Definition: The process by which an organism develops from an egg or spore, involving the differentiation of unstructured cell masses into specialized organs and systems.

Example: The concept of epigenesis explains how complex organisms develop from simple beginnings.

Definition: Relating to changes in gene activity that do not involve alterations to the DNA sequence itself, often affecting how genes are expressed in an organism.

Example: The study of epigenetic factors has revealed how environmental influences can affect gene expression.

Definition: In a way that relates to the changes in gene expression that do not involve alterations to the underlying DNA sequence.

Example: The researchers studied how environmental factors can influence gene expression epigenetically.

Definition: The branch of biology that studies how genes are turned on or off and how these changes can be passed down to future generations without altering the DNA sequence.

Example: Researchers are exploring the role of epigenetics in how environmental factors can influence gene expression.

Definition: Related to the flap of tissue at the back of the throat that covers the windpipe during swallowing.

Example: The epiglottal sounds in some languages are produced by using the epiglottis.

Definition: Related to the flap of tissue at the back of the throat that covers the windpipe during swallowing.

Example: The doctor explained how the epiglottic function helps prevent food from entering the airway.

Definition: A small flap of cartilage at the back of the throat that covers the windpipe when you swallow, preventing food and drink from entering the lungs.

Example: The epiglottis closes off the windpipe during swallowing to ensure that food goes down the esophagus instead.

Definition: The study and interpretation of ancient writings and inscriptions, often found on monuments or artifacts.

Example: The archaeologist specialized in epigraphy, analyzing ancient texts to understand historical events.

Definition: The external reproductive organ of female arachnids, which is involved in mating and reproduction.

Example: The epigyne is a crucial part of the female spider's anatomy, allowing for the reception of sperm during mating.

Definition: This term describes a type of flower structure where the floral parts are connected to the top of the ovary, making it seem like they are growing from there.

Example: The apple tree has epigynous flowers that bloom in the spring.
