Which explanation correctly describes why it is important for a cell’s surface-area-to-volume ratio to not be too small? A. The area of the cell membrane needs to be large in comparison to the volume so the cell is able to move nutrients and wastes through it.

B. The cell would starve.

C. The cell would not produce enough waste material.

D. The organelles would grow too large to fit within the cell.

Use the table to identify the phase and phase changes of the elements under the given conditions. write the name of the substance, phase, or phase change. when the temperature in a room increases from 25°c to 33°c, changes from a solid to a liquid. in a lab, methane and nitrogen are cooled from -170°c to -200°c. the methane freezes and the nitrogen . when gold is heated to 2,856°c it changes from a liquid to a .

Plz choose one of the compounds from the table and explain how you know the numbers of atoms in your formula. is it possible for two different compounds to be made from the exact same two elements? why or why not? with a limited number of elements (less than 120 are known), does this mean we also have a small number of compounds or do we have a large number of compounds in this world?

The mass of a neutron is equal to the mass of a proton plus the mass of an electron. true or false false true
