The best known Hawthorne study was that of lighting-level effects by Roethlisberger and Dickson (1939). In this study employees were taken to a special room where lighting levels were varied from day to day to see how performance would be affected. They found that

They found that workers were more responsive to social factors such as the people they worked with and the amount of interest their manager had in their work.

Explanation:

The Hawthorne study involving lighting level effects was carried out to  determine motivating factors behind productivity at work. Four studies were used in this experiment;

The study therefore, didn't yield results on productivity in response to lighting. It was then seen that social factors, were the biggest motivator in job performance, mainly how much attention was being paid to individual employees. Being knowingly watched, was seen to have a positive effect on employee productivity.

answer; the above statement is (false);

the answer is "meiosis ii in the mother".

the procedure of meiosis includes two divisions of the hereditary material. the main division is known as the decrease division – or meiosis i – on the grounds that it lessens the quantity of chromosomes from 46 chromosomes or 2n to 23 chromosomes or (n depicts a solitary chromosome set). in people, the decrease division results in two sperm cells each with 23 chromosomes or an egg cell with 23 chromosomes and one disposed of polar body. the second division – or meiosis ii – is called equational division. the two sperm cells split again creating four sperm cells, each with 23 or n chromosomes. in oogenesis, the egg cell and polar body partition to shape the ovum and two extra polar bodies. along these lines, the posterity are guaranteed to get one portion of the chromosomes from the mother and one half from the dad.
