A common name for cyanobacteria is ___ bacteria.
- A.
Black-green
- B.
Red-green
- C.
Blue-green
- D.
Green
Correct Answer
C. Blue-greenExplanation
Cyanobacteria are commonly known as blue-green bacteria because they have a bluish-green pigmentation due to the presence of chlorophyll-a and phycocyanin pigments. These pigments allow them to carry out photosynthesis, converting sunlight into energy. The term "blue-green" accurately describes the coloration of these bacteria, distinguishing them from other types of bacteria.Rate this question:

Bacteria never have
- A.
Cell walls
- B.
Membrane- bound organelles
- C.
Chlorophyl
- D.
Genetic material
Correct Answer
B. Membrane- bound organellesExplanation
Bacteria do not have membrane-bound organelles because they are prokaryotic organisms. Prokaryotes, including bacteria, lack a true nucleus and other membrane-bound organelles such as mitochondria or endoplasmic reticulum. Instead, their genetic material is located in the cytoplasm in a region called the nucleoid. This is in contrast to eukaryotic organisms, which have membrane-bound organelles that perform specific functions within the cell.Rate this question:

Cocci are bacteria that have a ____ shape
- A.
Spiral
- B.
Sphere
- C.
Rod
Correct Answer
B. SpHereExplanation
Cocci are bacteria that have a sphere shape. This means that they are round or spherical in appearance. Unlike other bacteria such as spiral or rod-shaped bacteria, cocci have a distinct circular shape. This shape allows them to easily divide and reproduce, as well as adhere to surfaces. Cocci can be found in various environments and can cause a range of infections in humans and animals.Rate this question:

What is the role of bacteria in the ecosystem?
- A.
They are the source of energy for photosynthesis
- B.
They produce sugar and oxygen
- C.
They act as primary consumers
- D.
They decompose nutrients from dead organisms
Correct Answer
D. They decompose nutrients from dead organismsExplanation
Bacteria play a crucial role in the ecosystem by decomposing nutrients from dead organisms. This process, known as decomposition, helps break down organic matter and releases essential nutrients back into the environment. By decomposing dead organisms, bacteria contribute to the nutrient cycle, allowing these nutrients to be recycled and used by other living organisms. This helps maintain the balance and sustainability of the ecosystem.Rate this question:

Spirilla are bacteria that have a ___ shape
- A.
Spiral
- B.
Rod
- C.
Sphere
Correct Answer
A. SpiralExplanation
Spirilla are bacteria that have a spiral shape. This means that they are curved or coiled in a spiral pattern, resembling a corkscrew or a spring. The spiral shape allows them to move efficiently through various environments, such as water or mucus. This shape also provides them with increased surface area, which aids in nutrient absorption and attachment to surfaces. Overall, the spiral shape is a defining characteristic of spirilla bacteria.Rate this question:

A process of the food energy that is used to kill harmful bacteria is ___.
- A.
Vaccination
- B.
Botulism
- C.
Nitrogen-fixing
- D.
Pasteurization
Correct Answer
D. PasteurizationExplanation
Pasteurization is the process of heating food or beverages to a specific temperature to kill harmful bacteria, viruses, and other microorganisms. This process helps to extend the shelf life of the product and ensure its safety for consumption. Unlike vaccination, which is a method of preventing diseases by introducing a weakened or killed pathogen into the body, pasteurization directly targets and eliminates bacteria in the food. Botulism refers to a type of food poisoning caused by a toxin produced by the bacterium Clostridium botulinum. Nitrogen-fixing is a process in which certain bacteria convert atmospheric nitrogen into a form that plants can use for growth.Rate this question:

Place a checkmark on all the foods that are made using helpful bacteria.
- A.
Yogurt
- B.
Cheese
- C.
Vinegar
- D.
Meat
- E.
Sauerkraut
- F.
Milk
Correct Answer(s)
A. Yogurt
B. Cheese
E. SauerkrautExplanation
Yogurt, cheese, and sauerkraut are all foods that are made using helpful bacteria. Yogurt is made by fermenting milk with specific strains of bacteria, which helps to break down lactose and create a creamy texture. Cheese is also made using bacteria, which helps to ferment and age the cheese, giving it its distinct flavor and texture. Sauerkraut is made by fermenting cabbage with lactic acid bacteria, which not only preserves the cabbage but also creates a tangy flavor. Vinegar is not made using bacteria, and meat is not typically made using helpful bacteria.Rate this question:

Some bacteria produce thick walls around themselves called
- A.
Saprophytes
- B.
Antibiotics
- C.
Endospores
- D.
Nitrogen-fixing
Correct Answer
C. EndosporesExplanation
Endospores are a type of protective structure produced by certain bacteria. These structures are formed when the bacteria enter a dormant state, allowing them to survive in harsh conditions such as extreme temperatures, lack of nutrients, or exposure to chemicals or radiation. The thick walls of endospores provide resistance against these adverse conditions and protect the genetic material of the bacteria. Once the environment becomes favorable again, the endospores can germinate and the bacteria can resume their normal metabolic activities.Rate this question:

Most bacteria reproduce by
- A.
Mating
- B.
Spore formation
- C.
Budding
- D.
Fission
Correct Answer
D. FissionExplanation
Bacteria reproduce through a process called fission, where a single bacterium divides into two identical daughter cells. This is the most common method of bacterial reproduction and allows for rapid population growth. Mating is not a common method of bacterial reproduction, as bacteria do not have sexual reproduction. Spore formation is a method used by some bacteria, but it is not the primary method. Budding is a method of reproduction seen in certain types of organisms, but it is not the primary method for bacteria. Therefore, fission is the correct answer.Rate this question:

Farmers save millions every year on fertilizer costs with ____ bacteria.
- A.
Archaebacteria
- B.
Nitrogen-fixing bacteria
- C.
Saprophytes
- D.
Eukaryotic
Correct Answer
B. Nitrogen-fixing bacteriaExplanation
Farmers save millions every year on fertilizer costs with nitrogen-fixing bacteria. Nitrogen-fixing bacteria are able to convert atmospheric nitrogen into a usable form for plants, reducing the need for synthetic fertilizers. This symbiotic relationship between the bacteria and plants helps to enrich the soil with nitrogen, promoting healthy plant growth and reducing the financial burden on farmers.Rate this question:

Bacilli are bacteria that have a ___shape.
- A.
Rod
- B.
Sphere
- C.
Spiral
Correct Answer
A. RodExplanation
Bacilli are bacteria that have a rod-shaped structure. This means that they are elongated and cylindrical in shape, resembling a small rod or stick. Unlike spherical bacteria, which are round, or spiral bacteria, which have a spiral shape, bacilli have a straight and elongated appearance.Rate this question:

Some types of bacteria live in nodules (growths) on the roots of certain plants, turning the nitrogen from the air into nitrogen that can be absorbed from the soil. Both the bacteria and the plants benefit from this kind of relationship, called
- A.
Consumerism
- B.
Mutualism
- C.
Parisitism
- D.
Competition
Correct Answer
B. MutualismExplanation
Mutualism is the correct answer because it describes a type of relationship in which both parties involved benefit. In this case, the bacteria and the plants have a mutualistic relationship because the bacteria provide the plants with nitrogen that they can absorb from the soil, while the plants provide the bacteria with a habitat and nutrients. Both the bacteria and the plants benefit from this interaction, making mutualism the appropriate term to describe their relationship.Rate this question:

Check all that apply to methane producers.
- A.
they can be found in swamps
- B.
they live in the intestines of cattle
- C.
they are aerobic
- D.
They are used in sewage treatment
- E.
They can be used as a fuel
- F.
They are in the Kingdom Eubacteria
- G.
They live only near deep ocean vents
Correct Answer(s)
A. they can be found in swamps
B. they live in the intestines of cattle
D. They are used in sewage treatment
E. They can be used as a fuelExplanation
Methane producers can be found in swamps because the anaerobic conditions in swamps provide an ideal environment for the production of methane. They also live in the intestines of cattle, where they help in the digestion process and produce methane as a byproduct. Methane producers are used in sewage treatment to break down organic matter and produce methane as a renewable energy source. Additionally, methane can be used as a fuel for various purposes.Rate this question:
