Endocrine disruptors are best described as _______.
Inessa [10]

Answer:

Endocrine disruptors are the synthetic or natural chemicals that may interfere with the functioning of the endocrine system in the human body. These chemicals mimic the naturally occurring hormones produced in the body like estrogen (a female sex hormone) and androgen (a male sex hormone) also these interfere with the production of the thyroid hormone. They bind to the receptors present in a cell and prevents the endogenous hormone from binding. The normal signaling process fails to respond properly.

Chemicals that functions as endocrine disruptors include dioxine, polychlorinated biphenyls (PCBs), pesticides and DDT.

Explain character displacement, and provide an example.
nata0808 [166]

A line of indirect evidence of competition comes from the comparison between closely related species, whose population can be allopatric (geographically separated) or sympatric (geographically superimposed). In some cases, the allopatric populations of these species are morphologically similar and use similar resources. On the other hand, sympatric population, which are supposed to compete for resources, have body structures and use different resources. The displacement of characters is the tendency to have more divergent characteristics in sympatric populations of two species than in allopatric populations of the same two species.

An example of character displacement is the variation in size between populations of galapagos finches. Some of its populations are allopatric ( they live separately) and others are sympatric ( they live together). Peak size distributions they vary according to whether they are sympatric or allopatric.  They look more alike when they are allopathic than when they are sympatric. That is, the peak size character moves when species enter competition.
