Why do enzymes generally only bind to one type of substrate?

Explanation:

Enzymes are proteins that increase the reaction rate that occurs within the cells.

enzymes generally only bind to one type of substrate because the active site of the enzymes has a certain shape and as per lock and key model, the enzymes have to be of specific shape the same as the substrate to get fit.  

Enzymes have active sites, where the substrate gets fits when the reaction occurs.It means that enzymes generally only bind to one type of substrate and they are highly specific for their substrate.

the answer is a) a shiprock was formed by igneous process

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.
