☐ A decrease in Species A and B would probably cause a decrease in Species E
Species F is a decomposer.
A decline in Species C would decrease competition in Species D and E.
A decline in Species C would, via bottom-up control, regulate Species A.
A decrease in Species A might not result in a long-term decline of Species C
because of functional redundancy.

- Renota, a 51-year-old Slavic woman, lived in Romania with her family on a pig farm. She routinely slaughtered pigs and cooked pork for family meals. She had a wide variety of recipes that called for pork. A few days after preparing one of her famous pork dishes, Renota experi- enced diarrhea, abdominal pain, and chronic indigestion. She went to her family physician and explained her symp- toms to him. The physician, who knew the family well and was familiar with the family business, immediately sus- pected a bacterial or parasitic infection. A stool sample for routine bacterial culture and 0&P study was collected from Renota and submitted to the local diagnostic laboratory. Routine processing procedures were conducted on the stool sample. Gross examination of the stool revealed a portion of the infecting worm (Fig. A). An egg, measuring 36 by 25 um (Fig. B), was seen on the permanent 0&P slide. No intestinal bacterial pathogens were isolated. Questions and Issues for…arrow_forwardWhat thoughts after reading this: "The cases of Henrietta Lacks and the Tuskegee Syphilis Experiment call attention to ethical violations in medical research, particularly involving underrepresented groups. Both instances raise important issues around informed consent, exploitation, and the responsibility of researchers. Biomedical ethics is grounded in principles like autonomy, beneficence, and justice. In both the Lacks case and the Tuskegee study, these principles were ignored. Henrietta Lacks’ cells were taken without her consent, and the men in the Tuskegee study were denied treatment without their knowledge. These failures in ethical oversight have caused lasting harm to the trust marginalized communities have in the medical system. Institutional Review Boards (IRBs) are designed to ensure ethical standards in research by requiring informed consent and protecting participants from harm. However, in Lacks’ case and the Tuskegee study, no such protections were in place. These…arrow_forwardWhat are your thoughts on this subject: "The story of Henrietta Lacks highlights critical issues in biomedical ethics, researcher responsibility, and the exploitation of marginalized communities. Henrietta, an African American woman, had her cells taken without consent in 1951 during her treatment for cervical cancer at Johns Hopkins Hospital. These cells, known as HeLa cells, became pivotal in medical research, contributing to the development of vaccines and cancer treatments. However, Henrietta and her family were never informed or compensated for the use of her cells. This violation of informed consent, a core principle of biomedical ethics, mirrors broader patterns of exploitation seen in historical medical studies, such as the Tuskegee Syphilis Study, where African American men were used in experiments without their consent or proper treatment. These unethical practices were often justified by racist and paternalistic attitudes, perpetuating a deep mistrust in medical…arrow_forward
