Cells could sense and respond to electromagnet signals such as light and mechanical signals such as touch. Cells often communicate with each other using chemical signals.
<span>Natural selection is what allows a population to adapt because the animals that adapt are the ones that mate and pass along their genes. Without natural selection, evolution or adaptation would not be able to occur.</span>
Osmosis: movement of water molecules from an area of higher concentration to an area of lower concentration through a semipermeable membrane.
Osmosis calculations: equation is π=iMRT
π is not equal to 3.14159 in this situation. π stands for the osmotic pressure and is usually expressed in the pressure unit of atmospheres.
Diffusion: the random movement of molecules from an area of higher concentration of those molecules to an area of lower concentration.
Prokaryotic cells: unicellular organisms that lack organelles or other internal membrane-bound structures.
Eukaryotic cells: organisms whose cells have a nucleus enclosed within membranes, unlike prokaryotes.
Mitosis: cell division in which the nucleus divides into two nuclei containing the same number of chromosomes with an end result of two identical cells.
Stem cells: an undifferentiated cell that is capable of dividing and giving rise to one or more distinct types of specialized cells.

Answer: Glucose (and also oxygen)
Explanation: Photosynthesis is the process of turning CO2 and H2O in Glucose and oxygen where the chloroplasts use the energy from the sun to rip apart the molecules and rearrange them into glucose, a useable form of energy, and oxygen, a bi product that gets released into the atmosphere.
