The results of harlow's experiment were overwhelming with an average infant monkey spending hour(s) per day on the cloth mother and hour(s) per day on the wire mother

Harlow Harlow established the nature of affection by experimenting on infant monkeys responses to compare the influence of nursing from the influence of contact comfort. To study this, he compared a wire mother who provided food, and a cloth mother who did not provide food. The infant monkeys preferred contact comfort and spent more time with the cloth mother than the wire mother.

i think its control and coordinate because im pretty sure thats what tissue does and the joints are what control movement and then your skeletal/ bones provides portection. hope that .

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
