Answer:
point mutation missense mutation silent mutation non sense mutation
Explanation:
point mutation it change one base of DNA in this case nucleotide substitution occur like sickle cell missense mutation in this case replacement of one nucleotide nonsense mutation cause the replacement of codon silent mutation does not change the sequence of protein because of new triplets codes for the same amino acid
The Earth's lithosphere is 100km while astehnosphere is 660km so this statement stands true.
Other statements are false like Earth’s mantle is thinner than its oceanic crust as Earth’s mantle is around 3k km while its oceanic crust is just 5km.
Also, Earth’s outer core is thicker than its mantle and Earth’s continental crust is thicker than its lithosphere is false as well.
If this is true or false than it is FALSE
In most mammals, hemoglobin consists of 4 distinct subunits. These subunits consist of an aminoacid chain (aminoacids are the building blocks of proteins) and a heme group. 2 of the subunits have a protein chain with a-structure and 2 have a protein chain with beta structure. The heme groups give hemoglobin and thus blood its red color. Each of these groups has a positively charged iron ion in its core. Iron is necessary so that hemoglobin can bind oxygen and transfer it through the blood flow to the tissues. Given the above exposition, the correct answers are: 4, alpha proteins, heme, iron, oxygen.
Bonus: Hemoglobin is an important example of protein structure since it shows that not only aminoacid order (secondary structure) and configuration of protein chains (tertiary structure) are crucial to the function of a protein; how the multiple chains bind to each other is equally critical (quaternary structure).
