How are human cells specialised to stop bacteria entering it?
they are specalised by having a wall of agar jelly around the cells to prevent bacteria.
Why are nerve cells described as being specialised?
The only one of the 220 different types of Human Cells that is not specialized is the Stem Cell.
How are stem cells trnsplanted?
Stem cells are cells that have not specialised. Specialist cells can only be the one thing that they are specialised for; ie, you cannot turn skin cells into a heart, or liver cells into a brain. Stem cells have not specialised and can therefore become any type of cell. I am not sure how they are stimulated to become one kind or another, but they can. Adult stem cells are not as good as embryonic stem cells, but because harvesting embryonic stem cells requires the destruction of a human embryo it is banned in many countries.
What is the most common specialised cell?
Red blood cells are the most common specialized cells in the human body. They are responsible for carrying oxygen to tissues and removing carbon dioxide from the body.
How many cells are in the human body at birth?
As HUMANS, stem cells as they develop into our own specialised cells, as all animals start off as a fertilised egg, and it is our genetics that transform our stem cells into the many different specialised cells we need as humans.
What is the similarities of a human nerve cell and plant guard cell?
Both human nerve cells and plant guard cells are specialized cells that have specific functions within their respective organisms. They both have membrane-bound structures that control the movement of substances in and out of the cell. Additionally, both cell types respond to external stimuli to carry out their functions.
What part of a developing embryo are stem cells derived from?
Stem cells come from newly fertilized eggs.
What areas does salmonella affect in the human body?
digestive tract
How does pathogenic salmonella bacterium enter the human body by overcoming the bodys natural defenses?
Pathogenic salmonella can enter the human body through contaminated food or water. Once ingested, the bacteria can survive the acidic environment of the stomach and reach the intestine where they invade the intestinal cells, leading to infection. Salmonella can overcome the body's natural defenses by producing toxins and triggering inflammation, allowing the bacteria to multiply and spread within the body.
What is the size of a salmonella bacteria compared with a human cell?
50 nm
Why humans beings are complex organism?
humans beings have various types of cells which are specialized to do specitif function.
How long does the bacteria Salmonella typhi survive in a dead animals?
Salmonella Typhi is strictly a human pathogen. There are no animal reservoirs. Salmonella Typhimurium, on the other hand, is ubiquitous. I'd guess a few weeks, depending on conditions?
