The build up in the child's ear prevent sound from reaching the eardrum.
The correct answers are options:
1. Amphibians evolved before land reptiles.
4. Elephants appear in the fossil record after dinosaurs became extinct.
The relative dating is a technique of dating with respect to any past event. In this case, two events are discussed to be occurred in a sequence related to one-another. In the option 1, the amphibians are said to be evolved before reptiles. So, the evolution of the amphibians is relatively dated with the evolution of reptiles. Same in the option 4, the evolution of the elephants is relatively dated with the extinction of the dinosaurs.
Answer:The predicted population of brain coral in a reef covering 120m² is ; ≈ 40
First step : Calculate the value of the default population density
Population density = population size (dive 1) / total area
= 4 / 12 = 0.33
Total area ;
∑ Area of each reef quadrant = length * width = 2 * 2 = 4m²
∴ Total area = 4 + 4 + 4 = 12m².
Final step : Determine the value of the predicted population of brain coral
Population density = ( predicted population ) / predicted area
0.33 = ( pp ) / 120m²
∴ Predicted population ( pp ) = 0.33 * 120
= 39.6 ≈ 40 brain corals
Hence we can conclude that the predicted population of brain coral is 40
