Look at the photo and identify which condition of Natural Selection does it represent AND why.
Variation because it shows butterflies that can be different colors.

True or false: All the structures that embryos have in common (gills, tails, limb buds) will continue to exist when the embryos develop into full grown organisms.
False!

What does the law of superposition state?
The law states the oldest layers are on the bottom and the youngest layers are on the top.
200
What are cladograms used for?
They are used to represent the possible relationships between different organisms based on the presence or absence of certain characteristics.

F.R.I.D.A.Y

What is it called when an organism or species changes to become better suited to their environment and survive?
Adaptation

If there is 95% similarity between two organisms, what does that tell you about the number of differences when comparing their DNA?
That there are few differences between the DNA sequences since they have a high percentage of similarity.

Peacocks with the largest and brightest feathers will always have better chance at finding mates to reproduce than the peacocks with the shorter and more dull feathers. Explain what would happen to their populations overtime?
The peacocks with the large and bright feathers will increase in population because they will be able to survive and reproduce. The shorter and more dull feathers would decrease in population.

Even if your DNA and a Rhino's DNA is 88% similar, why are you not directly related?
It's because all organisms share the same genetic information. This includes DNA sequences, amino acids, and proteins.

What vocabulary words best fit the descriptions below?
(1) Structures that do the same job or function but the organisms are not related by a common ancestor.
(2) Similar structures in different organisms that have different jobs or functions.
(1) Analogous Structures
(2) Homologous Structures

The chart below compares four different species (A, B, C, and D) and shows the number of amino acid differences in a specific protein.
(1) Based on the data in the chart, which one species (A, B, C, or D) appears to be the least closely related to the others?
(2) Explain how you know!
(1) Species A
(2) Because when you compare Species A with Species B, C, and D, it has the most amino acid differences; which means it is less genetically similar and therefore less closely related to the others.
