Scientific Method
What are the independent variable?
Independent is the variable you're changing
600
What is biodiversity?
The diversity in an ecosystem between animals
What is the relationship between Carbon Dioxide and temperature?
By adding more carbon dioxide to the atmosphere, people are supercharging the natural greenhouse effect, causing global temperature to rise.
What are the cell types and explain differences and similarities
Eukaryotic, prokaryotic, plant and animal cells
Eukaryotic has a membrane
Prokaryotic does not
What is the dependent variable?
The variable you're measuring
The process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere
What are invasive species and how do they affect biodiversity?
Succession and it's phases?
The five stages of plant succession are primary succession, secondary succession, young forest, old forest, and climax community. When an environment reaches a climax community level, it is balanced or in equilibrium. Environmental disturbances to secondary succession can set back plant succession
Osmosis, hydrophobic and hydrophilic?
The spontaneous passage or diffusion of water or other solvents through a semipermeable membrane
Hydrophobic means you hate water, Hydrophilic means you adore it
What is the controlled variable?
Controlled Variables is the one that stays the same
What is carrying capacity?
The capacity in which a population can maintain.
What are the reactants and products of photosynthesis and cellular respiration?
Erosion?
The process of eroding or being eroded by wind, water, or other natural agents.
What is the process of an enzyme?
Enzymes speed up (catalyze) chemical reactions in cells
What are the components of the graph?
Title, X Axis, Y axis, Measurements, line
What are limiting factors?
Limiting factors are things that limit the population
What are the main purposes of cellular respiration and photosynthesis?
The main purpose of photosynthesis is to convert radiant energy from the sun into chemical energy that can be used for food. Cellular respiration is the process that to breaks down sugar in the presence of oxygen to release energy in the form of ATP.
Factors that affect erosion?
Climate, soil properties, vegetation, soil cover, and land management practices
What are the functions of each of the following organelles; nucleus, mitochondria, chloroplast, ribosome, and the plasma membrane.
Nucleus: controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information
Mitochondria: Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions.
Chloroplast: a type of plastid (a saclike organelle with a double membrane) that serves as the site of photosynthesis
Ribosome: an intercellular structure made of both RNA and protein, and it is the site of protein synthesis in the cell.
Plasma Membrane: the membrane found in all cells that separates the interior of the cell from the outside environment
How do you formulate an appropriate hypothesis for an experiment?
You take the research question and answer it
What are the trophic levels? Identify each individually once you've gotten them.
Autotroph, heterotroph, producer, primary consumer, secondary consumer
Be able to describe the biosphere, geosphere, hydrosphere, and atmosphere and how they interact.
Biosphere: The region in which life exists
Geosphere: Rocks, rocks, whole lotta rocks
Hydrosphere: The water
Atmosphere: The stuff in space that protects us
Increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species
Describe the structure of the plasma membrane
A lipid bilayer that is semipermeable---semipermeable means that only some things can enter and leave but others can not
