How are the mutations in a genome similar to printing a book? a. every letter in a book resembles the mutations in the genome. b. errors that appear in one copy can be copied to all other copies of the book. c. like printing errors, mutations always negatively affect the final product. d. just as a single book is printed at a time, a single mutation is read at a time.

B) Errors that appear in one copy can be copied to all other copies of the book.

Explanation:

Mutation means any change in the bases of DNA that are transferred to the offspring when organisms reproduces. No matter if the mutation is lethal or harmless, in both cases it will be transferred to the offspring upon reproduction. So from the options mentioned in the answers, answer B correctly illustrates the situation by comparing with the copying of a book.

If there is a mistake of one character, word or sentence in the newly printed book that goes unnoticed, it will be transferred to all the the copies and cause damage to the newly created books.

Note!  All mutations are not negative and few can help in the survival of the species when selection pressures change.

a

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
