Organic molecules can be defined as carbon-containing molecules found in living things.
<h3>What are organic molecules?</h3>
They are chemical compounds that are mainly made up of carbon atoms.
<h3>Characteristics of organic molecules</h3>
- They derive their three-dimensional configurations primarily from their carbon skeletons.
- A major function of these molecules in living systems is to form the structural components of cells and tissues.
Therefore, we can conclude that the organic molecules are those that come from living beings, that is, they are compounds of biological origin, which contain carbon.

The energy of the 434 nm emission line is 4.58×10¯¹⁹ J (Option A)
<h3>Data obtained from the question </h3>
The following data were obtained from the question:
- Wavelength (λ) = 434 nm = 434×10¯⁹ m
- Planck's constant (h) = 6.626×10¯³⁴ Js
- Speed of light (v) = 3×10⁸ m/s
- Energy (E) =?
<h3>How to determine the energy </h3>
The energy of the 434 nm emission line can be obtained as follow:
E = hv / λ
E = (6.626×10¯³⁴ × 3×10⁸) / 434×10¯⁹ 9.58×10¹⁴
E = 4.58×10¯¹⁹ J
Thus, the energy of the 434 nm emission line is 4.58×10¯¹⁹ J

Answer:
B. 1.000 × 10-4 kg
Explanation:
A. 1.000 × 10-8 Mg = 0.00000001 Mg = 0.1 mg
B. 0.0001 kg = 0.1 g
C. 1000 ug = 1 mg
D. 1
.000 × 10-2 cg = 0.01 cg = 0.1 mg
A = D
B > C > A = D
