For your primary post, select ONE of the following discussion topics. Please select only one of the three topics listed. Using your own words, write a primary post of at least 125 words that follows the instructions. Be sure to address everything listed in the instructions. Each topic has two subtopics [a, b]; please address both of them.
Your primary post is worth up to 14 points. Also, make a substantive reply to a fellow classmate on any topic. Use your own words. You don’t need to use any sources other than the ones specified, but if you do use other sources, you must cite them.
Topic 1. Climate Change / Terrestrial Species. Watch the 7.5 minute video by Jim Cox (1)* about how climate change affects the “species range” of terrestrial species. This video can be found in the “Instructor Insights” of Week 1. Based on the video, address the following:
Topic 2. Evo-devo. Watch the video (2)* featuring Sean Carroll discussing the science of evolution and the field of evolutionary-developmental biology (evo-devo).
Topic 3. The cusp of a revolution in medicine. In a recent op-ed, Craig Venter (3)* shares his opinion that we are “on the cusp of a revolution” in medicine. Venter also addresses the issue of human germline editing, which is something we discuss in a later part of this course. For now, let me just note that editing the human germline means making permanent changes to the DNA of eggs, sperm, or a fertilized ova. Such changes would be permanent and would be passed on to future generations.

Biochemistry & Structure of Living Cells.
Select one of the following discussion topics for your primary post, which should address the discussion question in your own words. Your primary post should be at least 125 words. Also, please respond to a fellow student on any topic.

Topic 2. Characteristics of ATP. If you choose this topic for your primary post, you must base your post on the instructor’s video about ATP (2)*. The video can be found in the Instructor Insights area.
Topic 3. Chemosynthesis in the Giant Tubeworm. The Giant Tubeworm (Riftia pachyptila) is an animal that lives on the floor of the ocean, near hydrothermal vents that release very hot, chemical-rich water. The adult form of the tubeworm is sessile, which means that it plants itself in one place, and doesn’t have any locomotion. Riftia pachyptila has a unique way of getting the energy that it needs to stay alive (3)* (4)* (5)*.

Week 4 Discussion: Genome, Transcriptome and Proteome.
For your primary post, please respond to one of the following three with a post of at least 125 words addressing each point given in the instructions. Also, please reply to at least one fellow student on any topic.
Note: If you choose this discussion topic, your answer must be based on the material specifically covered in the video, rather than generic information on –omics from the internet. If you would rather research information from the internet, then choose discussion Topic 3.
Note: the rulings of lower courts are NOT of interest for our purposes. Please concentrate only on SCOTUS’s ruling. The objective here is to emphasize the precedent-setting ruling of the highest court (SCOTUS), rather than to recount the litigation history.
Choose one of the following three topics for your primary post. Your primary post should address everything that the instructions call for (for the topic you choose). Your post should also be at least 125 words in length. Additionally, please respond to at least one other discussant on any topic.
Topic 1. Sexual Reproduction in Unicellular Eukaryotes. Watch the instructor’s video about “Sexual Reproduction in Unicellular Eukaryotes” (1)* which can be found in the Instructor Insights section for this week. For a single-celled species to be capable of sexual reproduction, the species must have both haploid and diploid forms
Topic 2. Apoptosis. Watch the Khan Academy video about apoptosis (2)*, then address the following issues in your own words:
Topic 3. Tumor-suppressor genes versus Proto-oncogenes. This is a library-research topic in which you are required to provide your sources. Mutations in tumor suppressor genes can contribute to or cause cancer, just as mutations in proto-oncogenes can also contribute to or cause cancer. However, tumor suppressor genes are very different from proto-oncogenes.

Discussion
Topic 1. Pedigree for Trait 1. Suppose that we are certain that Trait 1 follows a Mendelian pattern of inheritance and that Trait 1 is an autosomal dominant trait. Suppose further that the dominant allele is designated as A and the recessive allele is a.
Topic 2. Pedigrees for Trait 2. Suppose that we are certain that Trait 2 follows a Mendelian pattern of inheritance and that Trait 2 is an autosomal recessive trait. Suppose further that the the dominant allele is B and the recessive allele is b.
Topic 3. Esvelt’s Regret. In the article by Zimmer (1), Kevin Esvelt says that he made a huge mistake by championing the application of a technology that he now says is far too dangerous to actually deploy. In a post of about 125 words, address the following:
Topic 4. Societal Aspects of Human Gene Editing. Read the article by Neuhaus (2) and/or the article by Ossola, then address the following:
