Answer: B. dissection
Autopsy or postmortem is a medical examination of human body that is performed to know the cause, manner and duration since death. The autopsy involves complete examination of the body. The external examination gives indication of situation of the body : number of injury, color changes due to the affect of poisons. Internal examination gives indication of condition of organ in the body of deceased. For a complete internal examination dissection is required. Autopsy is complete when all four cavities like cranial, thoracic, abdominal and pelvic are open through dissection, which allows the assessment of organs present in these cavities. Opening of the intestinal cavity will give a way to assess the intestine, which can be dissected to know the contents present in it.
Answer:
Promoter is located upstream and terminator is located downstream relative to the transcription start site.
Explanation:
Transcription start site is the site from where the transcription starts which is denoted by +1. The sequence of nucleotides which is present backword to them called upstream sequence and nucleotide sequence which is present in the forward direction of transcription start site are called downstream sequence.
Promoter sequences are present upstream to the transcription start site and are denoted with a minus sign and terminator sequence is present downstream to the transcription start site.
Distantly related organisms may be similar if they live in Similar environments
This is false. Organisms may play several important roles in an ecosystem. Consider for example and ocean shore environment occupied by a particular species of crab. The crabs are scavengers and eat any organic matter they encounter. They therefore play an important role in the cycling of nutrients in the ecosystem. The crabs are however also an important source of food for a range of other species occupying the same habitat, including octopi, certain fishes and sea otters. Therefore, the crabs are an important part of the food web in the ecosystem. Many species similarly occupy multiple important roles in an ecosystem.
