BPA is a chemical compound that has historically been used in the manufacture of plastic products. However, cells often mistake BPA compounds for hormones that accelerate the cell cycle. Because of this, BPA is associated with an increased risk of certain cancers. Question: Why do you think that very small concentrations of BPA might have a large effect on the cell?

Mitosis: Naming the Stages of Mitosis The pictures of the mitotic stages below are NOT in the correct chronological sequence. Name each stage of mitosis, A to E. Each answer choice is used once and only once. E. Picture A [Choose ] Picture B (Choose ] Picture C [Choose ) Picture D Choose] Picture E Choose]

Artificially induced apoptosis (controlled cellular death) is found to be an effective treat- ment for some forms of cancer. Which of the following describes the most likely mechanism by which apoptosis might be induced? A B с D by causing ribosomes to increase the rate of protein synthesis by triggering the division of mitochondria in the cell to increase ATP production by increasing the expression of membrane-bound glucose protein channels by causing lysosomes to release digestive enzymes into the cytosol

How does the dysregulation of cell cycle checkpoints contribute to the development of cancer?

of my celle chose are wels smaller than normal. According to Model 1, what part(e) of the cell cycle is (ere) ou likely being affected? Some cancerus me 7. In Model 1, if the length of the arrow represents time, then for those cancerous cells, what hap pens to the time that is necessary for the cell cycle? What implication might this have for doctors who are treating cancer patients? Why? Living things must grow and develop. At times they suffer injuries or damage, or cells simply wear out. New cells must be formed for the organism to survive. What process must occur to make a new, properly- functioning cell? Model 1 - Mitosis as Part of the Cell Cycle Prophase Metaphase Anaphase Mitosis How do living things grow and repair themselves! Replicated chromosome (2 sister chromatids) 0000 * Centriole Spindle fibers Nuclear membrane Telophase 1. Refer to Model 1. List the four phases in the mitosis process. 2. Where is mitosis in the cell cycle? Before 3. What three phases of the cell cycle…

If a starfish sustains damage to an arm, it often grows a new one, as long as part of the central disc is still attached (known as regeneration). If a gecko loses its tail, it may regenerate a new one.  If a person damages their spinal cord, mobility is often impaired. Which type of cell is less likely to go through the cell cycle after being damaged— starfish arm, gecko tail or human spinal cord? Explain in terms of the cell cycle.

Cancer, the uncontrolled growth of cells, often results in a tumor, or mass of abnormal cells. Some cancerous tumors consist of many cells that are much smaller than normal. According to Figure 1, what part of the cell cycle is most likely being affected? Explain.
