The first thing Fiona, or anyone, should do is form her hypothesis.

The hypothesis is your own proposed explanation for whatever phenomenon you're trying to study. Think of it as a predetermined idea of what could happen based on what you already know.

If a plant has a genotype of Aa, we would assume which is true?
JulijaS [17]

Answer:

4. The A allele is dominant to the a allele.

Explanation:

In genetics, the dominant allele which is expressed when present in single or two copies is always written with an upper case letter. The corresponding allele whose expression is prevented in the presence of the dominant allele is written in the "lower case letter". This is called recessive allele. In the given genotype, one copy of "A" and one copy of "a" is present. This means that the allele written with upper case letter "A" is dominant over the allele "a". Nothing can be said about the genetic trait regulated by these two alleles of a gene.

Write a summary on plant growth and how plants grow.
RoseWind [281]

Answer:

Plant grow using a process called photosynthesis. This is a process in which  green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and creates oxygen as a byproduct. The plant uses the energy from the sun in order to create energy for itself while at the same time taking up carbon dioxide and water to grow.
