The ability of organisms to maintain an internal environment independent of the external environment.
What is homeostasis?

treatment of bacterial infection
What is the primary and only use of antibiotics

Organism enters through skin wound (as small as a bug bite) Leads to extensive damage to muscle and fat
What is Necrotizing fasciitis

natural selection
What is an essential part of evolution?
200
RNA acts as an expendable copy of the DNA code
using RNa as a template for a protein synthesis instead of translating proteins directly from DNA serves as an advantage for the cell because...

gap junction
What is an intracellular junction that would allow for signal ,molecules to be passed between adjacent animal cells.
200
bactericidal directly kills bacteria upon exposure. Bacteriostaic inhibits the growth of bacteria
What is the difference between bactericidal and bacteriostatic?
200
Incubation: 2 – 10 weeks following resolution of primary syphilis Symptoms: Flu-like symptoms Leads to rash all over body including palms and soles – contagious!
What is Secondary syphilis
200
genetic variations exist within a population. populations tend to produce more offspring than the environment can support the best adapted individuals tend to leave the most offspring
What is natural selection based on?
300
tissues-organs-organ systems
list the order of biological organization from smallest to largest.
300
horizontal gene transfer-sharing genes with neighboring bacteria vertical gene transfer
What are some ways of sharing resistance among bacteria?
300
Transmission is via respiratory droplets Incubation: 2 – 4 days Symptoms: sore throat, pustules, fever (102)
What is Streptococcus pyogenes
300
Law of independent assortment
What is the law that states that the inheritance of one trait did not affect the inheritance of other traits?
400
Therpeutic cloning is used to produce stem cells for an individual with a medical condition, whereas reproductive cloning is sued to produce organisms identical to donor
what is the difference between therapeutic and reproductive cloning?
400
enzyme-mediated dehydration synthesis
After photosynthesis, plant cells begin the process of regulating the polymerization of glucose for more efficient and long term storage. This process would be described as?
400
Bacteria rapidly change phenotypes – high rate of recurring infections Viruses don’t change as fast, thus immunity after infection is common
Do you get sick from the same microbe twice?
400
Lockjaw: jaw muscles are often first affected Risus sardonicus: sustained contraction of facial muscles Trismus: contractions that do not break Symptoms can continue for years in survivors
What is Tetanus
400
A chance occurs in the environment poorly adapted individuals have decreased survivorship, leave fewer descendants well adapted individuals leave more offspring genetic frequencies with the population's gene pool change
given a population that contains genetic variation, what is the correct sequence of events that would occur under the influence of natural selection.
500
RNA polymerase bidn ans transcribes the template. mRNA is capped and edited mRNA binds to small ribosomal unit TRanslation complex is fully formed Next TRNA in sequence enters ribosome A peptide bond forms between the new amino acid and a polypeptide chain
what is the proper sequence of protein synthesis?
500
Glucose has all the elements for the synthesis of all other organic molecules, but other elements are required to produce proteins and nucleic acids.
Glucose from photosynthesis acts not only as a chemical energy source, but also as a precursor molecule used in the formation of proteins,lipids, and nucleic acids. WHAT IS TRUE REGARDING THE SYNTHESIS OF THESE OTHER MOLECULES.

Antibiotic Susceptible microbe is killed/inhibited by the antibiotic Antibiotic Resistant microbe is able to survive/grow in the presence of the antibiotic
