The dichotomous key is not given here, however, the correct dichotomous key is as follows:
step- 1a cell has a nucleus and organelles - go to step 2
1b cell has no nucleus or organelles - bacterial cell
step- 2a cell has a cell wall - go to step 3
2b cell has no cell wall - animal cell
step- 3a cell has chloroplasts - plant cell
3b cell has no chloroplasts - fungal cell
Using this dichotomous key the cell can be identified as - Fungal cell.
A dichotomous key is an essential scientific tool that is used to find out the various kinds of organisms on their observable traits. Dichotomous keys have a series of statements with two different choices in each step that will take the student or user to the correct identification.
Identification of the given cell:
1. Follow step 1.
- If cells have a nucleus and organelles - yes then go to step 2
2. follow step 2.
- 2a. if cell has a cell wall - yes go to step 3
3. follow step 3.
- 3a. if cell has chloroplasts - no then fungal cell
Fungal cells have a nucleus and cell organelles enclosed with a cell wall around the plasma membrane but do not have chloroplast.
Thus, Using this dichotomous key the cell can be identified as - Fungal cell.

Answer: law of conservation of matter states that mass in an isolated system can neither be created nor destroyed by chemical reactions or physical transformation.
thus, the mass of the reactants in a reaction must be equal to the mass of the products
Answer:
17,932.69 g/mol is the molecular weight of the substance.
Explanation:
Using Beer-Lambert's law :
Formula used :
where,
A = absorbance of solution = 1.04
c = concentration of solution =?
l = length of the cell = 1 cm
= molar absorptivity of this solution = 18,650 
Now put all the given values in the above formula, we get the molar absorptivity of this solution.
c = 
V = Volume of the solution in L
Molecular weight of the substance = x
V = 100 mL = 0.1 L
Mass of the substance = 100 mg = 0.1 g
x = 17,932.69 g/mol
17,932.69 g/mol is the molecular weight of the substance.
