What does it mean to say that a hypothesis is testable and can be falsified? Give an example of an untestable or an unfalsifiable hypothesis.

In Week 2, we saw how cells of similar size, shape, and function form tissues. As a tissue, muscle is very diverse. Let's kick off our study of muscles by discussing the subtypes of muscle tissue, beginning with smooth muscle. Where do we find this muscle tissue, how does it contract, and what are its defining characteristics? In what ways are smooth muscles working in your body right now?

Here's the muscle discussion! I bet you will learn something new about muscles this week. First we will tackle smooth muscles. Where are they? How do they work? What do they do?

Do energy and nutrients (matter) behave similarly as they move through an ecosystem? Explain.

Imagine that you took the mass of dried soil before you added water to it. You then added water and waited a week. Then you dried out the soil again. Would you expect the mass to be higher, lower, or equal to your original measurement? Explain your answer.

Explain in your own words the difference between a scientific journal, a science magazine, and a website.

(1). Discuss how proteins can fold rapidly and reliably to their native conformation and how misfolded proteins can lead to diseases.

(2). What are the differences of saturated, polyunsaturated and monounsaturated fats? How do they affect human health.

(3). What are the differences of cellulose, starch and glycogen? Which one is the most abundant organic compound on earth?

(4). What are the differences between DNA and RNA? What is the chemical mechanism of complementary base pairing?

what antimicrobial agent is most commenly used to treat Streptococcus Pyogenes (strep throat) infections?

In what population(s) do(es) Staphylococcus aureus cause infections? What types of infections are associated with S. aureus? How does Protein A contribute to the virulence of S. aureus? What toxin causes toxic shock syndrome? What type of toxin is associated with scalded skin syndrome? What toxins are involved in staphylococcal food poisoning? In what clinical condition would coagulase-negative staphylococci be significant? Which coagulase-negative staphylococci are considered more significant, and might need to be identified to the species level? What are the two types of coagulase produced by S. aureus, and how is each type detected in the clinical lab?

Cystic fibrosis (CF) is a genetic disorder that affects mostly the lungs, but also the pancreas, liver, kidneys, and intestine. CF is inherited in an autosomal recessive manner with simple Mendelian inheritance. It is caused by the presence of mutations in the gene for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. A normal couple intends to have children but consult a genetic counselor because the man has a sister with CF and the woman has a brother with CF. There are no other known cases in their family. They want to know: (1) What is the probability that their first child would be normal? (2) What is the probability that their first two children would have CF? (3) If they would like to have five children, what is the probability that at least two of them would be normal?

6. Compare and contrast the function and structure of the uterine stratum basalis and functionalis.

1.What is the name for the covalent bonds that create the Nucleic Acid backbone?

2.Define Complementarity as it is used in nucleic acid base pairing and explain how complimentary base pairing is the basis for making faithful copies of DNA from DNA templates and RNA from DNA templates.
