Lab Report - Investigating Mold Growth
Create a table to record your observations. You MUST include your data table with your observations when you submit Project 1 to receive full credit.
1. Percent mold coverage when comparing salted and unsalted bread over a 10 day period.
2. Which slice grew more mold?
3. How did the salt affect the mold growth?
4. Analyze how and why the salt affected the growth of the mold. Identify other factors which may have played a part in the growth of the mold and explain their roles.
Lab Report - Comparing Flowers
Follow the directions given on page 681 of your textbook to complete this Biolab to compare monocot and eudicot flowers.
Monocot and eudicot flowers are classified depending on the structure of their seeds. Monocots usually have flower petals in multiples of 3 or 6, parallel veins in their leaves, vascular bundles scattered throughout their stems and fibrous (bushy) roots. Eudicots usually have flower petals in multiples of 4 or 5, netted veins in their leaves, vascular bundles on the perimeter of their stems, and thick taproots.
Follow the directions in the lab, choosing at least 6 different varieties of flowers and at least three different features to observe and compare; then answer the following questions.
1. Record your data in the table below.
2. Draw and label the female and male reproductive structures and other flower parts of one of your monocot flowers.
3. Draw and label the female and male reproductive structures and other flower parts of one of your eudicot flowers.
4. Which of the flowers that you examined were monocots and which were eudicots?
Project -
Part A - Fact, Fiction, and Controversy in Biology
Choose one of the following two options for Part A of this project. Your report can be in one of the following formats:
1. a minimum 500 word essay,
2. a 2-3 page informational handout or brochure,
3. a multipage, multimedia website, or
4. some other format that you feel adequately covers all the project requirements, and that can be submitted using the tools available to you.
Bird Flu: In China in 1996, a human was infected with a strain of avian flu called H5N1. In the subsequent 12 years, 400 infections worldwide resulted in approximately 100 deaths, spread out over 9 countries. The media have been unrelenting in their coverage of this disease and its potential role in a global disease outbreak. Research this disease and evaluate whether it is a case of legitimate cause for panic or a case of misinformation and worst-case scenarios. (It's possible that it could be a little of both!)
Your report should include the following:
- What virus is responsible?
- What is the link with flu and Asia?
- What is the primary means of transmission to humans?
- What is the mortality rate of this disease?
- What would need to happen for this disease to pose a significant global threat (think in terms of transmission)?
- Does this virus replicate by the lytic or lysogenic cycle? Describe that process.
- How does your body respond to infection by a virus?
- What can be done medically for a person infected with a virus?
- How is flu vaccine manufactured?
- Terms to include and define in your report are: pandemic, mortality, transmission, zoonosis, disease reservoir, pathogen, antibodies, antigen, and antiviral. (1 pt for each term that is included and 1 pt for each term that is defined)
- Be sure to include in your conclusion your opinion, based on stated facts, on what is the real scope of the threat posed by this virus. Are we doing enough? Not enough? Too much? (5 pts)
You may use the resources available to you to complete this project. You are encouraged to do at least some of your research online, and to make sure that you have the most up-to-date statistics.
GMO's: (Genetically modified organisms) are organisms that have had their DNA artificially altered, often by the addition of one or more genes from other organisms. Many food crops have been genetically modified; modification of others is pending. GMO's are a source of controversy because proponents see them as the way to improve nutrition, disease and drought resistance; increase crop yields; and have a positive effect on the economies of developing nations. Opponents believe such organisms can compromise other genetic stock, produce new allergens, and have a negative effect on the economies of developing nations. Research genetically modified food plants and evaluates the pros and cons of their development and use in food products.
Your report should include the following:
- What GMO food plants are currently planted in your country?
- What genetic modifications have been made to the above listed plants?
- Describe, in detail, the process of creating a GMO plant.
- Why aren't foods made with GMO products required to be labeled as such?
- Why have GMO food crops been an issue within the WTO?
- What demonstrated benefits have been observed in GMO food crops?
- What demonstrated problems have been observed in GMO food crops?
- Using your knowledge of plant reproduction, research what type of pollination strategies are practiced by the food crops that currently include GMO varieties. How might the pollination strategy increase or decrease the likelihood of genetic contamination of nearby, non-GMO plants?
- Explain the controversy over patenting life forms and summarize the legal issues that have ensued.
- What regulations exist for planting and selling GMO food crops, and for including them in human food?
- Terms to include and define in your report are: transgenic, intraspecies gene transfer, interspecies gene transfer, cross pollination, terminator technology, and patent. (1 pt for each term that is included and 1 pt for each term that is defined)
- Be sure to include in your conclusion your opinion, based on stated facts, on the advisability of continuing to use/expanding on this technology.
