PLEASE HELP MEEE I WILL MARK BRAINLIST FOR THIS ITS SUPER SIMPLE.BUT U MUST TYPE EVERYTHING all I need you to do its to type out these pictures word for word it pretty simple

Population Changes

Change is inevitable in nature.

Ecosystems have to cope with sudden changes like hurricanes and long term changes like ice ages.

Healthy Ecosystems will withstand the stress caused by change. Populations will recover or adapt to a new climate.

Population Changes

Stressed ecosystems do not handle change well.

They are already fragile or out of balance. They react with population spikes (boom) and population crashes (bust)

Population spike (boom)- Increase in population happens quickly.

Population crash (bust)- Decrease in population happens quickly

Sometimes a stressed ecosystem will not recover from change.

Population Effects Ecosystems

If a change affects one population in an ecosystem, the change will be felt throughout the system over time.

When one population of organisms increases or decreases, other populations will be affected because all living things are interrelated.

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml

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.
