From the options you provided, both "a" and "d" can be living things. However, it seems that "a" and "d" are repeated. If you can provide more information or specific options, I can help you determine which one(s) are living things in the given environment.
To determine which object in the given list is a living thing, we need to understand the characteristics of living organisms. Living things, also known as organisms, have certain key attributes:
1. Organization: Living things are composed of cells and organized into higher levels of biological structure such as tissues, organs, and organ systems.
2. Reproduction: Living things have the ability to reproduce and pass their genetic information to the next generation.
3. Growth and development: Living organisms undergo growth, resulting in an increase in size or number of cells. They also undergo development, which involves changes and maturation over time.
4. Energy utilization: Living organisms require energy to carry out vital processes, such as metabolism, movement, and maintenance of homeostasis.
5. Response to stimuli: Living things can respond to the environment around them, including detecting and responding to changes in their surroundings.
6. Homeostasis: Organisms have mechanisms to maintain a stable internal environment, even in the face of external changes.
7. Evolution: Living things inherit traits from previous generations and can undergo genetic changes over time through the process of evolution.
Now let's analyze the objects from the given list:
- "d" and "a" are symbols or letters but are not typically considered living things.
- Assuming the "d" and "a" signify some specific items, we would need further details to determine if they meet the criteria for being a living organism.
Without additional information, it is not possible to definitively identify which object in the given list is a living thing.
