(05.05 MC) Exposing human subjects to experimental manipulations such as high levels of toxins is unethical. We often use model

organisms for this reason. What attributes would you look for in selecting a good model organism for investigating the impact of toxins in humans? A good model organism should be able to be easily maintain in the laboratory, be fast growing, with a fast generation time and be as closely related to humans as possible. Cost is the only consideration in selecting a model organism, since all living things are made of cells anything found will apply to humans. The best choice will must be the very closely related to humans, such as chimps, since anything found in other species will not apply to humans. The most important consideration in selecting a model organism is how the public will feel about doing experiments on that species, so the best choice would generally be a very simple organism like bacteria that people don't care very much about.

Answer:

A good model organism should be able to be easily maintain in the laboratory, be fast growing, with a fast generation time and be as closely related to humans as possible.

Explanation:

The attributes that should be looked for in the selection of good model organism for investigating the impact of toxins in humans include:

  • Easy maintenance: The easier the maintenance of the organism, the better for both the research and the researcher. More can be achieved with less effort as opposed to high maintenance animals.
  • Fast generation time: They should be able to grow and reproduce quickly so as not to prolong the experiment for too long. The lower the regeneration time, the shorter the time required to obtain adequate data for the research.
  • Genetical similarity to humans: A good model organism for humans related study must share some similarities with humans at the genetic level. The more the genetic similarity, the more applicable the outcome of the research on humans.

<em>Hence, a good model organism should be able to be easily maintained in the laboratory, be fast-growing with a fast generation time, and be as closely related to humans as possible.</em>

How many global bleaching events occurred since the year 2000
poizon [28]

Answer:

he summer of 2001–2002 saw a mass bleaching event that was slightly more severe than the 1997–1998 event. The first signs of substantial bleaching were reported in January 2002, with the worst over by April.

In response, GBRMPA implemented the world's most comprehensive survey of coral bleaching in collaboration with AIMS, the Cooperative Research Centre for the Great Barrier Reef (CRC Reef) and the US National Oceanic and Atmospheric Administration (NOAA). Aerial surveys revealed bleaching in 54 per cent of the 641 reefs observed. Nearly 41 per cent of offshore and 72 per cent of inshore reefs had moderate or high levels of bleaching.

Again, reef recovery was generally good, with fewer than five per cent of the reefs suffering high mortality. The worst affected reefs were in the Bowen area where around 70 per cent of corals died.
