A third-grader decided to breed guinea pigs for her school science project. She went to a pet store and bought a male with smoot
h black fur and a female with rough white fur. She wanted to study the inheritance of those features and was sorry to see that the first litter of eight contained only rough black animals. To her disappointment, the second litter from those same parents contained seven rough black animals. Soon the first litter had begun to produce F2 offspring, and they showed a variety of coat types. Before long, the child had 125 F2 guinea pigs. Eight of them had smooth white coats, 25 had smooth black coats, 23 were rough and white, and 69 were rough and black. a. How are the coat color and texture characteristics inherited? What evidence supports your conclusions?
In terms of communication, information is expressed either as the content of a message or through direct or indirect observation. That which is perceived can be construed as a message in its own right, and in that sense, information is always conveyed as the content of a message.
Information can be encoded into various forms for transmission and interpretation (for example, information may be encoded into a sequence of signs, or transmitted via a signal). It can also be encrypted for safe storage and communication.
Solar waves with wavelengths between 160 and 400 nanometers are known as ultraviolet rays and carry higher levels of energy than sunlight. Solar waves with wavelengths between 780 and 1,500 nanometers are known as infrared rays and carry lower levels of energy than sunlight.
