Answer:
See the answer below
Explanation:
1. <u>Only one phenotype</u> is present in the F1 generation offspring. Since tallness was dominant over shortness, all the offspring in the F1 generation appeared tall.
2. <u>Two phenotypes </u>are present in the F2 generation - 9 tall and 3 short. The short trait reappeared at the F2 generation.
3. The genotype of the F1 offspring would be heterozygous. Assuming the purebred tall is AA and the purebred short is aa:
AA x aa
Aa Aa Aa Aa
All the F1 offspring will appear tall and their genotypes would be heterozygous.
4. Assuming that the allele for height is denoted with A (a), <u>the genotype of the purebred tall plant would be AA. </u>
5. In a similia vein, <u>the genotype of the purebred short plant would be aa. </u>

Answer:
The kinetic molecular theory explains the expansion of a solid material with increases of temperature as basically the result of <u>molecules moving a little farther apart.</u>
Explanation:
The kinetic-molecular theory explains the changes of state in the following way: When a solid is heated, its particles increase their kinetic energy, so that the vibration becomes more and more intense until, having reached the melting temperature, they become so weak that the particles acquire freedom of movement, that is, if we increase the temperature of a solid material system, its molecules will move faster and the average distance between them will increase, the cohesion forces decrease and there will come a time when these forces are incapable to keep the molecules in fixed positions, the molecules can move.
