they check their eyes with a piece of equipment called a scethascope, this shows each particle, if one one is a round shape instead of hexagon you know the creature is colour blind.
Not all animals are colourblind. However, certain scientists have done specific research and testing on it and have finally came to a conclusion with scientific proof.
No.
Colourblind - Darius Campbell song - was created on 2002-07-29.
It informs other scientists of its existence, and makes it easier for other scientists to find the relationships between animals
yes mum
Im not sure exactly what you mean but if you mean can a colourblind person see colours of course we can we just see them differently and sometimes more obscurely. I personally find it annoying when people who know I'm colourblind ask me stuff like that. If you mean do colourblind and non colourblind people see colours differently; yes. Colourblindness is caused by a slight "difference from the normal" of the yellow spot (cluster of photosensitive cells that allow colours to be distinguished)
They survey (land) with computers to take notes
Scientists first find out why the animal is getting endangered. Then, they usually start a campaign, such as "Help Save The (animal)!" The scientists can work with authorities to ban poaching from the area that the endangered animal lives in, or they can take in some of the animals and breed them. Scientists also tell pro. breeders about what they want.
Scientists can use satellite images to asses the conservation status of the endangered animals. They are then able to use the results to find which species are threatened and determine the priority for future protection.
The cast of Colourblind - 2011 includes: Angela Canalese as Anne - Marie Dominik Witkop as Opthalmologist
Scientists
Scientists often use observation to find out which animals use internal or external fertilization. If direct observation isn't possible, they may look to closely related species to make an educated guess about the lesser-understood species' fertilization method.
