Which field studies moral decisions related to advances in biology, medicine, and technology?

The correct answer, bioethics, encompasses the study of moral decisions and ethical considerations that arise in the context of biological research, medical practice, and technological advancements. This field addresses a range of complex issues, such as patient rights, consent, the implications of genetic engineering, and the ethical treatment of different species in research contexts. Bioethics is critical as it helps guide healthcare professionals, researchers, and policymakers in making responsible and informed choices that align with ethical standards and societal values.

Biomedical ethics is a related field that specifically focuses on ethical issues within medicine and healthcare, which is a subset of bioethics. While genetics deals primarily with hereditary factors and the science of genes, ecological ethics focuses on environmental issues and the moral relationship between humans and their natural environment. Therefore, while the other options represent relevant disciplines, only bioethics comprehensively covers the full scope of moral decisions tied to advances in biology, medicine, and technology.
