Example: Euchromatin is important for the transcription of genes in the cell.

Definition: Connected to the study or practice of improving the genetic quality of a population, often through selective breeding.

Example: The eugenic policies of the early 20th century aimed to enhance the genetic traits of future generations.

Definition: In a way that relates to the study of improving the genetic quality of a population, often through selective breeding.

Example: The scientists discussed the implications of their research eugenically, considering the ethical aspects of genetic selection.

Definition: A person who supports or studies the idea of improving the human population through controlled breeding and genetics.

Example: The eugenicist argued for policies that would promote genetic health in future generations.

Example: Euglena can be found in ponds and lakes, where they play a role in the ecosystem.

Definition: A type of single-celled organism that belongs to the family Euglenidae, often found in freshwater environments and known for its ability to photosynthesize and move using a whip-like tail called a flagellum.

Example: Euglenids are fascinating organisms that can both photosynthesize and consume food from their environment.

Definition: A type of single-celled organism that belongs to a group of flagellates, often green or colorless, and usually has one or two whip-like structures for movement.

Example: Euglenoids are often found in freshwater environments and can photosynthesize like plants.

Definition: A type of simple protein that can dissolve in weak salt solutions but not in pure water.
