100

This term refers to microscopic organisms that include bacteria, fungi, and viruses.

What is a microbe?

100

These microscopic organisms can be found in nearly every environment on Earth, including soil, water, and the human body, and include both single-celled and multicellular forms.

What are microbes?

100

This is the basic process by which most microbes, including bacteria, reproduce by splitting into two identical daughter cells.

What is binary fission?

100

These microbes live on or inside the human body, helping with processes like digestion and immunity.

What are microbiota?

100

This bacterial infection is commonly known for causing sore throat and fever and is caused by Streptococcus pyogenes.

What is strep throat?

200

This process, carried out by certain microbes, involves the breakdown of organic matter to produce energy in the absence of oxygen.

What is fermentation?

200

These single-celled organisms lack a nucleus and can be classified into two major groups based on their cell wall structure: Gram-positive and Gram-negative.

What are bacteria?

200

This metabolic process allows certain microbes, like yeast, to produce energy without oxygen by converting glucose into either alcohol or lactic acid.

What is fermentation?

200

This term describes microbes that thrive in very hot environments, such as hot springs or deep-sea hydrothermal vents.

What are thermophiles?

200

This viral infection, which is spread by mosquitoes, causes fever, joint pain, and a rash, and is prevalent in tropical and subtropical regions.

What is dengue fever?

300

This term describes the study of microbes and their interactions with living organisms.

What is microbiology?

300

These microbes are unicellular eukaryotes and can be free-living or parasitic, with some species capable of causing diseases such as malaria and amoebic dysentery.

What are protozoa?

300

This process, carried out by some bacteria and cyanobacteria, converts light energy into chemical energy, producing oxygen as a byproduct.

What is photosynthesis?

300

Microbes that live in environments with high salt concentrations, such as salt lakes or salt mines, are known as this.

What are halophiles?

300

This bacterial infection, caused by Mycobacterium tuberculosis, primarily affects the lungs and can lead to persistent cough, chest pain, and weight loss.

What is tuberculosis?

400

The tiny structures found inside a bacterial cell that carry genetic information are called this.

What is a plasmid?

400

These organisms, often found in extreme environments, have unique biochemical properties and cell wall structures that differentiate them from bacteria, and they can include species that live in hot springs or highly saline environments.

What are archaea?

400

Some microbes can survive in the absence of oxygen by using alternative electron acceptors in a process known as this.

What is anaerobic respiration?

400

Microbes that live in extremely acidic environments, such as sulfuric hot springs or acidic mine runoff, are called this.

What are acidophiles?

400

This parasitic disease, caused by Plasmodium species and transmitted by mosquitoes, leads to fever, chills, and flu-like symptoms and is most common in tropical regions.

What is malaria?

500

The process by which bacteria can take up and incorporate foreign DNA from their environment is known as this.

What is transformation?

500

These non-living entities consist of a protein coat and genetic material (either DNA or RNA), and they require a host cell to replicate, causing diseases like HIV and influenza.

What are viruses?

500

This complex process involves the secretion of extracellular enzymes by microbes to break down complex organic compounds outside their cell, which are then absorbed for nutrition.

What is extracellular digestion?

500

These microorganisms can survive in environments with little or no oxygen and are often found in places like deep soil, swamps, or the intestines of animals.

What are anaerobes?

500

This potentially life-threatening disease is caused by Vibrio cholerae and is characterized by severe watery diarrhea, leading to dehydration and possibly death if not treated.

What is cholera?
