What is the difference between logistic and exponential growth

Exponential=unlimited growth and rapid increase/ Logistic=starts exponential but slowly level off at carrying capacity

What is carrying capacity

Maximum population size of a species that an environment can support

Abiotic limiting factor

Non living factor that limits growth in ecosystem (sun water soil)

What are biotic factors

Living factors that involve predators competitors (parasites, diseases")

What is density dependent factors

Competition and predation and disease is an example, intensify as population grows

What is density independent

Natural disasters climate human activity, which happen regardless of the population

What is the difference from habitat and a niche

Habitat is the home they live in but a niche is the job in the habitat

What is the difference between intersocific and intrasoecific

Interspecific is of a different species

Intraspecific is of the same species

Explain competitive exclusion principle

Two species that compete for exact same limited resource like a home and can not coexist

Four different symbiotic relationship

Communism=both good

Parasitism=one bad one good

Mutualism=one good one chill

What are the four biogeochemical cycles

Water carbon nitrogen and phosphorous cycles

Three principles of cell theory

1. All living things are made of cells

2. The cell is the basic unit of life

3. All cells come from pre existing cells through division

Write six scientists

Compare and contrast prokaryote and eukaryotes

E=animals plants fungi protists thy have membrane and are larger unicellular or multi cellular

P=bacteria lack nucleus and organelles only unicellular

Both have DNA ribosomes cytoplasm and cell membrane

Three types of passive transport

Simple diffusion, facilitated, and osmosis, all move substances down concentration gradient with out energy

Hypertonic

Higher solute outside of cell so the cell shrinks

Hypotonic

The cell has too much solute so it explodes

Isotonic

Equal concentration

Homeostasis

Trying to make things equal and stable, if your sick then ur body raises its temp to make it harder for germs to survive

If cell has 46 chromosomes how many would each new cell have after cytokinesis in mitosis

46

Steps of mitosis

Prophase, metaphase, anaphase, and telophase

What is an enzyme

Biological catalyst, speeds up specific chemical reactions in living organisms

What is activation energy and how does an enzyme change it

Activation energy, the minimum energy for reactions to transform into products

What are factors that affect rate of a biochemical reaction

Temperature, pH, enzyme concentration, substrate concentration

What is the difference between competitive and noncompetitive inhibitors

Competitive binds to enzymes active site trying to move another one out

no competitive binds to a different site.

What is the difference between producers and consumers

Producers make their own food like plants while consumers get energy by eating other organisms like animals
