Answer:
The correct answer is B An enzyme binds to the substrate at enzyme"s substrate site.
Explanation:
Enzyme is proteinecious in nature and act as homogenous biological catalyst.Enzyme contain an active site or substrate binding site to which specific substrate binds.
The active site of an enzyme contain many amino acids such as cystein,histidine,aspartic acid ,glutamic acid.These amino acids contain functional groups such as -SH group,-OH group,-COOH group. These functional group facilitate the binding of substrate to the active site of an zymes.
<u>Answer</u>: The marsh rabbit population will decline and eventually it may even become extinct.
<u>Explanation</u>: The Burmese python is an invasive species hat has had a large negative impact on ecosystems such as the Everglades. This species does not have a natural predator within US and thus it has no natural means of population control.
Without this, the pythons are free too feed and reproduce at alarming rates. Among their prey species is the marsh rabbits. Although these have a high reproductive rates, it has been proven that their population decline is due to the Burmese pythons.
As with many other species, it is probable that the marsh rabbits will become extinct due to the presence of this invasive predator. Furthermore, it seems that scientists have not been able to find a method to eradicate the infestation of Burmese pythons. Thus, it is a growing problem that has catastrophic consequences on fragile ecosystems such as the Everglades.
