Lesions to the medial geniculate of the amygdala block conventional auditory fear conditioning.
Medial geniculate
The medial geniculate body (MGB) is a collection of nuclei that receives heavy input from the IC and acts as a key synaptic junction on the routes that carry data to the cerebral cortex's auditory regions.
One should also think about how the medial geniculate's structure might affect its possible roles as a relay nucleus given the substantial studies on its anatomy. It is not in question that the MGv, which is the lemniscal portion of the MGB, "relays" accurate auditory information to the primary auditory cortex.

The answer to the question stated above is Duplication.
Duplication is one of the chromosomal mutation whereby <span> a segment of chromosome is copied twice, resulting in extra allele.</span><span>
</span>
Chromosomal mutation involves the change in chromosome structure which changes the composition or location allele.
Other chromosomal mutation includes:
<span>Deletion - occurs when a segment of chromosome is broken off and lost. </span>
<span>Inversion - happens when a segment of chromosome is broken off and reattach itself in inverted position.
</span><span>Translocation - takes place when a segment of chromosome is broken off and reattach at different point. </span>
Answer:
Cerebellum
Explanation:
The cerebellum is a region of the brain whose main function is to integrate the sensory and motor pathways. There is a large number of nerve bundles that connect the cerebellum with other brain structures and with the spinal cord. The cerebellum integrates all the information received to specify and control the orders that the cerebral cortex sends to the musculoskeletal system through the motor pathways. It is the regulator of physiological tremor.
The correct answer is: C)Iceland .
The fissure formed in the Iceland is called Silfra. It is a fissure filled with fresh spring water within lake of National Park in Iceland.
It was formed 40 years ago due to the movements of the tectonic plates. The North American and Eurasian plates, separate at about 2 cm per year, and they tear open fissures in the land between them.
Answer:
ribosomes and cell membrane
Explanation:
Prokaryotes are not allow to have nucleus. They have free roaming DNA, so only ribosomes and cell membrane can be both.
