Question
A researcher wants to investigate the impact of salt water on the growth of plants. Which of the following would be the best hypothesis for this experiment?(1 point)
Responses
If salt water is used to water plants, then the plants will not grow as tall as those watered with tap water.
If salt water is used to water plants, then the plants will not grow as tall as those watered with tap water.
I think salt water will help plants grow taller.
I think salt water will help plants grow taller.
I will add salt water to plants and observe how they grow.
I will add salt water to plants and observe how they grow.
Plants need water to grow, and they should also be exposed to sunlight.
Plants need water to grow, and they should also be exposed to sunlight.
so the answers to the quick check is
1.B if acid
2. D is T and T

The best hypothesis for this experiment is:
If salt water is used to water plants, then the plants will not grow as tall as those watered with tap water.
Based on the response options provided, the correct answers for the quick check are:
1. B - If salt water is used to water plants, then the plants will not grow as tall as those watered with tap water.
2. D - I will add salt water to plants and observe how they grow.
3. A - Plants need water to grow, and they should also be exposed to sunlight.
Yes, that is the correct answer for the first question. The hypothesis states that if salt water is used to water plants, then the plants will not grow as tall as those watered with tap water.
The best hypothesis for investigating the impact of salt water on the growth of plants is:
"If salt water is used to water plants, then the plants will not grow as tall as those watered with tap water."
The best hypothesis for this experiment would be: "If salt water is used to water plants, then the plants will not grow as tall as those watered with tap water."
This hypothesis follows the basic structure of a scientific hypothesis, which includes an independent variable (salt water), a dependent variable (plant growth), and a predicted outcome (plants will not grow as tall as those watered with tap water).
To arrive at this answer, you need to understand the elements of a scientific hypothesis and apply them to the given options. A scientific hypothesis is a statement that proposes a possible explanation to a scientific question or problem. It is usually based on observations, prior knowledge, or logical reasoning. In this case, the question is about the impact of salt water on plant growth. Therefore, the hypothesis should specifically address this relationship.
Option 1 correctly states the independent variable (salt water), the dependent variable (plant growth), and predicts the outcome (plants will not grow as tall as those watered with tap water). This option is the most specific and appropriate hypothesis for the given experiment.
