Hummingbird predators would not have a food source, therefore competitive exclusion would occur and there'd be a decrease in hummingbird predators. There would also be an increase in the number of the hummingbird's prey since the hummingbird wouldn't be there to consume them. The absence of the species would mess up the rest of the ecosystem
Fluorine
Check out the periodic table. Exact mass number of Fluorine should appear as 18.99...
Use the pH color scale. It shows acidity level of both acids and bases. You dip one of the pH strips into whatever liquid you choose, and then compare the new color of the pH strip to the colors on the scale. This will tell you the level of acidity. pH scale can be found below. As you can see, the brighter colors are more acidic than the darker and duller colors.
A observation and hypothesis
Answer: 1. B-D-A-C.
Explanation: If a genetic error occurs during chromosome replication, it will lead to a series of events ranging from:
1) Production of a DNA strand with an altered base sequence.
2) Production of an mRNA strand with an altered base sequence during transcription. This is because mRNA is synthesized by copying the genetic message coded in the DNA.
3). Synthesis of a protein with an altered amino acid sequence during translation, and this eventually leads to
4). The expression of a new inheritable trait in the organism.
