A hydrangea plant has blue flowers when grown in acidic soil, but has pink flowers when grown in basic soil. A clone of the pink-flowered plant is grown in acidic soil and produces blue flowers. This change in flower color is most likely due to

• sexual reproduction in the plants, resulting in variation

• asexual reproduction in the plants, resulting in variation

• genes being expressed in different ways due to environmental conditions

• a gene mutation that occurred after the clone was produced

A significant difference between the effects of the genetic information passed on from asexually reproducing parents to their offspring and sexually reproducing parents to their offspring is the

• degree of modification of the size of the chromosomes

• types of DNA subunits

• number of chromosomes in the body cells of the offspring

• amount of variation between the parents and the offspring

A normal sequence of DNA bases in a single human skin cell is CATGGC. If this sequence replicates in this cell and becomes GATGGC, this alteration will most likely be passed to

• every cell that develops from it

• all human body cells

• offspring of that human

• all skin cells of this person

Beta cells in the pancreas and human skin cells both contain the insulin gene. The beta cells can make insulin; however, skin cells cannot. Which process is responsible for this gene being expressed in one cell type and not in another cell type?

• mitosis

• replication

• differentiation

• meiosis

Information in segments of human DNA can be expressed by a bacterial cell as a result of

• sexual reproduction

• random mutation

• genetic variability

• genetic engineering

The appearance of this penguin chick with all black feathers might

• increase the types of foods penguins can eat

• decrease the diversity of the penguin population

• decrease the number of variations present in the black penguin population

• result in an increase in black penguins over time if the trait provides a reproductive advantage
