What are ecosystem services?
the benefits experienced by organisms, which are provided by the sustainable ecosystems.
Name an example of an ecosystem service
Wetlands storing water to reduce flooding risks
alpha university is

Beta diversity is

GAmma university is
Gamma universities is the overall diversity for the different ecosystems
Species diversity is

Genetic diversity is
Similar traits in species
Ecosystem diversity is

What is morphological identification
Focuses on body shake, size, plus structure, and relies on measurements and details.
Advantage - simple
disadvantage - Challenge deciding the variation.
what is biological identification
Focuses on ability to interbreed and produced viable fertile offspring
Advantage - concept is widely used
disadvantage - cant be used on separated populations
what is phylogenetic identification
Focuses on evolutionary relationship
- species is a cluster of distinct organisms.
adv = can be applied to extinct species
disadv - not all species are known for evolution
What does similarities in anatomical structures prove?
similarities in anatomical structures can be evidence of closer evolutionary relationships.
what are homologous structures
structures that come from common ancestors, so they have similar structure but different functions.
What are physiological relationships
genetic similarity or differences that are determined by composing proteins among species
DNA relationships are
genetic similarity or differences determined by composing DNA sequences.
Is bacteria prokaryotic or Eukaryotic?
Bacteria is Prokaryotic.
What’s the difference between gram positive and negative bacteria ?
Gram-positive bacteria has the crystal violet stain, where as gram-negative has a lipopolysaccharide layer that prevents the crystal violet stain from going past the peptidoglycan layer.
Peptido Glycan meaning?
Amino Acids, Carbohydrates.
Name the 5 steps of Binary Fission.
- Chromosome gets attached to point on cell membrane
- Chromosomes then replicate
- Cell membrane lengthens and moves chromosomes apart
- Membrane pinches inward
- Daughter cells become seperate
what are the 3 shapes and names of bacteria
Cocci (circle), bacillus (rod shape), and spirillum (Spiral)
Spirillum single name
spirilla
