The major pathway of communication between the right and left hemispheres is the:.
Sergeu [11.5K]

The major pathway of communication between the right and left hemisphere is the corpus callosum.

  • The cerebrum is the recognizable gray covering of the human brain, appearing to comprise the majority of its mass.
  • The cerebral cortex is the wrinkly area; the remainder of the anatomy is hidden behind that layer.
  • The longitudinal fissure, which is a significant gap between the two sides of the cerebrum, exists.
  • It divides the brain into right and left cerebral hemispheres, which are two independent parts.
  • The main channel for communication between the two hemispheres of the cerebral cortex is provided by the white matter of the corpus callosum, which is located deep inside the cerebrum.

Why can't astronomers measure the parallax of a star that is a million light years away?
motikmotik

One of the methods used widely to calculate the distance of nearby or closer objects in astronomy is Parallax. The distance of the stars are usually expressed in light years but the unit of distance is parsec or parallax second.  

                                        1 Parsec = 3.26 light years

Astronomers are not able to measure the parallax of a star that is a million light years away because the star is too far and the distance with which the start appears to move is too less to be calculated accurately.

Therefore the three genetic materials from different parents (mitochondria from donor mother, DNA from biological mother and DNA from biological father) would be present in the baby. Somatic nucleus transfer is the medical procedure used when the biological mother has mitochondria disorder which she would not wish to pass to her offsprings (which are inherited maternally).

what is the maximum number of amino acids that can be specified by a codon consisting of a sequence of four bases
vichka [17]

Answer:

64.

Explanation:

It is 64 because there are 20 amino acids with four bases ( A,T,C and G).

and genetic code can be read in triplets and also the four bases can occupy the positions. Eachh amino acid can be coded by the triplet codons. A triplet codon shows three nucleotides of the mRNA template that can code for amino acid

Therefore the number of codons is 4×4×4= 64.
