In psychologist Robert Rescorla's classical conditioning experiment, one group of rats experienced a tone just before each of 20

shocks. A second group of rats experienced the same number of tone-shock pairings plus an additional 20 shocks with no tone. Rescorla found that the rats in the first group showed a much stronger conditioned fear response than the rats in the second group. How did Rescorla explain this finding

Answer:

The answer is given below.

Explanation:

Rescorla explain this finding by stating that the tone experienced by the group of rats just before each of 20 shocks was a reliable predictor of the shock for the first group.

The psychologist Robert Rescorla stated in his famous classical conditioning experiment that  2 stimuli does not produce the same level and kind of conditioning.  Conditioning works in a better way, if the conditioned stimulus will act as a reliable signal that projects the appearance of an unconditioned stimulus.

Answer: Sea walnuts are marine invertebrates. They belong to the genus Mnemiopsis.

Explanation:

These animals have stinging tentacles like jelly fish and they often cast up or come to the sea shores where if they come in contact with humans can harm them by stinging.

The barrier if kept along the side of the sea shore and not allowing humans to reach to the shore can help in preventing the harm from these animals. The introduction of the predatory animals in the sea can also help in reducing their population.

The three benefits for removing the sea walnut:

1. The population of other species will increase as sea walnut is an invasive species.

2. The balance of the marine ecosystem can be maintained.

3. Humans can be protected from the harm caused by these animals.

Answer:

Parallel Evolution

Explanation:

It is because only three members are normal while one of them has a rare recessive allele. Due to parallel evolution, the recessive allele will now  become common as the other previously distinguished dominant alleles and now all the traits will be in a uniform equilibrium according to Hardy-Weinberg Theorem.

Answer:

Ok so i will try my best to describe the answers:

1) a convection current is like a boiling pot of soup. the burner heats up the soup on the bottom. hot air always goes up because the molecules become more active, making them space out upward. the hot soup travels up through the center of the pot, and the cold soup up top travels down towards the edges of the pot to replace the hot soup that just moved up. the process keeps on going and going until there is no more heat, or until the burner turns off.

2&3) the sun makes everything warmer, so when the sun touches Earth's surface, it warms up the air around it. as soon as the air warms up, it goes up into the atmosphere, like the pot of soup example. then, cold air from the top moves in to replace the hot air. with so many molecules of air moving at one time, it makes gusts of wind during the movement. when it is really windy, that means that there is a lot of hot air moving up and cold air moving down. when there is no wind, that means that every molecule is where it is supposed to be, not disturbing one another.

I hope this helps :D
