- The nucleotides are the biding blocks of nucleic acid, which made of: O Nitrogenous base O Both a and b Sugar and phosphate groupPlaced into a solution with 20% total solutes (_% water) *solution is to the cell *What happens to cell volume? Placed into a solution with 0% total solutes ( % water) cell with 20% total solutes *solution is to the cell % water) *What happens to cell volume? Placed into a solution with 50% total solutes ( % water) *solution is to the cell *What happens to cell volume?Please label this red onion cell image with a drop of water under the microscope. Include all relevant labels including: nucleus, cell wall, cell membrane, cytosol, vacuole, etc. Kindly explain why there's a large white stop at the top and bottom left. What conclusions do you draw from these results? Discuss this by referring to what type of solution this would be considered (eg. hypertonic, hypotonic or isotonic).
- Why is the cell membrane described as a "fluid mosaicA) The size of a cell seen under a microscope is 3mm Using a total magnification of 40x. What is the actual cell size and decide if the cell is prokaryote or eukaryote based on its size?All of the following are correctly matched and can be found in bacteria EXCEPT: Cell (plasma) membrane – encloses cytoplasm; phospholipid bilayer with proteins None of the other four answers (all are correctly matched and can be found in bacteria) Cell wall - contains peptidoglycan Nucleus – membrane-bound organelle containing multiple chromosomes Ribosomes – site of protein synthesis
- i have 4 homework questions related to cell transport. i answered them with the help of my notes but just wanted to verify if my answers are correct and if they are not then an explanation would be helpful. so can you confirm if the following bolded answers are correctly selected: 1. Two molecules that can pass easily through the plasma membrane, between phospholipids, include a) oxygen and starch b) salt and water c) starch and salt d) water and oxygen e) starch and water 2. When comparing two solutions, the one with more dissolved solutes is said to be a) hypotonic b) hypertonic c) isotonic d) in equilibrium 3. Turgor pressure builds up in a(n)_________ cell when it is placed in a(n)_______ solution. a) plant, hypotonic b) plant, hypertonic c) plant or animal, isotonic d) animal, hypotonic e) animal, hypertonic 4. The scent of a burning candle fills the entire room. This process is an example of a) osmosis b) diffusion c) endocytosis d) facilitated diffusion e) none of the aboveQUESTION 1 Why is heat or a VERY long incubation required to stain Mycobacteria? mycotoxins present in the bacteria break down the stain; heating destroys the mycotoxins allowing the stain to enter the cells. waxy mycolic acids present in the bacteria break down the stain; heat prevents the stain from breaking down. waxy mycolic acids present in the bacterial cell walls prevent the stain from entering at room temperature; when heated, some stain is able to penetrate the cells. mycotoxins in the bacteria prevent the stain from entering the cells; heating inactivates the mycotoxins QUESTION 2 Micrococcus luteus was used as a negative control in an acid fast staining procedure - what does it mean to be a negative control? THERE ARE 2 CORRECT ANSWERS O Negative control bacteria are NOT expected to stain with acid fuschin. Negative control bacteria are expected to stain. Negative control bacteria are expected to stain only when heated. A heat-fixed smear of negative control bacteria is an…You have two types of cells (animal cells and plant cells) that you will place in a variety of conditions. Please describe what would happen to each of those two cells in the following solutions, i) isotonic solution; ii) hypertonic solution; iii) hypotonic solution.

After reading differences between prokaryotic and eukaryotic, I am not sure if one of these other options could also be selected (and if so, why?) Thank you for your help.Which of the following microscopes typically requires the use of vital dyes (like methylene blue) to visualize large subcellular structures in a living cell (like the nucleolus or the mitochondrion)? the scanning/tunneling electron microscope (STEM), with good resolution up to about 100,000,000x the transmission electron microscope (TEM), with good resolution up to about 100,000x the scanning electron microscope (SEM), with good resolution up to about 1,000,000x the compound light microscope, with good resolution up to about 1,500x all of the above microscopes would be equally useful in visualizing the interior of organelles14 Question 18 Il Pause Q Zoom Q Review /v Finish Te ABG Section 1 - Question 18 Directions: The picture below shows cells being viewed through a scanning electron microscope.
