Answer:
New cells arise from existing cells.
Explanation:
According to the cell theory, "all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells"(Lumen Learning).
Cells are the basic unit of life. Some organisms consists of only one cell while other organisms have many cells and are called multicellular organisms.
In multicellular organisms, new cells are formed by the division of preexisting cells.
Answer:
Explanation:
The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged). Atoms have different properties based on the arrangement and number of their basic particles.

Answer:
696g
Explanation:
To determine the mass of ethylbutanoate produced, it is important that we know the number of moles of ethylbutanoate produced.
Now from the chemical equation, it can be seen that one mole of ethanol produces one mole of ethylbutanoate. This means that 6.0 mol of ethanol will surely produce 6.0 mol of ethylbutanoate.
Now, we need to get the mass of ethylbutanoate produced. The mass of ethylbutanoate produced is the number of moles of ethylbutanoate produced multiplied by the molar mass of ethylbutanoate produced.
The molar mass of ethylbutanoate is 12(6) + 12(1) + 16(2) = 116g/mol
The mass thus produced is 116 * 6 = 696g
