1. Compared the human cells resulting from mitosis, human cells resulting from meiosis would have twice as many chromosomes the same number of chromosomes one-half the number of chromosomes one-quarter the number of chromosomes

4. The diagram below represents a. budding b. sporulation c. binary fission d. regeneration

7. There are 3 types of polar bears: one with thick coats, one with thin coats and one with medium coats. It is fall, soon to be winter. The temperature is dropping rapidly and the bears must remain warm or they will freeze to death. Many of the bears have approximately 2 cubs (baby bears) each but due to extreme temperatures, many mothers only have 1 cub left. Favorable adaptation Unfavorable Adaptation If speciation were to occur, which adaptation would the species have? Thick coats Thin coats Thick and medium coats

Identify The parts to Darwin’s Theory of Natural Selection. Differences among the organisms within a species exists. A species produces more offspring than can actually survive. Organisms will struggle with each other for limited resources. Overtime, a species can evolve into different species. Organisms that are most fit will survive, reproduce and pass on the trait to offspring. variation overproduction competition speciation Survival of the Fittest

The diagram above shows a series of bone structures in four different species of vertebrates. Explain how these structures support the theory of organic evolution. The similarity in structure suggests that maybe these organisms evolved from a common ancestor.

1. Identify some sources of variation. Let’s summarize… 1. Identify some sources of variation. 2. Identify the theory in which there is no evolution for a long period of time followed by brief periods of change. Punctuated equilibrium 3. Identify TWO THINGS can cause a species to become extinct? No variation within a species Major environmental change the species cannot adapt to Sexual repro, genetic engineering, selective breeding, mutations, migration

4. Why are there large populations of bacteria now resistant to antibiotics? A random mutation results in a small # of bacteria being resistant. They survive, reproduce and pass on the resistance to their offspring. Bacteria reproduce at a very fast rate leading to a large population of resistant bacteria in a short amount of time.

TOPIC: Plants Aim: Explain the process of photosynthesis. Do Now: Take out your photosynthesis reading notes. HW: Natural Selection Lab due tomorrow. Castle Learning Evolution due Tuesday, May 23rd

1. Identify the common ancestor. Species A 2. Identify species that have become extinct. Species C, D, H, L, O, P 3. Identify the species that have not become extinct. Species J, K and M

Which statement could best be inferred from the information in this diagram? (1) Evolution does not involve gradual change. (2) Evolutionary changes can result in extinction. (3) Evolution begins with plants. (4) Evolution produces organisms that all fill the same niche.

Which population of organisms would be in greatest danger of becoming extinct? A population of organisms having few variations living in a unchanging environment. A population of organisms having few variations living in an changing environment. A population of organisms having many variations living in a unchanging environment. A population of organisms having many variations living in an changing environment.

The Florida panther, a member of the cat family, has a population of fewer than 100 individuals and has limited genetic variation. What inference can be made according to the information given? If the environment changes and the panthers no longer have a favorable adaptation, they could extinct.

“Evolution is the result of long periods of stability interrupted by geologically brief periods of significant change.” This concept is called: gradualism natural selection geographic isolation punctuated equilibrium

“Evolution is the result of slow and continuous change over time.” This concept is called: gradulism natural selection geographic isolation punctuated equilibrium

Which concept is not a part of the theory of evolution? (1) Present-day species developed from earlier species. (2) Some species die out when environmental changes occur. (3) Complex organisms develop from simple organisms over time. (4) Change occurs according to the needs of an individual organism to survive.
