An automatic security camera must operate as follows when arn intrusion occurs: 1. if the ambient light level is greater than 20mw/cm2, the shutter is activated. 2. if the ambient light is less than 20mw/cm2 a light source is triggered. 3. when the source lighting reaches 20mw/cm2, the shutter is triggered. design the system and signal conditioning using the following assumptions: a. the shutter and light source are triggered by ttl logic high signals. b. a cds cell with characteristics given in figure 6.9 is used to monitor ambient light level c. a photodiode with the characteristics given in figure 6.16b will be used to measure light intensity after the light source is triggered. explain why the cds cell could not be used here also

In the nineteenth century, gregor mendel first determined some basic rules of genetics that have been observed throughout all types of life. no observations have disproved these basic rules of genetics. charles darwin developed the idea of biological evolution around the same time, but he was unaware of mendel’s discoveries in genetics. over a century later, darwin’s idea of evolution was modified in order to incorporate mendel’s rules of genetics along with the other evidence that darwin had used. what is most likely the relationship between mendel’s rules of genetics and darwin’s idea of biological evolution? a.)mendel’s genetics states laws that are now part of the theory of biological evolution.b.)biological evolution states laws that are part of mendel’s theory of genetics.c.)mendel’s genetics replaced darwin’s entire concept of biological evolution.d.)biological evolution is a law that explains why all genetics exist.
