Macy observes the lake near a park is covered in green slime. over a few days she sees that the fish in the lake have started dying. what could
be a possible cause of this situation?
o
a.
the acid level of the lake has increased.
o
b.
an algal bloom has drained the lake of oxygen.
o
c.
industrial chemicals have poisoned the lake.
o
d.
the sediment level of the lake has increased.

(A) An algal bloom has drained the lake of oxygen.

Explanation:

Because "green slime" is algae and it needs oxygen just like the fish.

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
