Hi!
The answer would be: Dominant
<h3>Explanation</h3>
A cross between a true breeding short plant (homozygous for short, suppose tt), and a cross between a true breeding tall plant (homozygous for tallness, suppose TT) would result in all the offspring being heterozygous for the traits, meaning they would each have an allele of shortness (t) and an allele of tallness (T).
Considering the offspring were all tall, we understand that the allele for tallness must have been dominant over the allele for shortness to present itself over it. Hence, the term describing the gene for tallness would be dominant, and the term describing the gene for shortness would be recessive.
Hope this helps!

Slight differences in the color of feathers in
birds are the result of mutations. Mutation is process that occurs through a
long period of time. It is a process in which the genes’ structures changes
thus altering the physical characteristics and behaviors of species. This
results into variant forms that may be transmitted to the next generations of
species. Mutation is caused by an alteration of single base units in DNA, or
the deletion, insertion, or rearrangement of larger sections of the genes or
chromosomes. </span>
Choices 1, 2, and 3 all emit carbon dioxide, not enough to destroy the planet, but they still can cause it over a large amount of time, due to Carbon Dioxide being a greenhouse gas. Therefore, the answer is 4. Bicycles do NOT emit any carbon dioxide at all.
Generally, the sun observes a solar cycle of eleven years. In this cycle, there are fluctuations in the activity, such as the ejected levels of solar radiation, and in the appearance of the sun, such as changes in the amount and size of sun spots, solar flares and other phenomena that occur on the sun's surface.
These changes also affect phenomena on earth, especially the auroras.
