Define the following vocabulary words:
Speciation - is the formation of new and distinct species in the course of evolution
Mutation - a permanent, heritable change in the nucleotide sequence in a gene or a chromosome
Cladogram - a branching diagram showing the cladistic relationship between a number of species 2. Define “adaptation” in your own terms and give an example
Adaptation is a process where an animal or plant goes through a genetic mutation so it can be better fitted in the environment. An example of adaptation are the plants that live in hot and dry deserts. The plants have to go through a mutation where it is able to adapt to the hot climate. The plants are able to adapt in the desert because the plants …show more content…

I predict 1.0% petri dish will have half their eggs hatched but the other half it will not hatch. Same thing as 0.5% petri dish I believe that the brine shrimps live in a higher concentrated salt water. I predict the 1.5% petri dish will have the most brine shrimps swimming around because the water is a better suited environment for the brine shrimp.

Title: Suited Waters for Brine Shrimps
Objective:
Examine 3 different natural selections using brine shrimp and salt solutions. It will test the hatching viability of roughly 20 brine shrimp eggs in three different NaCl solutions over the course of 48 hours.
Hypothesis:
If there is a higher concentration of NaCl in the solution, then the hatching viability of the brine shrimp will increase.

I think a higher concentration of NaCl in a solution will result in a higher hatching viability because I’ve researched that brine shrimps live in high concentrated salt waters, such as the Great Salt Lake of Utah which has a great amount of salt in the waters. So, I believe that the petri dish with 1.5% of saline solution will be the closest related to an an actual environment brine shrimp live in. The population is influenced by the amount of salt in the water so if there is more salt than the hatching viability will be
