Module 13: Kingdoms of Life
This type of cell lacks a nucleus and is found in both archaea and eubacteria
What is a prokaryotic cell?
This process explains how populations change when individuals with favorable traits survive and reproduce more
What is natural selection?
These preserved remains provide direct evidence of organisms that lived in the past
What are fossils?
This describes a random change in DNA that introduces new alleles into a population
What is a mutation?
This term refers to all the alleles present in a population
What is a gene pool?
This kingdom includes organisms that absorb nutrients and act as decomposers
What is fungi?
This condition of natural selection describes producing more offspring than can survive
What is overproduction?
These structures share similar anatomy due to common ancestry, even if their functions differ
What are homologous structures?
This mechanism involves the movement of alleles between populations
What is gene flow?
This statement is true or false: Individual organisms evolve during their lifetime in response to environmental changes
What is false?
The organisms in this kingdom are considered highly diverse because they include plant-like, animal-like, and fungus-like forms
What are protists?
This term describes differences in inherited traits within a population
What is genetic variation?
These structures have similar function but evolved independently and do not share ancestry
What are analogous structures?
This process causes random changes in allele frequency, especially in small populations
What is genetic drift?
This statement is true or false: Mutations occur because organisms need to adapt to their environment
What is false?
This key difference separates animals from plants in how they obtain energy
What is ingesting food instead of photosynthesis?
This concept refers to an organism’s ability to survive and reproduce in its environment
What is fitness?
This field compares early development stages of organisms to determine evolutionary relationships
What is comparative embryology?
This type of genetic drift occurs when a population is drastically reduced in size
What is the bottleneck effect?
This type of structure has no current function but was inherited from ancestors
What is a vestigial structure?
These organisms are classified as extremophiles and are often found in harsh environments such as hydrothermal vents
What are archaea?
This incorrect idea suggested that organisms develop traits because they need them and pass them on
What is inheritance of acquired characteristics?
This concept states that all organisms share a common ancestor in the past
What is common descent?
After a course of antibiotics, most bacteria die, but a few survive and reproduce, causing a shift in allele frequency over generations.
What is antibiotic resistance?
This statement is true or false: Natural selection can increase the frequency of a beneficial trait in a population over generations
What is true?
