Step by step
Solved in 2 steps
- In monolayer cell culture conditions contact inhibition occurs when the following conditions are meet suspension cells form masses confluent monolayers of cells are present and cell division continues confluent monolayers of are present and cell division stops Nuclear overlap of cell monolayers occursThe series of photos above shows you plant cells when looked at with a light microscope. The first image is taken with a 4x objective lens. We always look through an ocular lens (eyepiece of a microscope) which in this case has a 10x magnification. This means tha the total magnification for the first image is 40x (meaning 40 times as big as you could see with the naked eye). The second image is using the 10x lens, with a total magnification of 100x. The third image is taken using a 40x objective, with a total magnification of 400x! What does each box in the microscope image represent? A. each box is an organelle B. each box is an animal cell C. each box is a plant cell D. each box is a nucleusWhich of the following is an advantage of confocal microscopy over conventional fluorescence microscopy? The interaction of the laser beam with the cell surface allows the imaging of individual macromolecules O Only out-of-focus light enters the microscope lens, making the object appear illuminated against a dark background The use of electrons instead of light to image the specimen results in greatly increased resolving power O Optical sections in a single plane of focus can be visualized at different depths in the specimen The natural contrast of an unstained specimen is enhanced
- Plant Cell (Ideal Model) This is a model of an ideal plant cell. Objects are not to scale and many of them would not be visible with a compound light microscope. Fill in the blanks. CIIDExamine the micrograph of the yeast cells. The scale bar under thephoto is labeled 1 µm. The scale bar works in the same way as ascale on a map, where, for example, 1 inch equals 1 mile. In thiscase the bar represents one thousandth of a millimeter. Using thescale bar as a basic unit, determine the diameter of the matureparent cell and the new cell. Start by measuring the scale bar andthe diameter of each cell. The units you use are irrelevant, butworking in millimeters is convenient. Divide each diameter by thelength of the scale bar and then multiply by the scale bar’s lengthvalue to give you the diameter in micrometers.Please write the advantages and disadvantages of animal cell culture.
- label cell structures. the photo is of stained mammalian cellsthat are under under a compound light microscope at 400x total magnification. the cells were treated with cell fixing agent, methylene blue stain, and eosin stain.Look at the picture below to measure the size of the cells. 1. The following parameters were selected: 。 Group A 。 Cell #1 2. The 1000-micrometer ruler was selected to measure the smallest cell. 3. Based on your observation what is the size of the cell? 1000x pivot interactives 630x ruler 1000x ruler * 100 micrometers 0 μm 20 μm 40 μm 60 μm 80 μm 100 μ 50 micrometers 70 micrometers Can not be determinedCan you explain why using bio printing is better than SLA and which materials would be best to use for Bio priting out of collagen, fibrin or silk.
