Pathogens
What are antibiotics used for?
Treating bacterial infections
Explain the different types of Limiting Factors.
Biotic= all living limiting factors
Abiotic= all nonliving limiting factors
What does survival of the fittest mean?
The most suited organism for the environment will live long enough to pass on the favorable traits to their offspring.
Explain how fossils can help provide evidence for evolution.
Shows changes over millions of years.
What drives the water cycle?
The sun
What are the main types of pathogens?
Fungi, bacteria, virus and parasites
Draw an example of a graph showing what the relationship between predators and prey would look like through several years.
when prey is high, predators are high
when prey goes down, predators soon follow
Why is genetic diversity significant?
Gives better chances to produce favorable traits to the population.
What and analogous structures and explain how they can help provide evidence for evolution.
Same function but not structure.
Trick Question: They do not show a common ancestor.
What provides the energy that fuels most ecosystems?
The Sun
What is the difference between the treatment and prevention of a disease?
Treatment= after
Prevention= before
Explain the difference between a food chain and a food web.
Food chain= one path of energy
Food web= multiple paths of energy
Explain natural selection.
Survival of the fittest
What are homologous structures and explain how they can help provide evidence for evolution.
Same structure, different function. Organisms have change the structure based on what they need for example, arms to flippers.
What organisms have the most energy in an ecosystem?
Plants aka autotrophs aka producers
Explain outbreaks, epidemics and pandemics.
Outbreak= more than normal in a small area
Epidemics= multiple countries in the same region
Pandemics= world-wide spread
Explain how photosynthesis and cellular respiration relate to each other.
The products of one reaction are the reactants of the other reaction.
Explain what Darwin observed while on this expedition to the Gallopacos Islands.
Species were adapted to their own island.
What are vestigual structures and explain how they can help provide evidence for evolution.
Structures still present, but no longer useful. If you have it now, it served a purpose a long time ago.
Name AND explain the different types of symbiotic relationships.
Mutualism= both benefit = plants and pollunators
Parasitism= one benefits, one hurt = mosquito and people
Commensialism= one benefits, one doesn't care = whale and barnacle
Name and explain the best ways to prevent ALL the major pathogens.
Virus= vaccine
Bacteria= cook food fully and good hygiene
Parasites and fungi= good hygiene
Explain what an energy pyramid shows.
Energy decreases as it is passed along. Only 10% is transfered between the levels.
What can organisms that have unfavorable traits not do?
reproduce and pass on their traits
What is the study of organism development and explain how this can help provide evidence for evolution.
Embryology
Many different organisms do not start to look different until late stages of development.
What is the difference between an ecological relationship and a symbiotic relationship?
Ecological relationships are how organisms interact with each other, symbiotic relationships are how they work together.
