Unit 1
This term refers to the ability of organisms to maintain a stable internal environment despite external changes
What is homeostasis?
This organelle is involved in synthesizing proteins and is found either floating freely in the cytoplasm or attached to the rough endoplasmic reticulum
What is the ribosome?
This type of symbiotic relationship benefits one organism while harming the other.
What is parasitism?
This type of transport does not require energy from the cell and moves substances down their concentration gradient.
What is passive transport or diffusion?
These organisms break down dead or decaying matter, recycling nutrients back into the ecosystem.
What are decomposers?
The strongest type of chemical bond.
What is ionic bond?
This double-layered structure controls what enters and exits the cell, maintaining homeostasis.
What is the cell membrane?
The maximum population size of a species that an environment can support indefinitely without being degraded is known as what?
What is carrying capacity?
This process involves the movement of water across a semipermeable membrane
What is osmosis?
In a food chain, this type of organism produces its own food through photosynthesis.
What is an autotroph or producer?
Water’s ability to dissolve a wide variety of substances makes it known as the blank.
What is a universal solvent?
This organelle is involved in detoxifying chemicals and metabolizing lipids, and it lacks ribosomes on its surface
What is the smooth ER?
The role of an organism in an ecosystem, including how it gets its food and interacts with other organisms, is called its what?
What is the niche?
This solution has the same concentration of solutes as the cell, causing no net movement of water.
What is isotonic solution?
This is the term for a group of individuals of the same species living in a specific area.
What is a population?
This allows water to have properties such as cohesion, adhesion, and high heat capacity.
What is polarity?
This organelle is responsible for modifying, sorting, and packaging proteins and lipids for delivery to other parts of the cell or outside the cell.
What is the Golgi?
This term describes a series of predictable changes in the species composition of an ecosystem over time, often following a disturbance
What is ecological succession?
This process requires energy in the form of ATP and moves molecules against their concentration gradient.
What is active transport?
This type of ecological succession occurs in an area that has not been previously inhabited, such as on bare rock after a volcanic eruption.
What is primary succession?
Tissue, cell, organ system, organ, body
What is cell, tissue, organ, organ system, body
This structure is responsible for breaking down waste materials and cellular debris and is sometimes called the "garbage disposal" of the cell.
What is the lysosome?
This ecological concept describes the maximum number of different species that can coexist in a community without competing for the same resources.
What is carrying capacity?
This process involves the cell engulfing large particles or fluids by extending its membrane around them to form a vesicle
What is endocytosis?
The phenomenon where nitrogen-fixing bacteria convert nitrogen gas from the atmosphere into a form usable by plants is called blank
What is nitrogen fixation?
