Nelda walks from the Big Pine neighborhood to school every morning. Jonah walks from the Stone Creek neighborhood to school every morning. They both leave at the same time, but Nelda always arrives before Jonah. What other information is needed to determine who walks the fastest?

cell differentiation  is how generic embryonic  cells  become specialized  cells. this occurs  through a process called gene expression. gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a  cell  functions.

explanation:

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
