Explanation:
Macromolecules are molecules of large number of atoms usually with a diameter ranging from about 100 to 10,000 angstroms.
The area marked by A in the figure is the cerebral cortex/cerebral mantle.
<h3><u>Explanation:</u></h3>
The cerebral cortex is known as the surface of the brain. It is the outer layer of the cerebrum dividing it into two hemispheres. There a numerous peaks and grooves in this layer called as gyri and sulci.
The cerebral cortex is the largest point of neural intergration in the central nervous system. It is essential for the actions like "attention, perception, awareness, thought, memory, language, and consciousness".
Answer:
The 4 codons that code for Alanine are :-
GCU ; GCC ; GCA ; GCG ;;
codon for Valine :-
GUU ; GUC ; GUA ; GUG
Part A. Total number of possible mutations are 36.
GCU
GCU --> GCC , GCA , GCG
GCU --> GUU , GAU , GGU
GCU --> UCU , CCU , ACU
GCC
GCC --> GCU , GCA , GCG
GCC --> GUC , GAC , GGC
GCC --> UCC , CCC , ACC
GCA
GCA --> GCU , GCC , GCG
GCA --> GUA , GAA , GGA
GCA --> UCA , CCA , ACA
GCG
GCG --> GCU , GCC , GCA
GCG --> GUG , GAG , GGG
GCG --> UCG , CCG , ACG
Part B. Silent mutations occur when the last base of the codon is substituted with other bases.
Thus, the Total number of silent mutations are 12.
Part C. Conservative mutations occur when the second base of the codon is substituted to a "U".
Thus, the Total number of conservative mutations is 4.
Answer:
3km per hour
12 ÷ 4 = 3
divide the speed by the hours and get your answer
