science Flashcards
What are the difference between Abiotic and biotic
Abiotic: are non living ex) rocks sun
Biotic: are living things ex) wolf humans
Explain what species is
Living things of the same kind that are able to reproduce
Explain population
All individuals of one species living in a certain place at the same time
What is community
All population of different species living and interacting in the same place
What are the basic needs of a living organism in order to survive
Water Energy Food Exchange gases Habitat Wast disposal
what is symbiosis
The relationship between species where at least one species benefits
What is parasitism
The relationship between where one species benefits and the other is harmed (+,-)
What is mutualism
Where both species benefits (+,+)
What is commercialism
Where one species benefits where the other isn’t harmed
What is behavioural adaptations
Things organisms do to survive
What are structural adaptations
Physical features like fur on a bear
What is the difference between a dump or landfill and sanitary landfill
Sanitary are designed not to leak. a clay liner and system of pipes is put in place to prevent leakage
What is the difference between consumer and producers
Producers: living things at beginning of food chain making its own food
Consumer: living things that relies on other living things for food
What are Carnivora
Feed on animals or animal parts
What are herbivores
Feed on plants
What are omnivores
Feed on both animals and plants
What are the three main processes responsible for the water cycle
Evaporation, condensation, precipitation
What is bioinvasion
Accidental or planned introduction of a non native species into a community
Describe the difference between primary succession and secondary succession
Primary succession: occurs when there is formation of a new community of what was ones barren habbitat
Secondary succession: occurs when there is a formation of a new community in a destroyed or greatly changed community
What is pioneer species
The first species to be established in a certain habitat
What is climax community
A general stable community that has a wide range of species; the temporary end of succession
What are the difference between threatened endangered extirpate and extinct
Threaten-describe a species who’s numbers are declining
Endangered-describes a species that is so rare that is in danger of disappearing or becoming extinct
Extinct-describes a species that is no longer on earth
Extirpated-describes a species that no longer exists is a specific area though it still exists elsewhere
What is meant by sustainable life style
A lifetime that can be maintained or continued; capable of being used indefinitely, often referring to the use of resources
Explain the plant structure roots is
Absorb water and dissolved nutrients; anchor the plant in the soil
Explain the plant structure stem
Provides pathway for movement of water and food; support the leaves and reproductive structures
Explain the plant structure leaves
Produce food for the plant; take in and release oxygen and carbon dioxide allow water to exit the plant
Explain the plant structure flowers
Each flower usually has both male and female parts for reproduction
Explain the plant structure seeds
Contain an embryo that will form a new plant; contain a food supply for the embryo
Explain the plant structure cones
There are separate male and female cons for reproduction
Explain life process transpiration
The evaporation of water from the surface of the plant mainly from the leaves transpiration pulls the water up from the roots
Explain the life process of diffusion
The movement of particles from a area of high concentrations to an area with low concentration
Explain the life process of osmosis
The movement of water particles from a cell with high water concentration to low
Explain the life process of photosynthesis
The process by witch plants use light energy, carbon dioxide, and water to make their own food
Explain the life process of cellular respiration
The process in witch cells break down sugar particles into carbon dioxide, water, and energy
What are the three stages of the life cycle of a typical seed plant
Seed —>seedling—>adult
Explain the process of pollination
Occurs after a pollen grain lands on a stigma of a flower it is the process witch male and female parts of a plant join to produce a seed
What organisms are considered to be pollinators
Species of bird insect and bats can be pollinators
What are the three types of vegetative reproduction
Runners, rhizomes and suckers
What are the difference between cutting and graphing
Cutting is small pieces of a plant that usually have a part of the stem a few leaves graphing is attaching a part of one plant to another
Give an example of food
Fruits and vegetables
Give an example of fibre
Wooden house frame and plywood cloth for clothing and paper products
Give an example of Medicine
Tea made from white spruce and hemlock was used to cure scurvy
aesthetics
the pleasing appearance or effect that an object has, (not all structures need to be aesthetically pleasing)
beam bridge
the most common bridge used, is flat, and supported at 2 ends. a longer beam bridge may be supported by other stuff
arch bridge
designed to with stand heavy loads. the dynamic loads of people cause pieces of wood or stone in arch to push against the pieces.
truss bridge
light weight, but strong, made of trusses (triangle) along its sides.
suspension bridge
hangs between two ends that holds it up, modern one has tall towers on ends that supports main cables. those cables are anchored in concrete, smaller cables support roadway
performance requirements
conditions that a structure must meet. performance requirements also apply to many other aspects of a structure like safety, effectiveness, and purpose
what do you have to verify in a structure
the climate, culture, tradition, tech, economics
what is deformation
change of shape in a structure or any structural component, because the material is unable to resist the load acting on it.
