The most generally accepted form of conclusive evidence for the theory of Evolution is the fossil record.
<h3>What is the theory of Evolution?</h3>
- The theory of evolution was proposed by Charles Darwin.
- It states that as time passes, organisms evolve to better adapt to their environments.
- This is closely related to natural selection, which is considered a <em><u>driving force of </u></em><em><u>evolution</u></em><em><u>. </u></em>
<h3>How the fossil record supports this theory</h3>
- The fossil record provides essential data to support this claim.
- The data comes in the form of the comparison between fossils of two closely related organisms, separated by a matter of generations, that <em><u>present changes in the genetic code that made them more apt for survival.</u></em>
Therefore, we can confirm that the most generally accepted form of conclusive evidence for evolution is the presence of <u>fossils </u><u>that show the genetic correlation between two organisms and the progression of </u><u>evolution </u><u>between them. </u>

Molecules undergo London dispersion forces:
is the molecule will undergo only London dispersion forces when interacting with other molecules of the same kind.
What are London dispersion forces?
- A sort of force that interacts between atoms and molecules that is often electrically symmetric is referred to as a London dispersion force.
- When viewed from the nucleus, their electron distribution is frequently symmetrical. This dispersion force, which is also known as a transient attractive force, is frequently observed when the locations of the electrons in two nearby atoms cause the atoms to temporarily form dipoles.
- The bond is polar when there are significant variations between the elements' electronegativities; it is nonpolar when there are similarities. When the molecule's dipole moment is equal to O, it is nonpolar; when it differs from O, it is polar.
- The force at these molecules is known as the London dispersion force. In nonpolar molecules, the forces are weak, and partial charges must be induced so that they can bond. In polar molecules, partial charges caused by polarity result in a stronger link known as a dipole-dipole. The dipole-dipole is significantly stronger and known as a hydrogen bond if it is connected to a large electronegative atom (F, O, or N). Ionic force is the name for the attraction force at ionic substances.
- The intermolecular force in the letter an is the London dispersion force because the compound is nonpolar;
<u>Reason for incorrect options:</u>
b: the compound is ionic because Na is a metal and the other part is covalent,
c: two compounds are possible: one is nonpolar and exhibits London dispersion force; the other is polar and exhibits dipole-dipole force; and
d: both compounds exhibit hydrogen bonds (H bonded to O, and H bonded to F).

Answer:
0.68 V
Explanation:
For anode;
3Mg(s) ---->3Mg^2+(aq) + 6e
For cathode;
2Al^3+(aq) + 6e -----> 2Al(s)
Overall balanced reaction equation;
3Mg(s) + 2Al^3+(aq) ----> 3Mg^2+(aq) + 2Al(s)
Since
E°anode = -2.356 V
E°cathode = -1.676 V
E°cell=-1.676 -(-2.356)
E°cell= 0.68 V
The density of the unknown material is 0.213 ml/g
<h3>
Apparent density of the unknown material</h3>
The apparent density of the unknown material is calculated as follows;
Volume of the unknown substance = 126 ml - 102 ml = 24 ml
Density of the unknown substance = mass/volume
Density of the unknown substance = 24 ml / 112.6 g
Density of the unknown substance = 0.213 ml/g
Thus, the density of the unknown material is 0.213 ml/g
