Final answer:
An Institutional Animal Care and Use Committee (IACUC) must review animal research proposals, and it should include administrators, scientists, veterinarians, and community members for a diverse and ethical evaluation process.
Step-by-step explanation:
The committee responsible for reviewing proposals for animal research is the Institutional Animal Care and Use Committee (IACUC). According to the text, the IACUC should comprise a mix of individuals including institutional administrators, scientists, veterinarians, and community members. This diverse group ensures that animal research projects are conducted with the utmost humane treatment and that the guidelines, such as the NIH guidelines and the AWA standards, are being followed. The inclusion of at least one person with no ties to the institution, namely a concerned citizen, is critical to maintain objectivity and public trust in the research process. This setup allows for a holistic review of animal research proposals to minimize pain and distress to animal subjects and ensure ethical standards are upheld.
