I believe the answer is c
That'd be the cell wall and a permanent vacuole. You could also put chloroplasts :)
the answer to your question is chloroplast
depending on what it is for water it is 32°F
steel is 2500°F
aluminum 1,221°F
zinc is 787.2°F
sorry i cant put all the melting points
unless u mean
Melting point, temperature at which the solid and liquid forms of a pure substance can exist in equilibrium. As heat is applied to a solid, its temperature will increase until the melting point is reached. More heat then will convert the solid into a liquid with no temperature change.
Declines rapidly, increases more rapidly, reaches carrying capacity and enters a phase of exponential growth.
