Communication from a cell’s ‘environment’ to the cell will usually involve (A) a chemical messenger or an impulse and a marker protein on the cell’s surface (B) an impulse and a receptor (protein) on the nuclear membrane (C) a chemical messenger or impulse and a receptor (protein) on the cell membrane (D) a chemical messenger or impulse and a carrier molecule in the cell membrane e

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )

transformative rocks are the stones that emerge from the transformation of existing rock composes in a procedure called changeability, implies changing of structures. transformative rocks are shaped from alternate shakes that are changing a result of warmth or weight connected. one of this model is the earth developments that making rocks profoundly cover or crushed which will make the stones warmed and put under awesome weight. they are not softening but rather the minerals they are containing are changed synthetically that will shape transformative rocks. now and again different rocks are shaped when the others are near some liquid magma and getting warmed.
