A scientist sets up terrariums in a laboratory and observes the growth of lizards in each terrarium. Which of the following observations could be used as evidence that the amount of space in an environment can affect an animal's growth?
which choices?
One possible observation that could be used as evidence that the amount of space in an environment can affect an animal's growth is:
1. The lizards in the smaller terrariums exhibit stunted growth compared to those in the larger terrariums.
By comparing the growth of lizards in different-sized terrariums, the scientist can assess whether limited space has an impact on the growth of the animals. If the lizards in smaller terrariums show slower or stunted growth compared to those in larger terrariums, it suggests that the amount of space available can affect their growth.
To determine which of the following observations could be used as evidence that the amount of space in an environment can affect an animal's growth, we first need to understand the experimental design and the concept being tested. The scientist has set up terrariums, which are controlled environments, in a laboratory. The scientist is observing the growth of lizards in each terrarium. The aim of the experiment is to investigate if the amount of space in the terrarium affects the lizards' growth.
To find the observation that could be used as evidence, we need to consider how different amounts of space would impact the lizards' growth.
Observations that suggest a relationship between space and growth may include:
1. Lizards in larger terrariums exhibit faster growth compared to lizards in smaller terrariums.
- This observation would indicate that more space leads to increased growth, suggesting a positive correlation between space and growth.
2. Lizards in smaller terrariums exhibit stunted growth compared to lizards in larger terrariums.
- This observation would suggest that limited space hinders growth, indicating a negative correlation between space and growth.
3. Lizards in crowded terrariums display slower growth rates compared to lizards in less crowded terrariums.
- This observation would imply that increased competition for space in crowded conditions can impede growth, indicating a negative correlation between space and growth.
Therefore, observations 1, 2, and 3 could all potentially be used as evidence to support the notion that the amount of space in an environment can affect an animal's growth. The actual outcome of the experiment and the specific observations recorded will ultimately determine the validity of this claim.
