Create a 7- to 10-slide Microsoft® PowerPoint® presentation about your chosen species.

Include the following in your presentation:

·  How may your species have evolved? 
 

·  Describe the mechanism of speciation, in general, and apply the mechanism to the species you researched. 

·  Include evidence that supports your speciation hypothesis.

·  What role does natural selection play with this species? What role does it play with evolution in general? Does that apply to this species?

SCI 230 Week 7 Physiology Assignment

 

Locate a diagram of the internal anatomy of an organism with the main organs and structures labeled.

Write a 350- to 700-word paper explaining how the organism in the diagram has evolved physiologically to become suited to its environment.

Reference the diagram in your paper.

Format your paper consistent with APA guidelines.

 

SCI 230 Week 9 Assignment Food Web Diagram

 

Create a diagram in which you illustrate the energy flow among organisms of a food chain in a particular ecosystem.

Select an ecosystem, such as a temperate forest, desert biome, or the Everglades.

Determine the interdependency of life in your ecosystem by examining its organisms.

Include the following:

·  List the organisms that can be found in your ecosystem. What is the benefit of this biodiversity?

·  Label major organisms that live in your selected ecosystem: P for producers, C for consumers, and D for decomposers.

Write a summary of your food chain that:

·  Describes the major categories of organisms: producers, consumers, and decomposers.

·  Describes the interactions between organisms in your ecosystem.

·  Evaluates potential hazards caused by humans that might affect your ecosystem’s stability, such as environmental pollution. What effect does this hazard have on the biodiversity in your ecosystem?

·  Lists the abiotic factors present in your ecosystem.

·  Describes the food chains associated with your ecosystem. Address the following items:

o  Name of the plant or animal

o  What it eats

o  What eats it

How it has adapted to the ecosystem 

 

SCI 230 Week 9 Assignment Human Population Growth

 

Write a total of 150- to 300-words in  response to the following:

·  Explain the two types of population growth.

Analyze the type of growth exhibited by the human population and its effect on the environment. 

 

Discussion Questions

Week 2

DQ 1

Why is it important to differentiate between eukaryotic and prokaryotic cells? What do you think is the biggest difference between the two?

 

DQ 2

Discussion Question 2

For the cell process assigned (mitosis, meiosis, photosynthesis or cell respiration), answer the following:

1)    What is the purpose of the cell process?

2)    What would happen to the cell and the organism if the process stopped occurring?

3)    Can you think of another way the cell could achieve this process?

 

1.    Brian- Mitosis

2.    Carla - Mitosis

3.    Christina- Mitosis

4.    Crystal-Mitosis

5.    Crystalin  - Meiosis

6.    Eric– Meiosis

7.    Geneve- Meiosis

8.    Jason – Meiosis

9.    Javier-Photosynthesis

10.Jessica-Photosynthesis

11.Joliene–Photosynthesis

12.Jon’na Means – Photosynthesis

13.Michael -Mitosis

14.Michael N. – Meiosis

15.Maria– Mitosis

16.Rebekah – Meiosis

17.Sharetta - Photosynthesis

18.Siegel -Mitosis

 

 

Week 4

DQ 1

Discussion Question 1

 

Select two of Mendel’s four hypotheses that are described in Ch. 9 of Campbell Essential Biology With Physiology. How could you rewrite these in your own words? Find an example that illustrates the hypotheses. 

DQ 2

Discussion Question 2

 

·         Choose a trait or disorder controlled by one gene. Briefly describe the trait and identify whether it is inherited as a dominant, recessive, or sex-linked trait. What would a pedigree of this trait look like?

 

Week 6

DQ 1

Discussion Question 1

 

·         Review the “Natural Selection” section in Ch. 13 of Campbell Essential Biology With Physiology. Organisms have evolved physiologically and anatomically to adapt to their environment. Select one species from the text or another source. How have their traits evolved by natural selection to maximize their ability to maintain homeostasis and equilibrium?

 

 

 

DQ 2

 

Discussion Question 2

 

What are two examples of evidence that support the theory of evolution by natural selection? One example should relate to the anatomy or physiology of animals. Locate a website that discusses the evolution of a new species. Do you agree this is a new species, or is it diversity within the same species? Explain your answer.

 

Week 8 

DQ 1

Describe your local ecosystem or an ecosystem that is important to you, including its hierarchy of interactions and its biodiversity. How is the ecosystem dependent on the biodiversity? Explain one threat to that biodiversity.

 

DQ 2

Are all threats to biodiversity caused by humans?
