Eva8 [605]

Answer: A change in the sequence of DNA bases--> Joining amino acids in sequence --> Appearance of characteristics

Explanation:

A mutation is a permanent shift or change from the normal DNA sequence that makes up a gene and affect traits which makes the sequence becomes different from what is commonly found in people. Mutations vary from distortion of a single DNA building block to a large segment of a chromosome.

When mutation occurs in a cell, for the mutation to affect the traits expressed by the particular cell, it must follow this sequence directly:

A change in the sequence of DNA bases--> Joining amino acids in the sequence --> Appearance of characteristics.

If the mass of a material is 109 grams and the volume of the material is 24 cm3, what would the density of the material be? g/cm
MakcuM [25]
The units tell you:
g/cm³ = Mass (in grams) per (divided by) Volume (in cm³);
So:
109/24 = 4.54166..... ⇒ 4.54 g/cm³.
Always look at the units.
Just like for speed, you might have m/s so this is:
Distance (in meters) per (divided by) Time (in seconds).
