Answer:
Eleanor Gibson was an American experimental psychologist
Explanation:
Eleanor Gibson was an American experimental psychologist whose famous works includes her study of depth perception theory on how children perceive their environment.
Eleanor stumbled on the virtual cliff discovery in one of her experiment that involves raising rats in the dark on a virtual cliff made of a sheet of glass with patterned paper, an experiment initially meant to get more use out of dark-reared rats. The dark-reared having presumed to have lost perception in the dark, was expected to walk indiscriminately on the near and far sides of the cliff. However, to her surprise the dark-reared rats chose the near side, and consistently avoided the glass-covered drop-off portion of the cliff. This shows the dark-reared rats which have not had any previous experience about depth could perceive depth. Gibson later on tested this experience on other animals. She also tested it on human babies using the presence of the mother to initiate crawling. The babies were also found to perceive depth on the cliff without a prior knowledge or experience of such.

Maybe because they are bringing in quite a bit of money and don't have to spend time fighting anybody, so they can afford to spend time trying to solve world problems.
Explanation:
There is found a mutation in G5W parents during the gamete formation created X-linked dominant disease allele. As the expression of the allele determines the allele that dominant or recessive. Because sometimes the allele becomes complete even then it is incomplete. In many cases, these alleles occur together or express at the same time that is called co dominance. The X-linked inheritance works differently with male and female because the male has XY chromosome and female has only XX chromosome. So a man has chances their son 50% but daughter has more or 99% chances to be inherited by the disease. Females only pass their X chromosome to each son or daughter so the chances from a female dominant inheritance 50% chances of X-linked disease.
