1- In two paragraphs list and describe the major steps involved in photosynthesis.

http://ed.ted.com/on/Hpqpcgn9

1- The Calvin cycle is the second part of the photosynthesis reaction. Photosynthesis stores energy from the sun and carbon from the air together in the high-energy molecule, glucose. Like any factory the Calvin cycle needs energy to create glucose. Where does this energy come from?
2- Rubisco makes up about 15% of the total protein in a chloroplast. Why might chloroplasts have evolved to have so much of this one enzyme?
3- In addition to being highly abundant in chloroplasts, Rubisco is the most abundant enzyme on the planet. Why is Rubisco the most abundant enzyme and why is this important?
4- Temperature and light intensity are two factors that affect the rate of photosynthesis. Which of these factors would you expect to have the greatest effect on the rate at which the Calvin cycle proceeds, and why?
5- Many significant areas of our planet are becoming less green and more areas are being built on (desertification, urbanization, industrialization). More and more areas of the planet are losing their capacity to support plant life. What risks are we facing by making our planet less green? And what can we do to help make our planet more green?
http://ed.ted.com/on/3mPgW5dj
1- How do phytochromes work within the plant cell?
2- What is more important when a plant is deciding when to create blooming flowers: the time of day or the season of the year? Why?
3- Circadian rhythms are especially important in the beginning of a plant’s life. Until their phytochromes perceive the presence of light, seed sprouts grow tall and long, and do not produce any green pigment. As soon as they reach light, they begin to produce green pigment and broader leaves. What are the advantages of producing green pigment only after the presence of light?
http://ed.ted.com/on/SLIWfji1
1- Do you eat organic food? Why? or Why not?
2- Have you ever thought about the world through the perspective of a crop or a farmed animal? What conclusions did you come up with?
3- Do some research. What is the most abundant plant on the planet? How did this happen?
http://ed.ted.com/on/c8aTM4Et
1- Humans have cut and frayed the woven tapestry of Earth’s biodiversity. List and describe three ways Humans have negatively impacted biodiversity.
2- Correctly use the following words in a well-written, scientifically correct paragraph. Be sure to clearly distinguish the differences between each of them and how they intertwine! Be sure to provide examples. Species diversity, biological diversity, ecosystem diversity, genetic diversity.
http://ed.ted.com/on/lX2ej6c6
1- Think about your own home or school and identify the sources of “throwaway” plastic. Which of these could be easily eliminated, if any?
2- According to Moore, why is it impossible to obtain certified organic wild-caught fish?

http://ed.ted.com/on/YGOqhnPB

1. Take some time to read and research some great information about vitamins in the dig deeper section and answer this question- Do we need to take vitamin supplements for optimal health or are we wasting money on vitamin pills? In a 2-3 paragraphs explain if and when a person might need a vitamin supplement and when it might be a waste of money or even be harmful to your health.

1. At the bottom of the dig deeper section there is a link to a cool graphic from information is beautiful. Discover the scientific evidence for popular dietary supplements and Describe 5 supplements that might improve your health and vitality.
http://ed.ted.com/on/Y0RNnPVf
1. The American diet is said to be increasingly energy-rich but nutrient-poor. Use the links you find in the Dig Deeper section to type a complete paragraph on how a person can be overweight but undernourished, and how going back to the basics with nutrient dense foods can improve the health of many Americans.

Experiment To Test The Effect Of Compost On The Development Of Root Crops

/in /by

Experiment To Test The Effect Of Compost On The Development Of Root Crops. Biologists designed an experiment to test the effect of compost on the development of root crops. They tested several different crops, including carrots, potatoes, beets, and onions. They grew most of the plants in the greenhouse, but due to space issues, they had to grow some outdoors. They gave all the plants the same amount of compost. They obtained the compost from a local farmer and from the local hardware store. They ran out of the farmer’s compost, so some of the plants received that compost when the seeds were planted and other plants got hardware store compost after the plants had already started growing.

RESULTS: Some of the roots seemed really big. Other roots seemed normal or small.

CONCLUSION: They couldn’t tell what the effect of the compost was because the results were inconsistent.

 

what is the dependent variable and independent variable in this experiment?

Genetic (Karyotype) Assignment

/in /by

Genetic (Karyotype) Assignment.

I have a genetic assignment due by 11pm today EST. please if you can not deliver do not attempt. Attached here is everything you need. PLEASE Follow guideline before you begin. As you will notice, I started doing the assignment.

BIOL209: General Genetics Laboratory

Examining Human Chromosome Disorders

 

PRE-LAB ASSIGNMENT:

Students are expected to read all pages before coming to the lab to complete the experiments.

Print this entire lab packet and bring it to the laboratory.

Objectives:

After completing this laboratory assignment, students will be able to:

1. Distinguish between the ways to identify chromosomal abnormalities

2. Detect chromosomal abnormalities in a karyotype

 

Introduction:

Karyotyping is the process of pairing and ordering all the chromosomes of an organism, thus providing a genome-wide snapshot of an individual’s chromosomes. Karyotypes are prepared using standardized staining procedures that reveal characteristic structural features for each chromosome. Clinical cytogeneticists analyze human karyotypes to detect gross genetic changes—anomalies involving several megabases or more of DNA. Karyotypes can reveal changes in chromosome number associated with aneuploid conditions, such as trisomy 21 (Down syndrome). Careful analysis of karyotypes can also reveal more subtle structural changes, such as chromosomal deletions, duplications, translocations, or inversions. In fact, as medical genetics becomes increasingly integrated with clinical medicine, karyotypes are becoming a source of diagnostic information for specific birth defects, genetic disorders, and even cancers. Adapted from: https://www.nature.com/scitable/topicpage/karyotyping-for-chromosomal-abnormalities-298

 

Experimental Overview:

You and your partner will take on the role of cytogeneticists working in a hospital. Three case studies will be given to you one at a time for review, along with a set of patient chromosomes. You and your partner will arrange the chromosomes into a completed karyotype on a prepared board. After you have successfully constructed the karyotype, you will analyze it and diagnose each patient. Your patient may have a chromosomal abnormalities or a normal karyotype. Be careful and use your observational skills—things are not always as simple as they seem (especially Case K).

 

Protocol:

1. Obtain a Chromoscan board containing a case study and set of patient chromosomes. Each case study has a Case ID Letter and a unique color. Confirm that the chromosomes match the board.

2. Read the case study found on the left side of the board.

3. On the Cytogenetics Report, record the patient information, including name, case ID, reason for referral, patient age, and source of the cells.

4. To make the process of the karyotype assembly less complex, one of each of the homologous chromosomes is already illustrated on the board. Identify the other homolog and place it on the board in the proper position.

5. Once the karyotype is completed, analyze it for chromosomal anomalies, paying particular attention to chromosome number and structure.

6. Record chromosome number, gender, and chromosomal findings on the Cytogenetics Report.

7. Use the internet to determine the diagnosis of the patient.

8. Return the ALL the chromosome decals to the cryostorage region of the Chromoscan board in RANDOM ORDER, to prepare the board for the next group’s use.

9. Obtain another board and complete the same steps until you have completed a total of 3 case studies.

Instructions for the lab report:

· Assume the role of a Cytogenetist, write out a daily report for the work you accomplished today. It should include but is not limited to:

· A description of how an actual karyotype is constructed. It should be detailed enough that someone else can use your protocol to construct a karyotype.

· DO NOT write the protocol that you followed for this lab.

· Include the three cytogenetic reports that you completed today.

 

· Assume the role of a Genetic Counselor

· Choose one of the case studies with an abnormal diagnosis and research it in further detail.

· Create notes for the patient and/or the patient’s caregiver with additional implications of the diagnosis, including life expectancy, complications, available treatments, support group information, etc.

· Do not forget to include in-text citations and a “Works Cited” or References page.
