Which characteristics of life does a creek have?
A. none
B. able to reproduce
C. maintains homeostasis
D. made of cells
The correct answer is:
C. maintains homeostasis
Out of the given options, a creek would have the characteristic of maintaining homeostasis (option C).
Homeostasis refers to the ability of an organism or system to regulate and maintain a stable internal environment despite changing external conditions. In the case of a creek, it maintains homeostasis by continuously flowing and maintaining a certain temperature, pH level, and oxygen levels, among other factors. However, a creek does not possess the abilities to reproduce (option B) or be made of cells (option D). Therefore, option C - maintains homeostasis - is the correct answer.
To determine the characteristics of life that a creek has, let's go through each option:
A. None: This means that a creek does not possess any characteristics of life. This option is unlikely because a creek is a living ecosystem with various organisms.
B. Able to reproduce: A creek itself cannot reproduce. However, the organisms living within the creek, such as fish, plants, and microorganisms, have the ability to reproduce and contribute to the overall life cycle.
C. Maintains homeostasis: Homeostasis refers to the ability of an organism or system to regulate and maintain a stable internal environment. While a creek doesn't have the same level of homeostasis as individual organisms, it does have certain mechanisms to maintain equilibrium. For example, the flow of water, interactions between living organisms, and the cycling of nutrients help to sustain the balance within the creek ecosystem.
D. Made of cells: A creek is not made up of cells, but it contains countless organisms that are composed of cells. These cells are responsible for the growth, function, and reproduction of the living organisms in the creek.
Based on these explanations, the correct answer would be B. Able to reproduce, C. Maintains homeostasis, and D. Made of cells.
