Altering patterns of gene expression in prokaryotes would most likely serve an organism's survival by
a. allowing each gene to be expressed an equal number of times organizing gene expression, so that genes are expressed in a given order
b. allowing an organism to adjust to changes in environmental conditions
c. allowing environmental changes to alter a prokaryote's genome
d. allowing young organisms to respond differently than more mature organisms

Allowing the organism to adjust to changes in environmental conditions.

Explanation:

Gene may be defined as the functional segment of the DNA that codes for the particular protein and responsible for the genotype and phenotype expression of the organisms.

The gene expression of the particular genes can be modified according to the activity and the external environment of the organism. The altered expression of gene is important as it helps the prokaryotic organism to adapt better in their environment.

Thus, the correct answer is option (b).

answer; i believe the correct answer is (replication is not conservative);

answer : haversian

[explanation: -(compact bone is organized as parallel columns, known as haversian systems, which run lengthwise down the axis of long bones. these columns are composed of lamellae, concentric rings of bone, surrounding a central channel, or haversian canal, that contains the nerves, blood vessels, and lymphatic system of the bone)]
