Answer:
Umbilical cord
Explanation:
Allantois is a hollow sac like structure. Its primary role is to eliminate liquid waste from the fetus and help in exchange of gases. Amniote is the group of organisms which contain allantois, amnion and chorion. Reptiles, birds and mammals are part of this group.
In mammals, allantois develops into umbilical cord. Umbilical cord is present between the fetus and the placenta. Human umbilical cord has two arteries and one vein. The vein brings nutrient rich, oxygenated blood from the placenta to fetus. The arteries brings back nutrient depleted, deoxygenated blood to placenta.
According to the article, punishing behaviors is less effective and results in less accurate learning than reinforcement, as shown in option D.
We can arrive at this answer because:
- Thorndike proved that punishing behavior in situations of stress is less effective in learning.
- He proved this by watching cats trying to escape puzzle boxes.
- When they became stressed, the cats screamed, bit, scratched and were punished without getting out of the box.
- This added to the stress and made them take even longer to escape.
- However, as they began to think about how they could get out of the box, the cats were receiving positive rewards and reinforcement, which was gratifying and encouraged them to find their way out.
In this case, Thorndike realized that punishment was not very effective in a stressful situation, at least when compared to reinforcement.
