What are the advantages to using yeast as a model system, in general and/or for cell cycle studies in particular? What are some limitations?

Paper instructions answer the question. There is a 300-word cap on this part; references and question do not count toward this word limit. Posts that demonstrate quality, clarity, depth, ; focus will be more positively evaluated than posts that are shy on these key elements.
Make sure this is graduate level paper.

Which way will the O₂ move ?In reference to the previous question, what process would the cell use to maintain a low concentration  of carbon dioxide?

Use your notes or textbook to answer the following questions.
1. Transport across the cell membrane in which substances move from high concentration to low concentration without the expenditure of energy.

2. Transport across the cell membrane that requires energy to move substances against the concentration gradient.

3. is how small nonpolar substances pass through the selectively permeable cell membrane.

4. is the diffusion of water across a selectively permeable membrane.

Read each transport scenario carefully. Pay close attention to what the question is asking. Pay attention to the definitions above!

5. During respiration oxygen (O₂) passes into cells where it can be used to create cellular energy. Oxygen molecules are small enough to pass through phospholipid bilayers. If the concentration of O₂ is 42% inside the cell and 7% outside the cell. Which way will the O₂ move ?
6. What is this called ?

7. A cell with a normal concentration of 0.9% carbon dioxide is placed in a solution of 4% carbon dioxide. Carbon dioxide molecules are small, so they can diffuse through the membrane. Which way will they diffuse?
8. Carbon dioxide is a waste product that is produced in the production of cellular ATP and needs to be continually removed from cells. In reference to the previous question, what process would the cell use to maintain a low concentration  of carbon dioxide?

9. A cell with a normal concentration of 2% starch is placed in a solution of 28% starch. Starch molecules are too large to diffuse through the cell membrane. Which direction will the water move (into or out)?
10. What is this called (be specific)?

11. Calcium is an essential plant nutrient that plays an important role in the structure of plant cell walls and membranes, calcium also serves as an obligate intracellular messenger. A certain plant cell requires a concentration of 80% calcium, it currently has only 70% calcium. The extracellular fluid contains 30% calcium, will the cell require energy to obtain enough calcium to function? Why?

12. Amoebas are animal-like aquatic protozoan. An amoeba cell that normally lives in freshwater  is placed in saltwater . If osmosis occurs, what will happen to the cell?

13. A Euglena that normally lives in saltwater  is placed in freshwater . If osmosis occurs, what will happen to the cell right away?

14. What will eventually happen to the cell?

15. Algae are plant-like aquatic protists. An algal cell that normally lives in saltwater  is placed in a solution of 0.% salt. If osmosis occurs, what will happen to the cell?

16. What cell feature prevents it from bursting?

17. What will happen to plant cells when providing sufficient water for growth ? What is this called ?

18. Plants require water for photosynthesis. This is what makes them autotrophs . During a drought the soil water concentration is lower than the concentration of water in the root cells of the plant. In which direction will osmosis occur?

19. What happens to the appearance of the plant?
20. What is this called ?

Did you have any idea that the health and diversity of your gut bacteria was so important? What should we do to make use of this kind of information? Will this information make you think differently about the huge responsibility that comes with nurturing the microbes that live in and on you?

Microbiome

How does our Microbiome make us who we are?

Did you have any idea that the health and diversity of your gut bacteria was so important? What should we do to make use of this kind of information? Will this information make you think differently about the huge responsibility that comes with nurturing the microbes that live in and on you?

Is all of this talk about probiotics and gut health a fad, or is this truly the century of the probiotic? What kinds of things do you do to protect your gut?

Explain how the mRNA vaccines work based on your knowledge of the Central Dogma of Molecular Biology. What are some of the diseases that infants and children in the US are routinely vaccinated against?

a) Vaccines. Your friend is worried about the many vaccines that his newborn son is scheduled to receive and asks you for advice since you are taking a biology course. Start with an explanation of how vaccines work.

Briefly contrast the traditional methods used to create vaccines with more recently used biotechnology techniques, including the COVID 19 mRNA vaccines.

Explain how the mRNA vaccines work based on your knowledge of the Central Dogma of Molecular Biology. What are some of the diseases that infants and children in the US are routinely vaccinated against?

How have vaccinations impacted the frequency of these diseases over the past 100 years? Why are some people worried about giving their children vaccines? Why do some people believe that the MRR vaccine can cause autism?

Is there scientific evidence to support these concerns? Conclude with advice to your friend in regard to getting the recommended vaccines based on what you learned from reliable information sources.
b) Personal Genomics. Services like 23andMe and Ancestry have made it possible – even popular – for the average person to obtain in-depth information about their genome, including details like food allergies, drug sensitivities, and disease risks.
