What are the two forces that act on the orbit of a planet? Orbits of other planets and gravity between sun and planet.
Gravity between planet and sun and the velocity of the sun.
Velocity of planet and gravity between sun and planet.
Gravity between the aphelion and perihelion.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.

the answer is c.) there is a warm front in region a and a stationary front in region b.

straight or amphibians are homeothermic to thermal

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community
