Answer:
A wider range of sexual practices
Explanation:
The major difference between the bonobos and the chimpanzees are that while the chimpanzees are ruled by men who are occasionally violent, the bonobos are matriarchal.
As a result of this, the bonobos engage in a wider range of sexual practises and playful behaviours among themselves.
Answer: reliable but not valid
Explanation: Reliability does not translate to validity. This can be proved using the behavior of John's oven which has exhibited consistency in functionality and performance which defines that the readings and output are reliable. However, even though John's oven has exhibited constant output reliability due to its ability to consistently give similar readings or performance levels for about a month, the consistent performance which has been showcased by the oven seems to be faulty as food seem to get burnt regularly. This consistent output or performance level lacks validity as the temperature Guage incorrectly shows temperature which is 50 degrees cooler than the actual oven temperature.
Answer:
b) electrons jump onto or off the neutral ball when a charged object comes close
Explanation:
What causes a pithball to move is when "electrons jump onto or off the neutral ball when a charged object comes close".
The pithball electroscope is actually used to test if a body is charged or not. When a charged body is brought near the pithball, the ball moves. The movement of that charged body reveal that there are electrons it is carrying.
The pithball can actually be charged. It is charged by touching a charged object to it. This leads to some of the charges on the surface of the charged object moving to the surface of the ball. The pith-ball electroscope was invented by John Canton, a British schoolmaster and physicist in 1754.
