Stephanie wants to measure the volume of an irregularly shaped object. Which of the following describes the steps that would need to be followed in order to do this?
A.
Fill a graduated cylinder halfway with water. Drop the object into the water. Measure the new volume of water. Subtract the initial volume of water from the final volume of water.
B.
Fill a beaker with water. Measure the initial mass of the beaker. Place the object in the beaker. Subtract the initial mass of the beaker from the final mass of the beaker plus the object.
C.
Measure the length, width, and height of the object using a ruler. Multiply these measurements together to find the volume of the object.
D.
Measure the mass of the object on a balance. Measure the height of the object using a ruler. Multiply these measurements together to find the volume of the object.

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
