

=> Population density = (Predicted population)/area

=> 1/3 = PP/120

=> PP = 120/3 = 40

So, the required answer is 40.

search in internet u can get it

answer : haversian

[explanation: -(compact bone is organized as parallel columns, known as haversian systems, which run lengthwise down the axis of long bones. these columns are composed of lamellae, concentric rings of bone, surrounding a central channel, or haversian canal, that contains the nerves, blood vessels, and lymphatic system of the bone)]
