Vocabulary
The process of organisms changing to better suit the conditions of their environments.
Adaptation
These are the organisms that all organisms receive their genes from.
Parents
This term explains a skill organisms use to hide from predators by blending in with their environments.
Camouflage
Name the two populations of juncos we have talked about in class.
USCD & Mountain juncos.
What kills bacteria?
Antibiotics
The process in which organisms that are better adapted to their environments tend to survive & produce more offspring.
Natural Selection
Humans inherit how many alleles for each gene, and where do they come from?
Two alleles — one from each parent.
Most organisms, such as human & juncos, reproduce by this method.
Sexually
They are more used to being around people.
In a frog population, some frogs jump farther than others. When a new predator arrives, long-jumping frogs escape more easily.
→ Which process best explains the future increase in long-jumping frogs?
Natural Selection
This term describes the process by which all species adapt over time to their environments.
Evolution
The term that refers to the passing of traits from one generation to the next.
Inheritance
Each human parent passes on this number of chromosomes to its offspring.
23 (half)
Which junco population is more adept to surviving in the wild?
Mountain juncos.
Why do individuals with favorable traits become more common over many generations?
They produce more offspring with those traits.
A threadlike structure that carries genetic information in the form of genes.
Chromosome
If a mutation gives some bacteria resistance to antibiotics, what term do we use to describe this bacteria?
Antibiotic resistant (ance)
This is the process in which bacteria use to reproduce.
Binary fission
Why might the color of the two population of juncos vary slightly?
Human body cells are called this term.
Somatic cells.
The amount of and visual appearance of chromosomes in the cells of organisms, functioning primarily to display all of the chromosomes in a body cell.
Karyotype
An alteration to an organisms DNA that can lead to adaptations.
Mutation
Modern giraffes have long necks because this trait made long-necked giraffes the most ________ to survive their environment.
Fit.
Which of the two populations of juncos we've talked about likely have the larger wing span?
Mountain Juncos
This term explains the growth rate of organisms such as bacteria, increasing with rapid acceleration over time.
Exponential growth.
