Study Notes

Regents Biology Review: Key Biology Knowledge for the Living Environment Exam

The Regents Living Environment Exam is a four-part exam that tests biology content knowledge and laboratory skills.
Levels of organization in life include populations, trophic levels, food chains, and ecosystems, with autotrophs and heterotrophs playing important roles.
Competition and natural checks in ecosystems help maintain stability, while carrying capacity limits population growth.
Homeostasis is essential for survival, and organisms have specialized cells and systems to maintain it.
Cells are the basic unit of life, with eukaryotic cells being more complex than prokaryotic cells.
Genes, inherited from parents, determine traits, but expression can be modified by the environment.
DNA is transcribed into mRNA, which is translated into proteins, and the sequence of amino acids determines protein structure and function.
Gel electrophoresis is used for forensic analysis, paternity testing, and studying evolutionary relationships.
Transgenic organisms are created for agriculture and industry using genes from multiple organisms.
Evidence from gel electrophoresis, embryonic development, fossil records, and morphology help construct the tree of life and gather evidence for evolution.
Mutations, caused by mutagens, can lead to variations in populations and passed onto offspring if they occur in sex cells.
The Regents website provides resources and sample questions for the Living Environment Exam.Evolution and Adaptation: Key Concepts in Biology
Evolution is the change in the frequency of different alleles over time.
Natural selection favors organisms that are better adapted to their environment.
Antibiotic resistance can arise in populations through natural selection.
Genetic diversity within a species increases its chances of survival in changing environments.
Behavioral, structural, and reproductive adaptations have helped organisms survive for millions of years.
A phylogenetic tree or cladogram is a tool for comparing evolutionary histories and relatedness among species.
Different branching patterns on a tree indicate how closely related different species are.
Individuals do not evolve, populations evolve through changes in allele frequencies.
Extinction can occur when a species lacks adaptive characteristics for survival.
The fossil record shows the history of life on Earth and the many extinct species.
These concepts are covered in the New York State Living Environment or Biology curriculum.
The next part of the video series will cover additional topics for exam review.
