1.1 What are the most important variables for controlling ion release rates in “SmartCap Technology”? (1 paragraph)

1.2 What are the essential factors that are important to gain good phosphoric acid etch that will lead to micromechanical retention of the sealant. (Mention 2 points)

What came first? Describe the two hypotheses on the emergence of agriculture. Which one is supported by the archaeological evidence?

Biochemistry:

The carbohydrates of mammalian tissues include     , while the carbohydrates of bacteria include     .

How do phagocytes eliminate pathogens? What group of pathogens are most easily phagocytosed and why?

In order to clone a DNA gene, it is inserted into a larger vector. Why should the vector used be larger?

LOUIS PASTEUR and ROBERT KOCH

Briefly describe the experiments that each person performed to demonstrate the relationship between the arthropod and the disease agent.

1. Brown algae have a stem, holdfast and blade. How does this compare to land plants?

2. Algae you examined were a variety of colors, yet all contain chlorophyll. How can this be?

3. What adaptations do algae have which allow them to be so successful in marine environments?

4. How are cyanobacteria different than algae? How are they similar?

a.) Why do cells divide or why do cells need to divide?

b.) The differences in cell division process(es) between prokaryotic and eukaryotic organisms.

Be sure to provide details of the differences in a logical manner.

1. What is the ultimate reason that a health professional or scientist would be looking to see if a bacterial infection was gram negative or gram positive? Explain your answer.

2. Why might an antibiotic work better for some bacteria species than others? Be specific.

3. What are nitrogen fixing bacteria? Hint: Describe them, where they are located, what they do, and why they are important ecologically.

4. Do Cyanobacteria have chloroplasts? Why or why not?

1)A black guinea pig crossed with an albino guinea pig produced twelve black offspring. When the albino was crossed with a second black guinea pig, six blacks and six albinos were obtained. What is the best explanation for this genetic situation?

A)Albino is recessive; and the second black guinea pig was homozygous dominant

B)Albino is co-dominant; and the second black guinea pig was heterozygous

C)Albino is recessive; and the second black guinea pig was heterozygous

D)Albino and black are codominant.

2)Which of the following processes would best help explain independent assortment?

A)the fact that any pair of chromatids in a tetrad can cross over

B)the random arrangement of chromosomes at metaphase I

c)the separation of chromatids at anaphase II

D)the random arrangement of gene loci on a chromosome

E)the random arrangement of chromosomes at metaphase II

Explain in detail why incubation time affects solubility. It has also been shown that the reaction of whey protein with polysaccharides can improve solubility at pH 4.5. Why is this particularly important for beverages?

Which most effectively describes the relationship between carrier and channel proteins?

(Select all that apply.)

A) Carrier proteins are passive transport mechanisms, but channel proteins can be either active or passive.

B) Carrier proteins are active transport mechanisms, but channel proteins can be either active or passive.

C) Channel proteins are active transport mechanisms, but carrier proteins can be either active or passive.

D) Channel proteins are passive transport mechanisms, but carrier proteins can be either active or passive.
