The benefit of using a model is that : ( B ) provides a visual guide for abstract concepts
<h3>Definition of model</h3>
Models helps with the visualization of concepts or objects which cannot be easily seen or felt, It helps with the communication of ideas and predictions by scientists. Models represents abstract concepts which cannot be explicitly explained without the aid of a model.
Hence we can conclude that the benefit of using a model is that it provides a visual guide for abstract concepts.

Answer:
In the water cycle, evaporation occurs when sunlight warms the surface of the water. The heat from the sun makes the water molecules move faster and faster, until they move so fast they escape as a gas. ... When it is cool enough, the water vapor condenses and returns to liquid water.
Answer:
B
Explanation:
Light travels through medium but is fastest through vacuum, so C is wrong, and A is wrong. B is the correct answer.
Answer:
See the answer below
Explanation:
1. The data from the experiment shows that <u>as the percentage of salt in the solution used to water the plants increased, the growth rate of the plants decreased</u>. As the percentage increased from A to D, the change between the average initial and the final heights decreased, meaning that an increase in the percentage of the salt in the solution used to water the plants had a negative impact on the growth rates of the plants.
2. Due to the solutions used to water the plants in groups E and F being more concentrated (hypertonic) to that of the cell sap of the plant, <u>water molecules diffused out of the cell sap to the ambient solution</u>. As time goes by, the plants lose too much water, become wilted, and died off eventually. Instead of water molecules to keep diffusing into the plants in order for them to grow, the reverse was occurring and this led to their death.
