The characteristic that helps distinguish deuterostomes from protostomes is (a) embryological origin of the mouth from blastopore.

Deuterostomes are the organisms in which the mouth develops from the opening other than the blastopore (the first opening). In deuterostomes the anus forms from the blastopore. The example of deuterostomes is: vertebrates (and thus humans), sea stars, and crinoids.

Protostomes are the organisms in which the mouth develops from the blastopore. Their anus is formed after the formation of mouth. Examples are:  arthropods, molluscs, annelids, flatworms and nematodes. Both protostomes and deuterostomes have a common ancestor called Ediacaran, a worm-like aquatic animal.

Which of the following experiments would be considered unethical?
sveticcg [70]

Answer:

C. Taking blood samples from patients for research purposes

without consent

Explanation:

Generally, providers may not render medical services without the patient’s consent, unless performance of emergency, lifesaving care is necessary. Taking samples from a patient is a type of medical service; thus, state consent laws apply. In addition, providers may not disclose PHI without patient authorization.

It depends on the definition of unethical being used, however I think I am right. I'm in AP bio currently. Let me know what the answer is :)
