Answer: Sensory mechanisms are responsible for detecting the external stimuli present in the environment.

The sensory mechanisms help people to observe things around them through eyes, they can hear the sounds through their ears, they can feel the insect creeping on their skin by touch sensory mechanism, they can taste food which they cook through taste or gustatory receptors present on tongue and other parts of mouth cavity.
Our actions is affected by physical environment.
The correct answer is - 1,180 km.
North America and Europe move away from one another, though the two plates, the North American and Eurasian are merging together on the other side. Since the rate of moving away is 2 cm per year, and the current distance is 1,184 km between North America and Europe, the distance between them 200,000 years ago was 1,180 km.
To get to the result we only need to multiply the number of years with the annual movement
2 x 200,000 = 400,000
Than divide the result with 100,000, as that is how much cm are in one km
400,000 / 100,000 = 4
And we get 4 km, in this case 4 km less, thus the distance between the two, 200,000 years ago, was 1,180 km.
