What kingdoms contain the oldest forms of life on earth?
Domain Bacteria contain the oldest known fossils of cells in bacterial cells.
Which group of microorganisms have the property of highly resistant endospores under certain growth conditions?
Group C. I'm in microbiology right now. Group A are vegetative forms of most bacteria and enveloped viruses that are easily killed by disinfectants. Group B are more difficult to kill, like tuberculosis baccillus and unenveloped viruses. and Group C have highly resistant endospores.
Why are microbial forms are the most resistant to disinfectants?

What resistant forms of bacteria are produced by gram resistant bacilli of the most dangerous disease causing bacteria?
endospore
A group of specialized cells first forms an what?
a group of specialized cells first forms into tissue, and a group of tissue forms into organs.
What kingdoms contain the oldest forms of life on earth?
Domain Bacteria contain the oldest known fossils of cells in bacterial cells.
How do these capsule and spores defenses affect the infection control measures that you need to take in a clinic?
Bacterial spores are extremely resistant and can survive most forms of disinfection and inadequate sterilisations
Which microbial forms are most resistant to disinfectants?
Microorganisms that are in a dormant or contain endospores are the most resistant.

How an isolated colony forms?
Certain Isolation techniqiues are based on the concept that if an individual bacterial cell is separated from other cells and provided adequate space on a nutrient surface, it will grow into discrete mound of cells called a colony

What problem might arise in histone-deficient chromatin?
Histones function in the packaging of DNA as well as in regulation of gene expression in eukaryotic (and some bacterial) cells. Histone proteins are among the most highly conserved proteins in eukaryotes, emphasizing their requirement for the survival of more complex life forms. Cells deficient in histones likely would not survive as the complex genomes of eukaryotes would not have the necessary levels of regulation as well as the DNA would not be efficiently packed and would be fragile and highly susceptible to damage.

What are the forms of bacteria growth and reproduction?
Binary Fission and Conjugation are two common forms of bacterial reproduction.
How do bacterial meningitis bacteria reproduce?
Bacterial Meningitis is a spore-forming bacilli. Bacteria typically reproduce by an asexual process called binary fission. Also called transverse division. A process by which one cell increases in size and forms two cells which are identical to each other.
What is antibiotic resistant bacteria?
Also known as "superbugs", antibiotic resistant bacteria have evolved to a point that our usual antibiotics won't kill them. VRE and MRSA are common forms of antibiotic resistant bacteria.
