In a DNA molecule, three nucleotides make up a codon. A codon is creates a specific amino acid. Therefore, in order to work this out, we must calculate the number of codons that will not be affected by the mutation. This is done by finding the highest number that is divisible by 3 but less than 85. This can be done by:
85 / 3 = 28.333
So 28 codons will not be affected.
Answer:
d. CT scans of the fossilized skulls of Hobbits suggest they were probably microcephalic modern Homo sapiens.
Explanation:
The work of Falk et al in 2007 compared the CT of microcephalic humans skulls and normal humans skulls, finding the variables that allow them to classified with 100% success. When compared with the skulls of the ‘Hobbits’ of Flores, the size is similar to the microcephalic skulls in humans but the shape features sort it with normal humans skulls. They concluded that the ‘Hobbits’ of Flores are a separate species.
Frost wedging is a type of physical weathering of rock.
Explanation:
Physical or mechanical weathering affects the rock structurally but does not change the chemical composition. Mechanical forces will rub, break or shatter the rock surfaces. Wedging, abrasion, exfoliation are different types of physical weathering.
Water is one of the main sources which alter the structure of the rocks physically.
Frost wedging occurring due to flow of freezing water over the rocks. This frozen water enters the rock through the cracks and crevices on the rock surface, and will expand inside and makes the rocks to crack further and breaks it apart.
