What are three methods that are used to identify bacteria?
Three common methods used to identify bacteria include Gram staining, biochemical tests, and molecular techniques such as polymerase chain reaction (PCR) or sequencing of the bacterial genome. These methods help to determine the characteristics of the bacteria, such as cell wall composition, metabolic characteristics, and genetic makeup, which aid in identification.
How and why do pathogenic bacteria enter host cells?
Pathogenic bacteria enter host cells basically for "food and shelter", and to hide from the host's immune system. Under normal circumstances, the phagocytic cells of the immune system engulf the bacteria and/or tag them for destruction by other means. This keeps the bacteria away from other cells. Studies indicate however, that pathogenic bacteria enter non-phagocytic cells via receptor-mediated endocytosis. The bacterium has a surface protein that a protein on the host cell recognizes. The cell is then fooled into believeing that the bacterial protein is one that needs to be destroyed or recycled. Since the cell's protein destruction machinery is inside the cell, it brings the bacterium into the cell via endocytosis. And the rest is history!
What part of the cell controls what substances leave or enter the the cell?
The cell membrane controls what substances enter or leave the cell. It is a selectively permeable barrier that allows certain molecules to pass through while blocking others. This regulation helps maintain the internal environment of the cell.
What is part of a bacteria cell?
A bacteria cell is where all of you r bacteria gather up
How does a bacteria cell differ a plant or animal cell?
A bacteria cell differs structurally from plant and animal cells because of its small size. A bacteria cell has flagella outside of the cell to help it move. A bacteria cell does not contain organelles. Only the chromosome and sometimes ribosomes are visible in a bacteria cell.
Are bacteria in a cell?
No, bacteria are not normally found in cells. The cell walls keep them out. But some kinds of bacteria can actually enter some cell types. Use the link below to the related question to get the scoop on this. Bacteria is a cell itself
What digests nutrients wastes and bacteria that enter the cell?
your body
By what process are bacteria brought into a cell?
Bacteria can enter a cell through a process called phagocytosis, where the cell engulfs the bacteria using its cell membrane. Alternatively, some bacteria can invade cells by injecting proteins that manipulate the host cell machinery to gain entry.
Which of the methods cannot be used to enter data in a cell?
pressing the exc key.
Why do plant cells have a cell wall and an animal cell do not?
because animals need to have bacteria enter their mouths to survive
What can kill bacteria effectively?
There are several methods that can effectively kill bacteria, including heat, disinfectants, antibiotics, and UV light. These methods work by either destroying the bacteria's cell walls, disrupting their metabolic processes, or damaging their DNA.

What do lysosomes remove?
the remove harmful molecules from your body, they also digest bacteria that enter the cell.
Identify at least five ways by which a substance may enter the cell?
A substance can enter a cell through diffusion, facilitated diffusion, active transport, endocytosis, or passive transport. Each of these processes has different mechanisms for moving substances across the cell membrane.

How infective agent enter to body?
Germs and bacteria enter the body through several different methods. Sometimes when another person sneezes or when you shake hands with an infected person you will catch their germs. Bacteria can also come from the food we eat not being cooked thoroughly.
What do Penicillin's do?
Penicillin is an antibiotic. Penicillin is used to treat many different types of infections caused by bacteria, such as ear infections prescribed by doctors for bacterial infections in woundsDestroys the cell walls of the bacteria allowing the bacteria's cytoplasm to exit the cell as well as allowing water and ions to enter, causing apoptosis of the bacteria.
