The statement "Ideas may need to be adapted to different audiences" is true when communicating scientific ideas.

When conveying scientific information, it's essential to consider the background, knowledge level, and interests of your audience. A presentation for fellow scientists at a conference, for example, will contain different language, concepts, and depth than an explanation aimed at the general public, schoolchildren, or policymakers. Tailoring the complexity, language, and presentation style to the audience helps ensure that the ideas are understood and appreciated.

The other statements you've mentioned are not accurate:

1. Ideas are not static and rarely change: In reality, scientific ideas are dynamic and often evolve as new research and evidence emerge. Science is a constantly progressing field where theories and understandings are updated in the light of new data.

2. Ideas never need to be adapted to different audiences: As mentioned above, adaptation is crucial for effective communication across different audiences.

3. Ideas are harder to understand when they're explained clearly and concisely: On the contrary, clarity and conciseness are key principles for effective communication. When complex ideas are broken down and presented in a clear and straightforward manner, they are generally easier for the audience to understand.
