The correct answer is B) not asking subjects to agree to participate without first informing them of the nature of the study and possible risks and benefits.
Explanation:
Clinical trials often involve testing treatments such as new vaccines, medicines or therapies. Moreover, these can have different positive or negative effects on participants of the trial. Due to this, one of the basic principles to follow ethical standards for this type of medical research is being completely honest with participants, which includes explaining to them the purpose of the trial, possible risk and also positive benefits.
This is important because in this way participants can make an informed decision on whether to participate or not in the trial which is part of consent. Thus, ethical standards for clinical trials include "not asking subjects to agree to participate without first informing them of the nature of the study and possible risks and benefits".
Answer:
If the greater and/lesser sciatic notches of the ilium were abnormally small and narrow, it has less modification effects on males but can considerably caused difficulties in child deliveries in females.
This is explained below
Explanation:
In cases if the greater sciatic notches of the ilium are unusually small and narrow, it will not cause any modifications in males. However, this is not the cases in females in a way that if the greater sciatic notches of the ilium were unusually small and narrow, then it would become difficult for the baby to pass through the pelvis at the time of delivery, thus resulting in complications during childbirth.
Due to this, the normal delivery would get complicated resulting in breathing complications and may even be fatal for the child.
The large, inverted U-shaped depression found in the posterior margin of the lower ilium is known as the greater sciatic notch. The marginally bent posterior margin of the ischium above the ischial tuberosity is the lesser sciatic notch. The body protrusion distinguishing the greater sciatic notch and the lesser sciatic notch is the ischial spine.
The greater sciatic notch of the male hip bone is deeper and narrower in comparison to the broader notch of the females. As the female pelvis is amended for childbirth, it is broader in comparison to the male pelvis, as proved by the distance between the anterior superior iliac spines.
