Identify the type of interaction described in each scenario. sociable weavers are a species of bird found in africa. all males of a colony work together to build a large nest that can house several hundred birds. this is an example of  cooperationx competitionpredation. typically, peregrine falcons hunt medium-sized birds, but they will also eat small mammals, reptiles, and insects. this is an example of  x .male deer, called bucks, head-butt each other to defend their breeding territory and female mates. this is an example of  cooperationcompetitionx predation. 

the dna of humans and mice is almost 92% similar. this similarity indicates that . mice have a tail, while humans have a tailbone. the tailbone is a structure in humans.yes it's true.

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
