Which type of terrestrial biome is San Diego? Describe the factors that have produced the climate and list the types of plants and animals in the area.
Which type of aquatic biomes are found in San Diego and how do you know?
Describe how energy and chemicals cycles through the environment, including the role of producers and all the consumer trophic levels.
What are two different physical or chemical factors that can and will influence life the biosphere? How can these factors affect multiple biomes (think cycles)? Be specific on what the factor is and how it will affect population ecology.
Explain how small natural disturbances (like fire) affect communities and populations using ecological language. Include abiotic and abiotic factors.

Genetic engineering has brought many promising aspects of improvement to the lives of human beings. The conversation has, in the last few years, expanded to the use of genetic engineering for the purpose of conservation biology. Such conversation includes not only what is possible but also what should be done. How should we approach the possibility of modifying genomes and embryos of endangered and even of already extinct plants and animals?
In other words, how much could and should we manipulate the DNA of wild species in our attempt to save them?
Prior to the idea of using genetic engineering, the plan was to move species around (a human-led migration of sorts) according to where they were best suited in light of climate change. But what if genes were manipulated instead, such that these species could stay in their original regions withstanding those changes in — and caused by — climate such as drought, flood, fire, high-category hurricanes, pathogens, and rise in water and air temperature?
One thing that has already been occurring for roughly 20 years is the hybridization of wild species (this has occurred for hundreds of years in agriculture). The inbred population of Florida panthers, for example, received a little genetic help from a Texas sub-species in the early 2000s. The cross-breeding between these two subspecies allowed for the Florida panther to successfully reproduce cubs with higher genetic variation. The idea of hybridization, however, is seen as a very slow and inefficient process in relation to how quickly our world is changing. Wildlife genetic engineering would allow for a much faster adaptation (“facilitated adaptation”), though there are concerns for potential harm in the attempt to do good. For example, genes can have multiple functions. If a gene is imported because of a particular benefit, there is the risk of also importing dangerous traits coded by that same gene.
Do you see the moving of genes from one wild species to another as a violation of nature’s diversity? Or do you see it as a necessary means to save species on the brink of extinction?
Justify your answer.

The toxicological evaluation is designed to provide students with an opportunity

The toxicological evaluation is designed to provide students with an opportunity to do their own risk evaluation of an assigned compound. Each student will be assigned a compound and will assess where or not the compound is poses risk to biological systems (humans, animals, and environment). The assessment should include the following provided the information is available:
Description of the compound (what is it)
Location (where is it found; naturally occurring or synthetic)
Summary of a case study (eg. poisoning, ecological disaster, historical use)
Uses (eg. therapeutic, agricultural)
Toxicodynamic properties (what does it do)
Toxicokinetic properties (ADME)
Mechanism of toxicity (if known)
Sensitive populations
Treatment
Federal Regulations
Reference exposure doses (oral or inhalation;
see EPA, FDA, NIOSH, OSHA)
Your assessment on the potential risk to humans, animals and/or the environment
The assessment should be concise (please no more than 5 pages). All information must be sighted from a peer reviewed source (acceptable sources are listed below in the Recommended Reading Section). Each student will give a brief presentation (chalk talk NO PowerPoint or other media) on the last day of class.

To demonstrate your understanding of your article, write a brief “summary” sheet that answers the following questions:what was the authors’ main question,
what was THE key experiment (or 2 key experiments, if applicable),
what were the key findings from the data and which figure(s) showed these, and
what did this research contribute to the field?
Do not describe every figure here, focus on the most important one(s). Make sure you specifically address each of the components listed above, rather than just write a general summary of the article. This set of questions shows me you understood the main point of your article.

Hi. Please read all instructions in files, this is very important for me and my grade as 20% of the final grade is from this internal assessment. To get familiar with what this is, please do research on google about IB. Please divide the research paper into sections as it is shown in the great example in files!! Also, if you can’t find anything about my example and suggestion as topic for the internal, you can do something a correlation between the thyroid gland with something, as my mom is struggling with thyroid so it shows engagement and interest and i can gain more points for that.
