When considering human impacts to ecosystems, identify the incorrect statement:
Select one:
a. cod, swordfish, halibut and mackerel populations are especially vulnerable to collapse
b. coral reefs providing critical habitat and sources of food for tropical fish are slowly recovering, due to successful enforcement of fishing quotas
c. aquaculture may provide a sustainable alternative for raising farmed fish to feed a growing human population, allowing ocean fisheries to recover
d. over half of global ocean fisheries populations have become severely overharvested within the past century

coral reefs providing critical habitat and sources of food for tropical fish are slowly recovering, due to successful enforcement of fishing quotas

Explanation:

This is a wrong statement because coral reefs contrary to the statement is not recovering, Over-fishing an destructive fishing,(to meet up with increasing demand) are some of the human impacts  reltively control by  the enforcement.

But,acidification  (eutrophication),  and  mass coral bleaching from global warming  are not restricted by the enforcement  of fishing quotas and  are drastically reducing the population of the reefs.This in turn affecting the survival of the fishes, reducing the population,

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.

hi, natural selection of the peppered moth during the industrial revolution in 19th-century england is an example of an outlier in the study of evolution. during this time, pollution from factories filled the forests, coating trees in a layer of soot—turning white trees black
