1.How does meiosis differ from mitosis? What is the ploidy number of the products in both processes? The main difference between mitosis and meiosis is that mitosis involves the process in which a diploid cell divides into two identical diploid cells. So, basically, a cell that has two entire copies of an organism’s chromosomes splits into two… Continue reading Week Reflection 3/20-3/23
3 things I learned: There are two kinds of genes that can result in caner. One, oncogenes, speed up the cell cycle, while, two, tumor suppressor genes, are what inhibit a defective cell from continuing on in the cell cycle, and are the “brakes” of the cycle. Oncogenes and tumor supressor genes are spread throughout… Continue reading Weekly Response 3,2,1 (3/6-3/10)
Describe the overall structure of a chloroplast and where the two major steps of photosynthesis take places. Talk about the thylakoid and the stroma. Discuss the light reactions (Photosystems I and II, ATP synthase, the electron transport chain) and the Calvin Cycle.
Compare and contrast anaerobic cellular respiration and aerobic cellular respiration. Address glycolysis, the citric acid cycle, oxidative phosphorylation, lactic acid fermentation, alcohol fermentation, NADH, FADH2, and ATP. Well, first off oxygen is required for oxidative phosphorylation to work properly because without it the electron transport chain does not function. Oxidative phosphorylation produces the most ATP… Continue reading Semester 2- Week 1
We started off this week learning about the signal transduction pathway. The basic gist of the signal transduction pathway is that it starts with a ligand that floats on the outside of the cell. That is the first step to the four step process. The next step, reception, occurs when the ligand bonds perfectly to the receptor protein which is located in the cell membrane. Once the ligand is fitted into the receptor protein, transduction is activated. (Step 3). This all now happens in the cytoplasm. A relay protein was activated during reception, and now activates other relay proteins. The activating of multiple proteins, one after another is called amplification. The fourth step is the response. Below is an image of the signal transduction pathway.
We made it through our first 5 day week! This week, along with the previous week, we have been focusing discussions and activities around Big Idea 1- Evolution. We continued on with our anole virtual lab, started learning about how pocket mice evolved to have darker fur to camouflage with volcanic rock in New Mexico,… Continue reading Week 2
There are two categories in which fruit can be divided by: fleshy and dry. Fleshy fruits can be divided, again, into fruits formed from a single flower and those formed from multiple flowers. Fruits can have only one seed or several seeds. Fleshy fruits formed from only one individual flower.
Fleshy fruits are classified as: Berry, Drupe, Aggregation of Drupes, Pome, Hesperidium. An example of a fleshy fruit is an avocado, as pictured above. Avocados only contain one large seed inside the fruit.
