Cheetahs are large wild cats native to Africa and the Middle East. Their natural populations have been declining steadily. Genetic analysis indicates that surviving cheetahs have almost identical genetic makeups. This lack of variation has led many scientists to conclude that the species is essentially extinct. That is, numbers are not expected to recover and restore wild populations to their former levels. 9. Suggest a logical explanation of this conclusion based on your understanding of interaction between genes and the environment. Cheetahs are large wild cats native to Africa and the Middle East.

Injury related accidents are common in industrial workplaces. To reduce the risk of accidents a number of extra safety features can be engineered. Consider a workbench that has a mechanical guard and an electric saw, as shown below. Mechanical guard 5V -Electric saw Unknown logic gate Saw switch The mechanical guard is installed to prevent any injury to the human operator. Let the electric switch ON state be represented by logical 1, and the state of the mechanical guard being down be represented by logical 1. Only if the guard is down and the electric saw switch is ON, should the electric saw turn ON. Prepare a truth table for the states of the electric saw. Let logical 1 represent the electric saw being ON. Mechanical guard Saw switch Electric saw 0 0 0 1 1 0 1 1 A single gate can be used to implement the logic of the truth table above.
