Neighborhoods in coastal areas use algaecide in their ponds to control algae growth. The algaecide interferes with the algae's ability to conduct photosynthesis which kills the algae, allowing the pond to look clean. When there is a large rainstorm, the algaecide runs off into the local area streams. This water eventually runs out into the ocean. What is the likely outcome of the algaecide getting into the oceanic ecosystem? A. Plants will decrease in number
B. Plants will increase in size
C. Increase in the number of zooplankton
D. Increase in the size of the fish

shield volcanos are angry and get mad over the smallest things so much that there heads erupt   pahoehoe and a'a lava. a composite volcano is the poller opposite of a shield volcano. its   peaceful thing and knows how to control its emotions.      

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
