Matter can be classified as an element, a compound, or a mixture. The elements sodium (Na) and chlorine (CI) react with each other to form the compound sodium chloride (NaCl), also
known as table salt. The reaction between sodium and chlorine releases energy. This energy
causes the temperature of the substances in the reaction to increase. When table salt
dissolves in water, a solution is formed, which is a type of mixture.
Which of these changes must happen for elements to become a compound?
elements dissolve in water
a gas becomes a liquid
elements are heated
chemical bonds form between atoms

Seen in some gram-positive bacilli, occurs when only the inner portion of a cell wall is deposited across the dividing cell. this new cross wall puts tension on the outer layer of the old cell wall. eventually, the outer wall breaks at its weakest point with a snapping movement that tears it most of the way around. the daughter cells can then remain hanging together almost side by side being held by a small remnant of the original outer wall. choose from the following statements the ones that correctly discuss reproduction using binary fission in a bacterial cell. select all that apply. view available hint(s) select all that apply. due to the stretching of the cytoplasmic membrane, both cells will contain a complete genome. each daughter cell will contain an equal number of organelles. the daughter cell will be a permanently smaller copy of the mother cell but will contain a complete genome. each daughter cell is an exact copy of the other, both genetically and morphologically
