Reading Passage:
A virus is made up of a strand of DNA or RNA covered by a protein coating. Viruses can infect animals, plants, and even bacteria. Like living things, viruses can evolve over time and adapt to their environment. Unlike living things though, viruses cannot use their genetic information (DNA) to reproduce by themselves; they need a living cell (called a host cell) in order to reproduce and respond to stimuli. Since viruses are not made up of cells, there is no need to maintain homeostasis nor do they require energy for metabolism (no need for food). Viruses only need energy when they make copies of themselves inside the host cell with the help of the energy produced by the host cell. Viruses do not grow or get bigger in size inside their protein coat.
Task:
Argument statement (claim): Viruses are alive.
Use your knowledge and examples from your notes to create a response that supports or refutes (disagrees with) the claim. Please cite at a minimum of 3 pieces of evidence to support your answer.
Match the following characteristics of life with their best description and/or example.
| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
Composed of cells | arrow_right_alt | Cells --> Tissue --> Organ --> Organ System --> Organism |
Evolution | arrow_right_alt | Organisms can either be unicellular or multicellular. |
Reproduce | arrow_right_alt | When a population of organisms change over time. (changing this answer from the snowshoe hare example) |
Organization | arrow_right_alt | Bacteria cells undergo a process known as Binary Fission when creating daughter offspring. |
Match the following characteristics of life with their best description and/or example.
| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
Respond to a stimulus | arrow_right_alt | When being outside on a hot summer's day, the human body tends to sweat to release heat and prevent heatstroke. |
Obtain and use energy | arrow_right_alt | Plants that are active during the day, tend to bend towards their light source. |
Grow and Develop | arrow_right_alt | Plants are autotrophic organisms that take in light energy to create high-energy sugars. |
Maintain homeostasis | arrow_right_alt | The common housefly starts out in a larva stage. |
Homeostasis is meant to imbalance the levels of things inside cells and organisms.
Select 5 common properties of living organisms.
