after the first hour of death how many degrees does the body cool per hour

1 degree

which of the following terms indicate a bacteria that can only in an environment without oxygen? 1. aerotolerant 2. obligate anaerobe 3. microaerophile 4. Obligate aerobe

4. obligate anaerobe

Obligate Aerobes

Are microorganisms that can only live in the presence of oxygen.

Autotrophic Bacteria

Bacteria are self-nourishing bacteria capable of growing in the absence of organic compounds

obligate anaerobe

Botulinum

one of the largest groups of autotropic bacteria is

Cyanobacteria

Obligate aerobe

Ecoli

bacteria that can prefer an environment without oxygen but can live in an environment without it?

Facultative Anaerobe

By an large autotrophic Bacteria are highly pathogenic to human beings and contain some of the deadliest deceases known to man

False

once you kill a microorganism there is no way after its death that the microorganism can port you as the human body breaks it down

False

Microaerophile

Gonorrhea

Bacteria requiring an complex organic food from a carbon source

Heterotropic

Pseudomonas

Is a genus of bacteria that is commonly associated with secondary infections in burn patients.

what are the three broad categories of bacteria based on their temperature requirements requirements for growth

Psychrophiles, Mesophiles , Thermophiles

aerotolerant

Pyogeneses

Different Microorganisms have different food requirements

True

Regarding of size, every life-form has certain requirements that must be met to maintain life.

True

Temperature is a factor in the growth of microorganisms

True

A microorganism that is generally indifferent to an environment with oxygen

aerotolerant

when two or more species of organisms live together in close association and one is inhibited is is growth by the other

antagonism

Thermphiles

are Bacteria that prefers cold thriving at temp between Zero C and 25C(32-77F)

Listeria and Clostridium

are common culprits in cases of food poisoning

Obligate anaerobes

are microbes that can only survive in an environment devoid of oxygen.

thermophiles

bacteria that grows best in high temperatures between 40C and 70C (104-158F)

Mesophiles

bacteria that prefer moderate temperatures and grow best between 25C and 40C (77-104 F)

Facultative bacteria

can adapt to differing sources of nutrition

C. perfringens

is an anaerobic bacterium directly involved in the decomposition of human remains.

Strict Saprophytes are?

organisms that only survive on Dead or decaying organic matter.

Heterotrophic Bacteria

require complex organic foods from a carbon source to grow and develop.

Microaerophillic Microorganism

require little free oxygen ( about 2% to 10%)

a microorganism that only can survive in an environment devoid of oxygen

strict anaerobe

he general PH for a human body is 7.4

true

some bacteria grows in extremely high temperatures found inside volcanoes at 105Cand 110C (212-230F)

true
