What level of evolution happens across generations?
Microevolution
Skin, sweat, and tears are an example of this type of immune defense.
The outer body defense, or the first line of defense.
This is the term for the ability of successful survival and high reproduction.
Fitness
This term means all alleles of all the genes
Gene Pool
This type of experiment limits bias in the researcher and the participant.
What is a double blind experiment?
This type of common descent evidence includes nonfunctional or greatly reduced traits.
Vestigal Traits
The 4 signs of inflammation.
Pain, swelling, redness, heat.
What is one the four observations Darwin made that led him to the idea of natural selection?
Could be: Individuals within populations vary, Some of the variation among individuals can be passed to offspring, Populations of organisms produce more offspring than will survive, Survival and reproduction are not random.
The scientific name for a lion is Panthera Leo. Which part of the name is the species and which is the Genus?
Genus: Panthera. Species: Leo.
What is the definition for "all the organisms of the same group in a particular area"?
Population
This pattern of selection moves in one direction.
Directional Selection
Acquired Immunity
Selection created by human choice is called _____. (Ex: Puppy Breeders)
Artificial Selection
Why are hybrids an unsustainable new species?
Hybrids cannot breed. They have almost 0 fitness and will not be survived by generations.
This type of research is an evaluation or a commentary of another research.
Secondary Source
What makes any individual organism evolutionarily successful?
If it can successfully reproduce and continue the generational line.
The process of a cell engulfing foreign material.
Phagocytosis
A misconception about natural selection is that it can result in perfection. Why is this not true?
Nothing is perfect. There are tradeoffs between traits. Perfection would create an imbalance in an environment.
In an area with high UV exposure, will lighter skin tones or darker skin tones have higher fitness? Why?
Darker skin tones, because of high vitamin D and folate content.
A scientist is looking at the effect of fertilizer on plant growth. The scientist has two plants: one that is given water and sunlight, and one that is given water, sunlight, and fertilizer. What is the independent variable and the dependent variable?
What is the fertilizer as the independent variable and growth of plants as the dependent variable?
What are the two key aspects to the Evolution theory?
1. Modern animals, plants, etc. living things are related.
2. Living things, through a process, have been diverging from a common ancestor since life originated.
Which line of defense is specific immunity to specific foreign material?
The third line.
In the Appalachian mountains there is a high population of bats and a high population of red tailed hawks. They look similar, but are not the same species. What is this concept called?
Convergent Evolution
This type of reproductive isolation prevents fertilization.
Prefertilization
