Answer:
Because the F1 plants all had a lowercase a/short plant allele, there was a 25% chance that two plants would contribute it to their offspring and they both did sometimes to make a aa offpsring.
Explanation:
All the F1 plants were heterozygous, so when they were crossed, the resulting genotypic ratio was 1 AA : 2 Aa : 1 aa. As you can see, this is the first time since the parent generation that there is a aa genotype and short plant phenotype, so that's why short plants reappeared.

Answer:
Electron Microscope
Explanation:
In contrast to light microscopes, electron microscopes use a beam of electrons instead of a beam of light. Not only does this allow for higher magnification and, thus, more detail, it also provides higher resolving power. The method used to prepare the specimen for viewing with an electron microscope kills the specimen. Electrons have short wavelengths (shorter than photons) that move best in a vacuum, so living cells cannot be viewed with an electron microscope.
<span>Mitosis can only happen with cytokinesis. Mitosis is the process in which a cell goes through to produce two new cell nuclei. Cytokinesis is when the cytoplasm splits. Without cytokinesis, mitosis would still happen but it would create 2 nuclei in one cell. And if cytokinesis happened and mitosis did not then the cell would most likely not survive.</span>
