In 2012, astronomers reported the discovery of a planet

that revolved around to Sun-like stars Kepler 345, a

gaseous planet, revolves around the stars every 289

days and the stars revolve around each other every 28

days. This information was presented in the January 11,

2012 issue of the joumal Nature

Based on the information in the article, which title

would be most appropriate?

New Planet Found in Open Cluster System

New Planet Discovered in Binary Star System

Discovery: New Globular Cluster and Planet

Discovery: Star System Orbiting New Planet

the correct answer is option b

behavioral response need communication and thus co-ordination at several levels such as interaction among cells, organ system and the entire organism.

behavioral response produces both internal and environmental stimulus.

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.
