unit 1
Is the human body open system or closed system?
Open system
What are the inputs of photosynthesis
H20, C02, light
Describe the producer, herbivore, and carnivore
producer produces its own food, herbivore eats only plants, carnivore eats animals only.
What is the vestigial structure?
Remnants of once important structures that gradually have lost all or most of their functions over time.
Which sphere of earth's system means constructed or modified by humans?
anthrosphere
How many phosphate groups are in ATP?
3
What is the difference between the food chain and a food web
food web is a complex network and food chain is a chain
Difference between homologous structure and analogous structure
homologous- similar in structure
analogous-similar in function
what does biodiversity mean
a measure of the number of different species found within a specific area
List the organization of the biosphere in order
1. organism
2. Population
3. community
4. ecosystem
5. biome
6. biosphere
Where does photosynthesis take place in?
chloroplast
what is the 10% law.
when the percentage of the energy transfers to the trophic levels when energy gets lost as heat.
Which DNA is passed down genetically through mother's only.
mitochondrial DNA
what is cellular respiration
releases chemical energy from sugars and other carbon based molecules
What's the difference between habitat and niche
habitat is all biotic and abiotic components. niche includes physical chemicals
inputs and outputs for cellular respiration
input: O2 and glucose
outputs: C02, H20, ATP, Heat
Is evaporation a reservoir or process?
process.
what are hox genes?
helps to guide the process that results in the development of an organism's characteristics body plan.
what are the reactants and products for photosynthesis and cellular respiration
photosynthesis:
reactants- CO2, H2O
products- O2, C6H12O6
Cellular respiration:
reactants- O2, C6H12O6
products- H2O, CO2
Describe the difference between density-dependent and density independent factors.
Density dependent are factors that are affected by the number of individuals in an area.
Density independent are factors that can impact a population regardless of its density.
What causes your muscles to burn?
fermentation (lack of oxygen)
How much percent of the Earth's atmosphere is composed of nitrogen gas?
78%
Birds and snakes share a common ancestor from over 250 million years ago, but now they show many physical differences. These differences are most directly the result of...
the long term accumulation of mutations.
first stage: Krebs cycle- completes the breakdown of glucose started in glycolysis and fuel the production of ATP
second stage: The electron transport chain-uses proteins embedded in the inner membrane of the mitochondrion.
