Unit 8.1 Bed Bugs
how traits can change in an environment over time.
| Question | Answer |
|---|---|
| how are genes and traits connected | in this process the gene determines the structure, this determines the function of the protein, which then determines the trait that we see. |
| mutations impact the trait of an organism | mutations result in an alteration to the trait, for example a four leaf clover plant instead of a three leaf clover. |
| mutations can have three impacts on an species survival | beneficial, neutral, or harmful |
| A beneficial trait such as camouflage can be distributed over time in a population | when the beneficial trait becomes more common in a population |
| How do you determine if a mutation is beneficial | a trait is beneficial if it becomes more common over time and increases the chances of survival and or reproduction. |
| Natural selection | traits that help an organism survive are more likely to occur in a population |
| How can the environment impact traits | changes to the environments conditions result in adaptations, natural selection allows organisms with desired traits to have a higher survival/reproduction rate , causing over time those traits to be more common in the population. |
| steps to determine the traits of an organism | gene - protein structure- protein function - trait |
| Heritable | When a trait is able to be passed from parent to offspring |
| Distribution | The way that related traits are divided in a population of organisms. |
| Natural Selection | The process by which individual organisms with traits that are beneficial in their environment are more likely to survive and produce more offspring. |
| Adaptation | A change over many generations in the distribution of inherited traits in a population that causes organisms in the population to be better able to reproduce. |
| Resistance | The ability to not be affected by something that is normally harmful. |
| A sequence of DNA that determines the structure of a protein. The combination of genes on the chromosomes determines what proteins are made in the cell. | Gene |
| Large complex molecules that are responsible for traits. They make up the structure and control most functions and chemical reactions in living cells. | Protein |
| A random and permanent change to a genetic material in a gene. These are rare in nature. | Mutation |
| The chances or likelihood that something will happen. | Probability |
| Environmental Conditions | Variables in the environment such as food and water availability, water quality, temperature, air quality, topography, habitat, and natural hazards. |
| A characteristic of an organism; many traits are inherited (genetic). | Trait |
| Population | A group of organisms of a species living in the same environment over time. |
