From the description given in the question it is clear that Maurice’s understanding of the association between his father’s keys opening the lock and his father’s appearance is a form of classical conditioning. Classical conditioning is <em>a learning process that occurred when an organism associates a neutral stimulus with an unconditioned response, due to the presence of an unconditioned stimulus. </em>
It can be said that the sound of the key is the neutral stimulus, and the unconditioned stimulus is Maurice’s father appearance, while the unconditioned response is his happiness at seeing his father. Because Maurice has associated the sound of the key with his father’s appearance, his behavior changed even when the neutral stimulus appears, because he anticipates that the unconditioned response would appear afterwards.
The correct answer is that Mayan writing was in the form of images.
<em>A historian can infer about the Maya from the codex pages that Mayan writing was in the form of images.
</em>
A codex is a scientific Mayan manuscript. The Maya codices are folding books dated from the pre-Columbian Maya civilization. The written style or images on the codex are formally known as a Maya hieroglyphic script. It is written on Mesoamerican paper taken from the wild fig tree named by the Mayas, Huun. The images on the codes and the many inscriptions on stone monuments called stelae relate the history, life, and culture of the Maya civilization.
The answer is the last one :)
The correct answer should be B. It has dry soil
The country has 7 different soil types and all belong to the floodplain soils group. This is not odd considering how much water it is exposed to in one way or another, whether through humid air, rivers and oceans, or monsoons and similar precipitation.
