Pedigree Charts. Hemophilia, disease in which the blood lacks a clotting factor, is caused by an X linked recessive gene. Joe doe not have hemophilia and Lucille is heterozygous for the condition.  What is the chance that their MALE child will have hemophilia? (Note: you are calculating the probability for their MALE children only, in other words if they have 1 male child, what is the probability that he will be born with the disease?)

In humans, having facial dimples is dominant to not having facial dimples. Mary has dimples, yet only 3 of her 10 children have dimples.  What must Mary’s genotype be?

-homozygous dominant

-heterozygous

-homozygous recessive

-has dimples

-does not have dimples

 

Red-green color blindness is an X-linked recessive disorder.  If Allison is heterozygous (a carrier), and her husband, Michael, is NOT colorblind. What is the chance that their male children will be colorblind? (Note: you are calculating the probability for their MALE children only, in other words if they have 1 male child, what is the probability that he will be born with the disease?)

Section 2: Interconnectedness Of Life Discussion

/in /by

Section 2: Interconnectedness Of Life Discussion. This discussion presents you with some real-life examples of the effects of human impacts, such as hunting/fishing, and global warming. Begin by going through two articles found in D2L under Section 2.

Article 1: Decline of Predators. 

Article 2: How ocean warming and acidification affect food webs. 

    Step one: Make a food chain 
  1.  Article one gives several examples of food chains that were damaged by humans. Choose any one food chain and write it out. Identify the trophic level of at least three steps in the food chain. You are encouraged to use the Internet to investigate further if you’d like more information about a food chain of interest to you.
   Step Two: Interconnectedness – In approximately one paragraph, respond to the following discussion prompts. Relate your discussion points to the articles you read. 
  1. After going through both articles, react to the statement “Life on this planet is a delicate balance”. What does this mean to you?
  2. In what ways have humans directly or indirectly affected this balance?
  3. What measures would you be willing to take to correct human impacts on global food webs?

Identify An Organism That Lives Within 50 Miles Of Your Home.

/in /by

Identify An Organism That Lives Within 50 Miles Of Your Home.. Identify an organism that lives within 50 miles of your home.

Locate a diagram of that organism that has the main organs and structures labeled. Be sure to properly cite your diagram and pictures.

Write a 1,050- to 1,400-word paper on this topic.

  • Briefly describe the environment (temperature, landscape, food sources, etc.) and describe the organism’s role in the environment.
  • Identify the structures and functions of the main organs found in your selected organism.
  • Explain how the organism in the diagram has evolved physiologically to become suited to its environment.
  • If the organism were to be transplanted to a significantly different environment, how would things change?
    • Would their organ system still be as efficient?  Why or why not?
    • Would the organism survive in this new environment?  Why or why not?

Include the diagram and other appropriate pictures in your paper and make sure to provide a full reference for the images in your reference section.

Format your paper consistent with APA guidelines including references and in-text citations. Your paper should include a well-written introduction and conclusion. Use only academic research sources.

1. What is the annual rate of tropical rain forest loss, as a percentage of total forest area, in each of the five countries? Answer by filling in the blank column in the table.

2. What is the annual rate of tropical deforestation collectively in all of the countries represented in the table?

3. According to the table, and assuming the rates of deforestation remain constant, which country’s tropical rain forest will be completely destroyed first?

4. Assuming the rate of deforestation in country C remains constant, how many years will it take for all of its tropical rain forests to be destroyed?

5. Assuming that a hectare (1.0 hectare = 0.01 square kilometer) of tropical rain forest absorbs 0.85 metric tons (1 metric ton = 2,200 pounds) of carbon dioxide per year, what would be the total annual growth in the carbon footprint (carbon emitted but not absorbed by vegetation because of deforestation) in metric tons of carbon dioxide per year for each of the five countries in the table?
