Any change in behavior or appearance that increases survival

How often you pass on your genes, or reproduce

All the possible genes within a population

Variation of a gene; example: brown eyes

The movement of genes into or out of a population; example: migration

A random chance event that shrinks the population; example: forest fire

The differences, or variety, in DNA within a population

Any change, good or bad, in DNA

Mating with individuals based on appearance or convenience of location

Lions live in the south Sahara Desert in breeding groups called prides. Females tend to stay in their pride, but males may leave to join another pride. When males leave to join another pride, what mechanism of evolution is being demonstrated?

A population of red, yellow and pink rose bushes grew in a local nursery. A tornado damaged the nursey and rose bushes. The nursery staff saved what they could. 6 months after the clean-up effort the nursey started to only selling pink and red roses because the yellow ones no longer grew there. What mechanism of evolution is being demonstrated? 

New Caney is an area in Texas that typically has a warm climate. Rabbit populations that live in the New Caney forests are typically brown and gray. A random change in the DNA caused some rabbits to have white fur. After 3 years, the gene frequency for white rabbits has not increased, but you will still see a white fur rabbit from time to time in the forest. What mechanism is this an example of? 

A lake in kingwood is divided into two sections, a fast moving small channel and a large slow moving deep pond. There are two species of guppies that live in this lake. Round tailed guppies have a high frequency in the pond area and pointed tailed guppies have a high frequency in the channel. Pointed tailed guppies are known to be stronger, faster swimmers. Every year a population sample is taken of the two guppies and the frequency of alleles doesn't really change between the two areas. Females seem to mate with males that live in the same area they do, and continue to pass on the allele best suited for their part of the lake. Which mechanism is being demonstrated? 

10 species of birds were being transported on a boat to another country. Two of the cages were accidentally left open and the birds escaped. The two species of birds that escaped landed on a deserted island. The birds lived off insects and vegetation and continued to grow their populations. After two years both bird species have established a heavy population on the island. What evolutionary effect has taken place? 

In a forest there were 6 species of trees. A forest fire occurred and only 1 species survived. As the forest repopulated only this 1 species grew and increased in frequency. When genetic drift occurs and shrinks the population in a drastic way, what is this an example of?

True or False: Natural selection occurs due to random events. 

A lion forelimb, a bird wing and a human arm have similar bone structures in their forelimbs. They all have humerus bones. Which MOST likely describes why the body structures of these animals are so similar?

Ol Donyo Lengai in Tanzania is one of Africa's most active volcanoes, and on it's northern flank is Lake Natron. This is one of the world's most toxic bodies of water, yet home to two species of flamingoes, Phoenicoparrus minor and the more abundant Phoenicopterus roseus. The two species do not interbreed even when they reside very close to each other. Which evolutionary process fails to occur?

Gradual change in a species can result in ____. 

Viruses need the cell of a host organism in order to reproduce. In one viral reproductive strategy, the virus will inject its DNA molecule directly into the host cell’s chromosome. The organism will then copy the viral DNA along with its own, creating many copies of the viral DNA. This is how diseases like HIV and Chickenpox stay in an individual’s body forever. What is this reproductive cycle called?

Which portion of the virus do antibodies attack to prevent the virus from attaching to a host cell? 

Which of the following would be the correct order of the taxonomic categories from Most inclusive to Least inclusive?

Which of the following is NOT a characteristic of protista?

Which of the following could be an organism that is eukaryotic, has a cell wall, and is heterotrophic?

Which of the following is most CLOSELY related to Homo sapien?

Which portion of the virus is known as the capsid?

Amphiprion percula is the scientific name for clown fish. Which portion of the name is the genus?

Which of the following characteristics could be used to distinguish between the kingdoms Archaebacteria and Eubacteria? 

Which viral life cycle is pictured above? 

Which of the following organisms below would not have lungs?

Based on the characteristics above, which of the following would correctly label column B? 

Viruses are specific to the cells they infect due to the specific protein spikes.

Which of the following is NOT a characteristic of Animalia?
