Frances puts a hungry rat into an experimental chamber. whenever the rat presses a lever, food falls into a tray. in about 30 mi

nutes, the rat is pressing the lever steadily. frances returns the rat to the training cage for one hour a day every day until the rat produces young. frances then trains one of this rat's offspring in the same manner as its mother and repeats this procedure for generation after generation. you predict that when the twelfth generation rat is put into the training cage, it will press the lever steadily in about ____.

It'll still be about 30 minutes, being able to complete a specific task that you must be taught first isn't hereditary, so it'd be about the same. 

For instance, if a woman is an amazing pianist, and she has a daughter, would the daughter also be a professional pianist automatically? No, she'd have to be taught how to play first. Sure, certain genetic traits that may help play piano more easily may have a say in it, i.e., longer fingers, but the talent of playing piano isn't passed on from mother to child through reproduction.

Processes such as changes in orbital geometry or volcanic eruptions have clearly affected climate in the past, and these explain
docker41 [41]

Answer:

TRUE

Explanation:

There has been a constant increase in the earth's global surface temperature. This global rise in temperature is due to the increasing number of volcanic eruptions on earth's surface, changes in the orbital geometry as well as due to the introduction of the industrial revolution, that has been taking place on earth for the last 200 years.

The eruption of volcanoes leads to the release of a large number of pyroclastic materials and greenhouse gases and volcanic gases such as CO₂, SO₂, H₂O, H₂S and many other gases, which is harmful to the atmosphere. This leads to an increasing amount of temperature, resulting in the melting of the glaciers in the polar region.

Over this long time, plate motions have rapidly taken place, due to which the volcanoes were formed and erupted near the convergent and the divergent plate boundaries.

Thus, the above-given statement is true.
