Evolution
The core theme of biology, which explains both the unity and diversity of life, is
evolution
The pelvis bones in a whale represent this type of evidence
comparative anatomy
The process which individuals with favorable inherited traits are more likely to survive and reproduce
Natural selection
Increased size through cell division and cell enlargement is this stage of development
Differences between cell types result from
gene expression
Aristotle believed that
species are fixed (permanent)
Imprints or remains of organisms that lived in the past represents this line of evidence
paleontology
In artificial section, humans choose the desirable traits. In natural selection this chooses the desirable traits
Environment
Chosen for the ease with which they can be studied in the laboratory
model organisms
A protein that binds to an enhancer and stimulates transcription of a gene
Activator
This scientist believed new structures appear in an individual and can be acquired in response to a need
Lamarck
All living organisms are made of cells represents this line of evidence
molecular biology
Inherited characteristic of organisms that enhance their survival and reproduction in specific environments
Adaptation
The movement of cells from the blastula surface to the interior of the embryo
Gastrulation
Skin cells differ from nerve cells mainly because they
Express different genes
The ultimate source of all new alleles is.....
a mutation
Vertebrate forelimbs come a common ancestor and are said to be this
homologous structures
A biological term that describes how successful an organism has been at passing on its genes to the next generation
Fitness
Material inside the maternal egg that are important for early development
cytoplasmic determinants
______ are essential for the transcription of all protein-coding genes
General transcription factors
A change in allele frequencies in a population over generations is known as
Microevolution
Broccoli, cabbages, and Brussels sprouts all descend from the same wild mustard and can still interbreed. These varieties were produced by....
artificial selection
According to Darwin, this has given rise to the diversity in life
decedents with modifications
Process that sets the development fate of a cell- commits cell to becoming certain kind of tissue/cell
Determination
Gene expression is the process by which DNA directs the synthesis of _____
Proteins
