<u>Answer:</u>
<em>Cluster of neurons cell bodies in the thalamus is called nucleus.
</em>
<u>Explanation:</u>
Nuclei are present all various points in the central nervous system and are connected to each other through various tracts. Thalamus is a part of the brain and contains different type of nuclei.
<em>They are relay nuclei, association thalami nuclei and non-specific nuclei.
</em>
Association thalami nuclei receives the highest input from the cerebral cortex. Non-specific nuclei plays a significant role in regulating sleep and wake cycles.
Answer:
The main components of the cytoplasm are cytosol (a gel-like substance), the organelles (the cell's internal sub-structures), and various cytoplasmic inclusions. The cytoplasm is about 80% water and usually colorless.
Answer:
The correct answer is -
Thymine: 20%
Guanine: 30%
Cytosine: 30%
Explanation:
According to Chargaff's rule which states that the purine residues are equal to the pyrimidines residue in DNA sample which means A+G = T+C where A is adenine, G is guanine, C is cytosine and T is thymine. It is also known that A is always equal to T and C is equal to G.
So, A+G+T+C = 100
20+20+G+C
100-40 = G+C
60= G+C
as we know G is equal to C similarly A is equal to T
Thus, G = C= 30%
A= T= 20%
