Question
Chapter 4, Problem 4.44AP
(a)
Interpretation Introduction
Interpretation:
The terms molecular formula and structural formula are to be distinguished.
Concept Introduction:
Molecular formula of a compound indicates the total number of atoms present in the molecule.
Structural formula: The representation of each atom with their symbol in a bond-line structure of a compound is called as structural formula.
(b)
Interpretation Introduction
Interpretation:
The terms structural form land condensed structure are to be distinguished.
Concept Introduction:
Structural formula: The representation of each atom with their symbol in a bond-line structure of a compound is called as structural formula.
Condensed structural formula of a compound is the representation of atoms with its proportion in a molecule by using their chemical symbols.
(c)
Interpretation Introduction
Interpretation:
The terms lone pair and shared pair of electrons are to be distinguished.
Concept Introduction:
In a covalent molecule, electrons are shared between atoms and bounds are formed.
One bond is formed by using a pair of shared electrons.
Lone pair of electrons is the valence electrons of atoms in a molecule that are not participating in any bond formation.

We always include controls in the Annexin-V-GFP/Propidium Iodide flow cytometric assay to study apoptosis. List four types of controls in this assay.
Why do we need these controls? Explain your answers.
After the flow assay, if we like to examine the morphology of the viable, early apoptotic and late apoptotic cells by confocal microscopy, what can we do and what are the expected results?
3. (2 points) Your lab partner accidentally used a pen instead of a pencil to mark the baseline and label the
