Ecology
What is a population?
Group of all living organisms of the same species living in the same environment at the same time
This is the most common type of prokaryote (hint think of a common example/type of organism we have talked a lot about)
What is bacteria?
What do antibiotics do to bacteria?
Antibiotics kill bacteria
Are viruses considered living organisms? Why?
What is no, for many reasons including but not limited to lack of reproduction, regulation, metabolism, etc.
A type of feedback lap that counteracts change, to maintain homeostasis
What is a negative feedback loop?
This kind of growth can be modeled by its characteristic "J-curve"
What is exponential growth?
What kind of living things are smaller/simpler, unicellular, and especially defined by having no nucleus or membrane-bound organelles
What are prokaryotes?
What is the term for when bacteria becomes strong enough to fight off the effects of antibiotics?
What is antibiotic resistance?
This characteristic about life is about breaking glucose into energy and is heavily related to breathing
What is respiration?
A type of feedback loop that involves continuously greater increases until a terminating event shuts down the loop
What is a positive feedback loop?
This kind of growth curve can be modeled by its characteristic "s-curve"
What is logistic growth?
Get both right for points:
1. Do prokaryotes need a host to reproduce?
2. Do prokaryotes ever live without genetic material?
1. No (only viruses do)
2. No, required
What is the name of the nutrient filled gel at the bottom of petri dish plate growing bacteria?
What is agar
These words altogether, can be abbreviated as STERNGRR
What is Synthesis, Transport, Excretion, Regulation, Nutrition, Growth and Development, Respiration, Reproduction?
Regulation of temperature (i.e. sweating when hot or shivering when cold) is this kind of feedback loop
What is a negative feedback loop?
Factors that are crucial to further growth in number of a population - sets the carrying capacity as there are not enough of these resources to maintain too many organisms
What are limiting factors?
What is the name for which bacteria multiply from 1 into 2 genetically identical clones
What is binary fission?
This term describes the area around an antibiotic in a plate where bacteria do not grow
What is the zone of inhibition?
What is the last R in STERNGRR which not all living things require (only needed to keep populations alive over time) and what are the two types?
What is reproduction and what is sexual and asexual
This kind of feedback loop with blood sugar is disrupted when a person with diabetes type I cannot create insulin
What is negative feedback loop?
This kind of graph/growth models an environment where there are unlimited resources
What is exponential growth?
These four cell structures are shared by both prokaryotes and eukaryotes
What are DNA/RNA, cell membrane, cytoplasm, and ribosomes?
What does a larger radius for the zone of inhibition reveal?
That the antibiotic is more effective than another kind of antimicrobial
What are the two types of regulation?
What is homeostasis and stimulus and response?
This kind of feedback loop is involved in birthing and blood clotting where oxytocin continues being released and platelets are exponentially activated in each process respectively
What is a positive feedback loop?
