<span>Dominant traits are traits that will be expressed. Recessive traits are traits that are never expressed in the presence of a dominant trait. They can only be expressed when both alleles are recessive.
This is true.
Dominant traits are just that - dominant. If they are present in the genotype, they will appear in the phenotype.</span>
Hey there!
Your answer is option A.
"Molecules of the dispersion medium colliding with dispersed phase particles" is what causes Brownian motion in colloids.
Hope this helps you.
Have a great day!
Energy level and spectral line
Explanation:
The energy levels and their spectral lines are related.
Based on the Bohr's model of the atom, he suggested that electrons occupy specific spherical orbits.
These orbits are called energy levels around the nucleus.
The spectral lines are the different colors emitted by atoms when they absorb or lose energy.
- Electrons can transition between different energy levels when they acquire enough energy that corresponds to that of the energy level
- By doing so, they emit energy in the process and this is seen as visible spectral lines.
- Spectral lines are usually studies in order to gain more information about the properties of atoms.

%
Explanation:
If we know the grams of a chemical compound in a specific reaction, it is possible to know the percentage of each atom that composes it.
For the Aluminum Oxide in this problem, we know its total weight and the grams of each component.
therefore we can determine the percentage ratio of its components through:
For Al
