Answer:
a mixture
Explanation: A mixture consists of different atoms that are not chemically bonded. It is of two types of the heterogeneous mixture and homogeneous mixture. The chemical substances can be differentiated visually in the heterogeneous mixture.
In a mixture, the proportion of atoms can be slightly changed without changing or modifying any substance. This is because the individual substances in mixture keep their properties when mixed together. Further, mixtures have variable compositions and substances. these mixtures can be are separated using physical methods.

Answer:
2 Smooth yellow : 1 smooth green : 1 wrinkled yellow : 0 wrinkled green
Explanation:
The cross between a true breeding smooth green and a true breeding wrinkled yellow produced a homogeneous smooth yellow F1 . According to Mendel's Law of Dominance, the traits that appeared in the progeny are dominant.
The parents were true breeding, so they are homozygous for all genes.
If the genes are linked, their genotypes can be written as:
smooth green X wrinkled yellow
<h3>
Sy/Sy X sY/sY</h3><h3>
F1: Sy/sY</h3><h3>
</h3>
The F1 is self-fertilized, so a cross Sy/sY x Sy/sY is done. If the genes are very tightly linked, almost no recombination happens between them and all gametes will be parental.
The F1 individuals can produce 2 types of gametes then: <em>Sy </em>and <em>sY</em>.
The expected offspring would be:
- 1 Sy/Sy: Smooth green
- 2 Sy/sY: Smooth yellow
- 1 sY/sY: wrinkled yellow
