Biology chapter 39

While exploring a cave, a person breathes in fungal spores that causes a lung infection

Airborne

The human lymphatic system is important in

All of the above

Bacteria are responsible for the following diseases

All of these

Scientists think the first bacteria on earth were

Anaerobic

Involves the protection of antibodies

Antibody

Key role played by antigen-antibody complex

Antibody

Tissue fluid is found

Around body cells

Circular chromosome is copied

Binary fission

Two identical cells are produced

Binary fission

Clones of killer t cells produced

Cellular

T cells destroyed by pathogens directly

Cellular

Memory cells produced so the body can respond quickly to a second attack

Cellular and antibody

Simulated by antigens in the body

Cellular and antibody

What are the 3 different shapes of bacteria

Circular, rods, and spirals

Bacterium with a new genetic makeup is produced

Conjugation

Genetic material is transferred through a pilus

Conjugation

Sexual reproduction occurs

Conjugation

What are the 3 growth patterns

Diploid, strepto, staflo

After having unprotected sex, a person contracts syphilis

Direct contact

Bacteria return nutrients to the environment by breaking down

Inorganic materials

As an endospore, a bacterium

Is protected

Nitrogen is important because all organisms need it to make

Proteins

A reservoir for lymphocytes that can be transformed into specific disease fighting cells is the

Thymus gland

A child born to a woman who is infected with hiv is at risk for being infected too

True

It is important for researchers to try to discover new antibiotics because many types of bacteria are becoming resistant to ones now being used

True

The cause of death for a person with aids usually is some type of infection that the body's weakened immune system can no longer fight off.

True

The majority of untreated persons infected with hiv will develop aids

True

The toxin produced by a particular microorganism might be far more destructive than the direct damage the microbe does to it's host cells

True

The virus that causes aids is well named because it attacks the immune system

True

Bacteria that are obligate anaerobes release energy from food by

Using nitrogen

A person contracts Rocky Mountain spotted fever after being bitten by a tick

Vector

Due to reduced death rates from bacterial diseases and improved sanitation and living conditions, the average person born in the us today will live to be about

75 years old

Endemic diseases often dissappear in a population, only to resurface unexpectedly many years later

False

Hiv can be transmitted by air

False

Hiv destroys a person's resistance to disease by attacking and destroying memory t cells

False

If a person is infected with hiv, he or she will usually develop aids within about a year

False

If you catch the flu during an influenza epidemic, your best hope of recovery is to take antibiotics

False

In a blood sample from an hiv positive person, you would expect to find most of the viruses existing free in blood, rather than being hidden inside cells

False

The main function of lymph nodes is to

Filter lymph

What structure do some bacteria use to move

Flagella

Botulism is caused by endospores of c. Botulinum that have

Germinated

The process by which bacteria use enzymes to convert nitrogen gas into ammonia is called

Nitrogen fixation
