This is a random error/change in the DNA sequence. These may be inherited or occur in cells during the lifetime of the organism.
dusya [7]

This is the definition of a DNA mutation.

Depending on which part of the genome is affected, the consequences of a mutation may vary. A mutation is said to be hereditary if the mutated genetic sequence is transmitted to the next generation (see germinal mutations). It is one of the elements of biodiversity and one of the many factors that may be involved in the evolution of the species.

Find the total mass of three diamonds that have masses of 14.2 grams, 8.73 grams, and 0.912 gram
GaryK [48]
The total mass means that you need to add up all three diamonds' mass. So the calculation equation is 14.2+8.73+0.912 = 23.842 g.

4. If 0.130 g of p-aminophenol is allowed to react with excess acetic anhydride, what is the theoretical yield of acetaminophen
Dominik [7]

Hey There!

p-aminophenol (109.13 g/mol) + Ac2O (102.09 g/mol) ---> acetominophen (151.16 g/mol)

next, since you already know your limiting reactant (p-aminophenol), convert it to mols  :

0.130 g / (109.13 g/mol) = 0.00119 moles

now that's your theoretical max, since its a 1:1 mol ratio, so multiply by the new molecular weight. :

0.00119  * 151.16  = 0.180 g

Hope that helps!
