How are bacterial cells different from plant and animal cells?
Bacterial cells different from plant and animal cells is because plant has a cell wall and animal cells don't.
Why is heat shock important in bacterial transformation?
Heat shock is important in bacterial transformation because it helps the bacterial cells take up foreign DNA more efficiently. The sudden increase in temperature makes the cell membranes more permeable, allowing the DNA to enter the cells more easily. This increases the chances of successful transformation, where the foreign DNA is incorporated into the bacterial genome.
Why did detergent disrupt the bacterial cell membrane but not destry our skin cell?
I guess that is because bacterial membrane has different phospholipids, phospatidyl ethanolamine while we have phosphatidyl choline. I don't think all detergent can disrupt the bacterial membrane, but antibacterial soap.
Why use isopropyl alcohol to inhibit bacterial growth?
Isopropyl alcohol is commonly used as a disinfectant because it can kill a broad range of bacteria by denaturing their proteins and dissolving their lipid membrane. It evaporates quickly, which helps in reducing bacterial contamination on surfaces. This makes it an effective choice for inhibiting bacterial growth in various applications.
How can dilution streaking be effectively utilized in microbiology experiments to isolate and identify specific bacterial colonies?
Dilution streaking is a technique used in microbiology to separate and identify individual bacterial colonies. By diluting the sample and streaking it on an agar plate in a specific pattern, the bacteria are spread out, allowing for the growth of individual colonies. This makes it easier to isolate and identify specific bacterial species present in the sample.
What is bacterial photosynthesis?
How bacteria makes their food. (Like a plant, only different materials) LucilleBall 1Fan
Who makes bacterial infection difficult to defeat?
bacteria produced quickly
Are there types of tableware that are anti-bacterial?
Yes, Harfield Tableware makes anti-bacterial tableware. Usually this kind of tableware is used for hospitals, schools, or nurseries.
How is a plant cell different from a bacterial cell?
Plant cells have additional structures like chloroplasts, a large central vacuole, and a cell wall made of cellulose, which are not present in bacterial cells. Bacterial cells lack membrane-bound organelles like a nucleus and typically have a simpler structure compared to plant cells. Additionally, plant cells are eukaryotic, while bacterial cells are prokaryotic.
What effect does heat-fixing have on bacterial cell size?
it makes cell size shrink
What makes strep throat be a bacterial infection?
Strep throat is caused by beta haemolytic streptococci. They are bacteria.
Does iron in water affect copper pipes?
Yes, it rots them and also makes unsightly bacterial sludge.
How are bacterial cells different from plant and animal cells?
Bacterial cells different from plant and animal cells is because plant has a cell wall and animal cells don't.
How do bacteria eliminate waste?
They eat our waste and secrete their own. Much bacterial waste makes plant nutrients.
What is the process called when a bacterial cell makes copies of its DNA then divides making two identical cells?
Mitosis
Do bacteria eliminate waste?
They eat our waste and secrete their own. Much bacterial waste makes plant nutrients.
Why does penicillin not affect human cells?
This is essentially because bacterial cells and human cells are very different. Both bacterial and human cells use chemicals called enzymes to build their walls. Penicillin is the right chemical "shape" to chemically stick to part of the bacterial enzyme. When it does this, it stops the bacterial enzyme from working properly and this makes the bacterial cell walls weak. The weakened cell wall cannot withstand the outside pressure, it breaks up and the bacterial cell dies. Human cells are made by different types of enzymes with a different chemical shape that penecillin is unable to stick to so it cant stop the human enzymes from working. The human cell walls are thus unaffected by it and they remain strong.
