There are five kingdoms of life. Bacteria belong in the kingdom called (a)
Bacteria can be found in
The land only
aquatic areas only
temperate places on land
every place ever
Which part of the bacteria is always present?
Cell wall
Plasmid
Flagella
Capsule
The (a) is used by some bacteria to move around in their environment
For LC, we learn about three types of bacteria: round, (a) and spiral
Bacteria reproduce in which way?
Sexually (binary fission)
Budding
Meoisis
Asexually (binary fission)
When do bacteria form endospores?
In the best environment, i.e. enough food, enough
When the temperature is ambient
In harsh conditions
When they are dormant
Some bacteria are autotrophs. This means they
eat each other
make their own food
become parasites
use chemicals to break down their food source
A (a) bacteria gets food from other organisms. They can be saphrophytes or parasitic bacteria.
If bacteria are in a temperature that is too high for them, their enzymes become (a)
A obligate anaerobe is a type of bacteria that
must have oxygen in its system
cannot have oxygen in its system
may or may not need oxygen
uses sulfur dioxide
The two economic disadvantages of bacteria are food spoilage and
parisitism
production of antibiotics
antibiotic resistance
human disease
The gene for antibiotic resistance is found in the (a) inside the bacterial cell. Not all bacterial cells have this structure.
Bacteria...
include yeast
are prokaryotic
do not grow in UV light
are eukaryotic
There are 5 stages in the growth of bacteria: (a) , log, stationary, decline and survival
There are two types of food processing we have to learn: (a) and continuous flow culture
We can produce products such as antibiotics or dairy products in a container known as a
petri dish
bioreactor
test tube
water bath
In batch culture, the product is collected during the two stages:
log and decline
log and lag
lag and decline
lag and stationary
In continuous flow culture,
there is more product
there are only two stages: lag and stationary
it is more used by the industries
you cannot do water treatments
How was the Quizziz :^)
