Transport of glucose into epithelial cells lining your small intestine is dependent on a pre-existing electrochemical gradient of sodium (Na⁺) ions across the apical plasma membrane. If that gradient is eliminated, glucose transport stops. This is one example of ____________________.

In human beings, the gene for red green colorblindness (r) is sex linked and recessive to its allele for normal vision (R), while the gene for freckles (F) is autosomal and dominant over its allele for nonfreckled (f). A nonfreckled, normal visioned woman whose father was freckled and colorblind, marries a freckled, colorblind man whose mother was nonfreckled.

a. What is the genotype of the woman's father? b. What is the probability that the couple's first child will be a non-freckled, normal visioned girl c. What is the probability that the first two children born to the couple will be freckled and colorblind girls? d. What is the probability that the first child born to the couple will either be a freckled, colorblind boy or a non freckled, normal visioned girl or a non-freckled, normal visioned boy e. What is the probability that the first four children born to the couple will be freckled and normal visioned girls?

Examine the example of the media explosion surrounding the extinction of redheads. What problems does this exemplify in the relationship between science and the media? What are some suggestions you have to mitigate these simplifications and exaggerations of science so that the general public has a better understanding and awareness of scientific reality instead of misinformation?

Cystic fibrosis is an autosomal recessive disease characterized by two copies of a mutated CFTR gene. If one in 100 people in the United States have cystic fibrosis and one in 5.0505050505 people are carriers for cystic fibrosis, calculate the number of individuals that are homozygous dominant. In other words, how many people would have two copies of the normal (non-mutated) CFTR gene. Use the Hardy-Weinberg equation and explain how you determined this. 

How did Watson and Crick's suggestion that nitrogen containing bases in nucleotides pair together in DNA support Chargaff's rule; and allow the double helix to have a constant width (as indicated by Franklin's X-ray crystallography studies?

what enzyme does Rubisco catalyze and why is it important?

What you have to do:

Your task for this activity will be to compare and contrast the locomotor strategies of the following three hominin species: Ardipithecus ramidus, Australopithecus afarensis and Homo erectus. You will accomplish this by answering the following questions.

Use the following resource for Ardipithecus. https://milnepublishing.geneseo.edu/the-history-of-our-tribe-hominini/chapter/ardipithecus-ramidus-ardipithecus-kadabba/ (Click)

Use the following resource for Australopithecus https://milnepublishing.geneseo.edu/the-history-of-our-tribe-hominini/chapter/australopithecus-afarensis/ (Click)

Use the following resource for Homo erectus https://www.nationalgeographic.com/science/2004/11/humans-were-born-to-run-fossil-study-suggests/ (Click)

Before you begin make sure view all relevant reading material so that you can give me informed opinions.

1. Which hominin had the best arboreal capabilities? Make sure you explain your answer by talking about only one feature that backs up your claim. Choose only one feature from the lower extremities (Legs and feet).

2. Which hominin was the first to have feet that are effective for habitual bipedalism? Briefly explain what makes their feet more effective for bipedalism when compared to previous hominins.

3. Which hominin had the best anatomy for running on two legs? Briefly explain how you would know and tell me about two specific skeletal features that suggest that your chosen species was running on two legs.

4. Lastly, I would like you to give a short summary of the notable evolutionary changes in locomotor strategy (the way that you move around) that you notice occur over time as seen from the perspective of Ardipithecus ramidus, Australopithecus afarensis and Homo erectus.

1. If you looked at a drawing of a lipid, how could you tell whether it was saturated or unsaturated?

2. Describe an example of kinetic energy being transformed into potential energy.

3. Describe an example of potential energy being transformed into kinetic energy.

4. What makes something an organic molecule?

5. How can you tell if a solution is a good buffer or not?

8. You don’t have to write this down, but be sure you understand the peacock experiment.

9. What percentage of songbird chicks in a typical nest are fathered by different parents? Why do the female birds risk this? And why do they bother with “monogamy” in the first place?

10. What’s different about the Jacanas?
