Checking for contents of the intestinal tract would be done during which phase of the autopsy?

a. external examination
b. dissection
c. post-autopsy
d. internal examination

The correct answer is option (D) internal examination.

Autopsy or the post-mortem examination is a surgical procedure involving the detailed examination of a corpse by dissection. It is done to evaluate the cause, manner and the mode of death.

Basically there are three steps in the process of autopsy. They are-

1. External examination- It involves the collection of the external evidence which includes the kind of clothes, position of the body or any external material on the external surface of the body. The body is then photographed, cleaned, weighed and a general description of the body is noted.

2. Internal examination- Many incisions are made on the body to inspect the internal organs of the body by dissection. It exposes the body parts like the lungs, heart, stomach and the intestinal contents and the brain. The organs are removed and studied to evaluate the cause of death.

3. Reconstitution of the body- The body cavity is lined with cotton, wool and other organs are placed in a plastic bag to prevent the leakage and added back to the body and sewn back.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
