Inheritance
What is inheritances?
When a parent passes on a specific trait to their offspring
What is natural selection?
Natural selection is having a specific trait in which which the chance of survival is increased among predators “survival of the fittest”
What is biodiversity?
The variety of life on the Earth.
How are ecosystem services beneficial?
Ecosystem services contribute to the wellbeing of humans and the quality of life for organisms
Describe the difference between dominant and recessive genes?
A dominant gene is a gene that is shown even when mixed with a recessive, a recessive gene is only shown when they genotype is two recessive alleles.
What is artificial selection?
Artificial selection is a process by which organisms are selectively bred according to their desirable phenotypic traits “selective breeding”
Why are so many species becoming extinct?
The relentless changes to the environment from: deforestation, poaching, and pollution.
Are non living components of an ecosystem important?
Yes, they are very important to ecosystems, especially oxygen and sunlight
Give three examples of inherited conditions.
Sickle-cell anemia, color blindness, hemophilia.
What is the study of paleontology and how does it support evolution?
The study of fossils and fossil records; by studying fossil, we can understand how the structure of organisms have changed over time
How is biodiversity measured?
By counting the number of species occurring in a given unit of area.
What are the four types of consumers in an ecosystem?
Herbivores, carnivores, omnivores, and decomposers
What is a mutation and how do they occur?
Mutations are changes in chromosomes and occur naturally or by radiation.
What is genetic equilibrium and what factors may cause this?
when the frequency of a gene pool does not change from generation to generation; genetic drift, mutation, etc.
Why is biodiversity so important, and what can we do to preserve it?
Biodiversity is a crucial factor for the performances of ecosystems. By protecting sensitive habitats
What ecosystem service would be helpful in terms of reducing greenhouse gases in the atmosphere?
High levels of primary producers and photosynthesis
What is a monohybrid cross?
A cross between two different organisms that differ by a single characteristic.
List five lines of evidence for evolution. What would happen if one line of evidence was missing?
Fossil records, comparative embryology, comparative biochemistry, geographic distribution, comparative anatomy.
What are endemic species?
Species in a limited area such as an island or a certain lake.
What features must an ecosystem have to be balanced?
Biotic and abiotic components; producers and consumers
