Traits and Environmental Changes
© Hedgehog Learning
Why did the environmental changes in the early 1900’s in England cause the “gray” peppered moth to decline, but the “black” peppered moth increased in population?Slide3
Traits and Environmental Changes
Genetic trait for skin tone and skin cancer risk
© Hedgehog Learning
People with a genetic trait for fair skin are more likely to get skin cancer during their lifetime.
Fairer-skin humans generally originated further away from the equator than darker-skin humans.
Explain how the environment influenced early human traits for skin tone.Slide4
Dichotomous Keys
Dichotomous keys help us to identify organisms based on their physical characteristics.What is the dichotomous key in the picture used to identify?

Reproduction
Sexual ReproductionRequires male and female
Fewer offspringGreater genetic variationAsexual Reproduction
Requires only one parent
Many offspring
Less genetic variation
What are the advantages of sexual reproduction in fighting off certain illnesses over multiple generations?
© Hedgehog Learning
Some plants can reproduce asexually.
Animals reproduce sexually and produce fewer offspring.Slide7

Parts of a Cell
Looking at the diagram on the right:
Where is the genetic material contained?
Is this cell prokaryotic or eukaryotic?
Is this cell autotrophic or heterotrophic?
Would this cell be found in the animal kingdom?
Nucleus
Eukaryotic
Autotrophic
NoSlide8
Human Interaction with the Oceans
Building artificial reefs to replace those damaged by humans
© Hedgehog Learning
Many coral reefs have been damaged or destroyed by human activity and pollution.
In an effort to restore destroyed reefs, scientists have created artificial reefs like the one in the picture.
What other ways have humans influenced the ocean habitat? Slide9

Would not help avoid predators
Would not help in summertimeSlide10

They would not have as good of a chance at survival.Slide11

The change would happen slowly
They would not find food
Many would starveSlide13
