Population
What is an example of a disease caused by a virus?
Influenza
Hepatitis B
Hepatitis C
Herpes
When did life originate on Earth?
3.5 BYA
Do prokaryotic cells have a nucleus?
No-DNA is contained in the nucleoid
What is a symbiosis?
Two organisms living in close association
An alternate form of a gene
Allele
This disease, caused by prions, is a fatal neurological disease affecting deer.
What is Chronic Wasting?
What are some ways we can construct a phylogenetic tree? (Name 3)
Embryonic analysis (developmental), morphology, physiology, genetic data, fossil records
What are the biological causes of the Black Death?
Infection by bacteria (prokaryote) Yersinia Pestis
Describe and endospore
A protective coating produced by a bacteria during times of environmental stress.
The process by which acquired energy, stored in bonds of molecules (e.g., carbohydrates), is converted to a usable form (ATP)
Cellular Respiration
How do prions reproduce?
Attacking a healthy protein and causing it to fold incorrectly and change-this causes malfunction of the protein and then death of the organism.
Name 3 ways phylogenetic trees benefit humans?
Agriculture- New Crops
Health-Antibiotics, pathogen detection, etc
Conservation Biology-Increase genetic diversity in populations
How do prokaryotes reproduce?
Fission
Name the 5 characteristics of living things
1.Consist of one or more cells.
2. Reproduce
3.Possess Genetic Information
4.Products of Evolution
5. Use energy
GREECE (WITH NOTHING IN LAST E)
Genetic information, reproduction, evolution, energy, cells, NOTHING
An evolutionary process by which individuals with an advantageous inherited trait (an adaptation) produce more surviving offspring than individuals without this trait.
Natural Selection
What disease causing agent caused an outbreak between 1918 and 1920 and led to the death of 50 million people?
Virus-Influenza
Name the order in which life on Earth evolved
Heterotrophic bacteria, Cyanobacteria, Protists (Eukaryotes), Plants, Fungi, Animals
What are the social causes of the Black Death?
Poverty and lack of understanding of disease
What two organelles that we discussed in lecture can be attributed to Eukaryotic cells through the Endosymbiosis Theory?
Mitochondria and Chloroplast
Change in the relative abundance (or frequency) of alleles (or heritable traits) in a populationover time.
Evolution
What are the characteristics of an organism that a virus has?
1) capacity to reproduce
2) hereditary information
3) capacity for evolution
Why was the evolution of cyanobacteria important for further evolution of life on Earth?
*Ozone Layer
*Oxygen in atmosphere
How does gene transfer occur in Prokaryotes?
Conjugation
Describe the difference between heterotrophy and autotrophy
Heterotrophy-an organism must consume other organisms/acquire nutrients outside of themselves to gain energy
Autotrophy-Can create their own energy
