i need the answer quickly

Direction: Read and analyze the following laboratory experiment and answer the following question. PART 1: SURFACE AREA AND CELL SIZE Materials: Agar containing NaOH, and the pH-indicator dye phenolphthalein cured into cubes of various size, 3 plastic cups, HCl, metric ruler, paper towels. Methodology: 1. Safety: Wear goggles and nitrile gloves while completing this lab. 2. Obtain three different size blocks of pink or blue agar. Using a ruler, measure the length, width, and height of the three blocks given below. Cut the agar according to the given dimension. Small = 1 cm x 1 cm x 1 cm Medium = 2 cm x 2 cm x 2 cm • • Large = 1 cm x 1 cm x 6 cm 3. Record your data. 4. Pour HCl or vinegar into two small cups. Place the one larger "cell" into one cup and the two smaller cells in the other cup. Start timing 30 minutes. 5. After 30 minutes, remove the cells and blot them dry with a paper towel. 6. Using your ruler, measure the distance the HCl has diffused into the blocks as shown on the…

question: Can you summarize and explain for me what you want to tell in the article below? Can you explain the figure?  When I read it myself, I do not understand exactly what is meant by the article. It would be nice if you could highlight the important points. You can use them in a figure or diagram to explain. thank you and hava a nice day :) Article:  Nanotechnology Tools to Detect SARS-CoV-2 Standard procedures for detecting the virus from nasopharyngeal and/or oropharyngeal swabs have been reviewed recently and are primarily based on reverse transcription polymerase chain reaction (RT-PCR). Here, we would like to mention some preliminary ideas on nanotechnology-based assays to monitor the presence of SARS-CoV-2. A simplified test and variants thereof to detect viral proteins (e.g., HIV or influenza virus) without the need for expensive equipment is based on the color change of Au NPs bound to antibodies. Similar to the enzyme-linked immunosorbent assay (ELISA) antibodies coupled…

The expression of ACE2 probably determines uptake by different tissues. In addition to discussing immune-based approaches, because the lung is the most critically affected organ, we will center our discussion on the various options to inactivate the virus in the deep lung and to target the essential host cells for drug delivery. The virus reaches the alveoli and enters alveolar epithelial type II cells (AECII), due…

You can use them in a figure or diagram to explain. thank you and hava a nice day :) Article:  Nanotechnology Tools to Inactivate SARS-CoV-2 in Different Environments Outside the Patient SARS-CoV is highly stable at room temperature and at 4 °C, but it is inactivated by ultraviolet light at 254 nm, highly alkaline or acidic conditions of pH >12 or pH <3, respectively, or by brief (e.g., 5 min) heat treatment at 65 °C. SARS-CoV-2 is expected to be similarly sensitive. Several human coronaviruses can be inactivated by classical disinfectants, including bleach, ethanol, povidone-iodine, chloroxylenol, chlorheximide, and benzalkonium chloride, so we expect similar inactivation with SARS-CoV-2. The virus stability on surfaces…
