A microscopic organism that replicates exclusively inside the host’s cell, using parts of the host cell including DNA, ribosomes, and proteins
What is Virus
100
Requiring complex carbon and nitrogen for metabolic synthesis
What is Heterotrophic
100
A protein that accelerates a reaction by reducing the amount of energy required to initiate a reaction; also called a biological catalyst
What is Enzyme
100
A microorganism that can live with or without oxygen
What is Facultative anaerobe
100
A term that describes organisms that live in the absence of oxygen
What is Anaerobic
200
Virology is the study of ____________.
What is viruses
200
A ______________ is an entity by which infections are transferred, but the entity of transference does not have the disease and does not need to be a living organism. For example, a mosquito bite transfers malaria. In this case, the mosquito is the vector.
What is vector
200
Some forms of life cannot be seen without the aid of a _________________.
What is microscope
200
Robert Hooke is considered the Father of _________________; he devised the first compound microscope.
What is Microscopy
200
The average _________________ of an adult in the 1600s was 40 years; in contrast, midlife today is 40 years and many persons live into their 80s and 90s.
What is life span
300
Scientists have classified ______________ into seven different groups. These groups are based on structural similarities and the groups clarify how different organisms survive and interact with each other. This knowledge serves to aid scientists in understanding evolutionary changes.
What is organisms
300
Viruses are not included in the ______________________. Scientists differ on the classification of viruses because they do not fit nicely into the characteristics of a “life form.”
What is five kingdoms
300
_________________ cell walls contain a lipid that becomes toxic (endotoxins) when in the bloodstream of the host.
What is Gram negative
300
Four of the five kingdoms (Planta, Animalia, Fungi, and Protista) consist of _________________, whereas Monera is bacteria and prokaryotic.
What is eukaryotic organisms
300
Darwin formed taxonomic categories based on the phylogenetic (evolutionary) relationships between offspring from previous generations, contributing to our understanding of biology. He is considered the ________________________.
What is Father of Evolution
400
Louis Pasteur was able to show through his experiments that ____________ were responsible for spoilage of certain beverages, and thus paved the way for our understanding of germs.
What is bacteria
400
Many advances in scientific knowledge took place after _________________ experiments, from newly discovered bacteria to understanding the theory of evolution. It is no wonder that this period (approximately 1857-1914) was called the Golden Age of Microbiology.
What is Louis Pasteur’s
400
The most obvious difference between animal cells and bacterial and plant cells is the lack of a ___________________.
What is cell wall
400
___________________ lack the chloroplasts that plant cells use to store energy from the sun. Animal cells must manufacture their energy from food rather than from the sun. Inside each animal cell are many structures that work in unison. The nucleus contains the DNA of the cell. This is the genetic code of the animal. Other structures in the cell include ribosomes, mitochondria, Golgi complex, plasma membrane, cytoplasm, vesicles, and rough and smooth endoplasmic reticulum.
What is Animal cells
400
Malaria is caused by many species of protozoa. Plasmodium falciparum is the __________________ type of malaria that humans can contract. Female mosquitoes transfer this disease when they bite the skin. It is contained in their saliva. Symptoms include chills, fever, anemia, enlarged spleen, arthralgia, weakness, and vomiting.
What is most severe
500
The most common way to identify viruses is by their reaction with _______________.
What is antibodies
500
Viruses do not seem to replicate in any of the previously described methods; instead, they assemble themselves in the same way that cars are assembled in a processing plant. In all living organisms except viruses, DNA is double stranded. RNA is replicated from the DNA information. Viruses ______________ a host cell and take over this replication process to make more viral DNA.
What is invade
500
A term that describes organisms that need oxygen to survive
What is Aerobic
500
The study of life
What is Biology
500
Refers to microorganisms not visible without a microscope
What is Microbial
