Atomic radius, as the higher atomic numbers in 2A will have more electron energy levels, making them bigger.
The amount of atomic particles released by a radioactive material in a specific time is determined by the strong and the weak nuclear force. It is these forces that holds the nucleus of the atom and the force that needs to be overcome with to allow radioactive decay.
The blood the reaches the cells from the capillaries food and O2 pass to cells, CO2 and wastes
pass to blood. The rest of the choices do not answer the question above.
There are 3 parts of the cell theory.
1. All living things are made up of cell- This <span>means that in order for something to be alive, it must either be a cell or made up of many cells. </span>
2. Cells are the smallest units (or most basic building blocks) of life- They are are the most fundamental units of a living organisms structure. They are also the basic units of function. This means that cells carry out all of the processes necessary for an organism to survive.
3. All cells come from preexisting cells through the process of cell division- This means that in order for a new cell to be created, it has to go through cell division with cells that already exist to become a new cell.
Hope this helps :)
