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
Explanation:
Answer:
Competition.
Explanation:
The interaction between the organisms can be beneficial harmful or neutral depending on the types of organisms. Different types of interaction are mutualism, ammensalism and commensalism.
The competition occurs when the individual compete for the same resources or for the habitat. The competition results in the exclusion of one species and determines the distribution of other species.
Thus, the answer is competition.
<span>Survival of at least a few members of a population after a major environmental change is most dependent on 3) variations in many different traits in many individuals in the population.
Variation is important for a species which wants to survive huge changes in the environment. If they cannot adapt to their new surroundings, they won't be able to survive. This is where variation comes in - it enables a species to develop new techniques and traits necessary for survival.

The patient does
not respond adequately to fluid replacement and
was given an IV infusion of dopamine hydrochloride at 5 mcg/kg/minute. In addition, to
monitor that the drug is having the desired effect, the nurse should assess the
client for increased cardiac output. <span>At medium doses, which is between 4 – 8 mcg/kg/min, the dopamine
hydrochloride slightly increases the heart rate and improves contractility to
increase cardiac output and recover tissue perfusion.</span>
