Ecology
This term refers to the variety of life in a particular habitat or ecosystem.
What is biodiversity?
This process, where a substance naturally moves from high to low concentration, is critical to the delivery of necessary molecules to and the removal of waste products from functioning cells,
What is diffusion?
This term refers to the semi-permeable envelope that surrounds the cell, controlling the movement of substances in and out.
What is the cell membrane? [or plasma membrane?]
This term refers to a testable statement predicting the outcome of an experiment, often formulated as "If… then…"
What is a hypothesis?
What is mitosis?
These organisms obtain their energy by consuming other organisms, as opposed to producing it themselves.
What are consumers?
This feedback mechanism, which tends to resist changes, returns an organism back to its normal state.
What is negative feedback?
These molecules are critical for the cell to undergo cellular respiration, which produces ATP.
What are glucose and oxygen?
In an experiment, this group serves as a standard for comparison and does not receive the experimental treatment.
What is a control group?
In sexual reproduction, this type of cell contains half the number of chromosomes and is involved in the formation of a zygote. Examples include sperm and ova (eggs).
What is a gamete?
This type of relationship between two species involves one species benefiting while the other is harmed.
What is parasitism?
This term describes the state when an organism's internal conditions, such as temperature, pH, and hydration levels, remain in balance despite constant changes.
What is dynamic equilibrium?
This structure contains the genetic material (DNA) and controls the cell's activities, often referred to as the "control center" of the cell.
What is the nucleus?
This variable is deliberately manipulated by the experimenter to observe its effect on another variable.
What is the independent variable?
This organ of the female reproductive system is responsible for nurturing and protecting a human embryo.
What is the uterus?
This process involves the gradual replacement of one community by another, often following a disturbance.
What is ecological succession?
This hormone, released by the pancreas, plays a crucial role in regulating blood glucose levels, critical for maintaining homeostasis.
What is insulin?
These structures are the sites of protein synthesis in the cytoplasm. It attaches to mRNA and helps attract amino acids and bind them together.
What are ribosomes?
This molecule was too large to move through the semi-permeable membrane in the "Diffusion" cell model lab setup, demonstrating why the human body must digest it into glucose.
What is starch?
This term refers to the union of male and female gametes to form a zygote.
What is fertilization?
This term describes the maximum population size that an environment can sustain indefinitely, given the available resources.
What is carrying capacity?
This process, where a substance is pumped from low to high concentration with the help of ATP energy, is useful in maintaining certain cellular environments. One example comes from the contractile vacuole of unicellular algae found in freshwater ponds, which expels excess water entering the cell through osmosis.
What is active transport?
This organelle produces ATP for use in many other areas of cell metabolism by undergoing cellular respiration.
What is the mitochondrion?
What is gel electrophoresis?
This term refers to the process whereby a cell becomes specialized through gene expression, often changing shape and function to match its neighbors.
What is differentiation?
