There were a variety of different types of control methods used into today’s lab (i.e. hot sauce, mouth wash, alcohol, etc.). Which one(s) do you think will work effectively and why? Think about what part of the cell would be affected by the control and explain.

5. How can cells become different types of cells, such as nerve cells? A. by going through the stages of mitosis B. through the division of the parent cell Copyright © 2020 Illuminate Education, In

3. You are interested in testing the effect of a drug on human cells. These cells have been sampled and evenly split into two separate cell cultures. You trigger cell division using a growth factor in both cell cultures. This synchronises the start of mitosis so you can easily detect the effect of the drug on the progress through the mitotic phases. Immediately after mitosis begins, you expose one cell culture to the drug (treatment + drug) and compare their progress through the mitotic phases under the microscope to the cells that are not exposed to the drug (control - drug). Here are your observations: ● ● Cells from both cell cultures lack their nuclear membranes. Individual chromosomes are clearly visible in both cell cultures Cells from the control culture (- drug) have their chromosomes aligned (see figure below) Cells from the treatment (+ drug) have their chromosomes dispersed in the cell (see figure below). What effect does the drug have on the chromosomes? Indicate two…

2. Two examples of chemotherapeutic drugs (drugs used to treat cancer) and their cellular actions are listed below. Explain why each drug could be fatal to a cell. a. Vincristine: damages the mitotic spindle

The activity provides you with a version of the NGF pathway, an example of a RTK. All of the proteins involved can be in ON/OFF states. Using this cell signaling pathway you will be asked a variety of questions to determine how the molecules are regulated, but also how a cell would respond if this cell signaling party steps were interrupted or activated.

6. Consider the process of transduction. Describe the process in terms of the cell that donates the genetic material and the cell that receives it. For full credit, include and define any key vocabulary words needed to understand the process.

1. As a science student, you're working in the lab using your compound microscope. The room is quite dim-lighted with only fluorescent lamp on. You're examining a plant cell with a light green color and it seems that it's hard for you to get a clearer view of its nucleus. What must be done to make your study successful? 2. Donating a pint of blood reduces blood volume, which results in a decrease in blood pressure (just as air pressure in tire decreases as is let out of the tire). What effect does donating blood have on heart rate? What would happen if a negative feedback mechanism did not return the value of some parameter such as blood pressure to its normal range? Please only answer these questions briefly. Thank you

1. Make a simple statement concerning what you can conclude from (Simulated facilitated Diffusion). What have you learn from this lab? 2. Make a simple statement concerning what you can conclude from the experiment.

Read the descriptions and write in the name of the cell organelle. Use the organelles listed in the word bank. Identify if the description is the organelle's structure or function, by circling. Color the organelle the color listed on the cell(s). Cell Membrane Nucleus Mitochondrion Vacuole Cell Wall Cytoplasm Chloroplast Lysosome
