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:
a. sexual reproduction in the plants
b. resulting in variationasexual reproduction in the plants
c. resulting in variationgenes being expressed in different ways due to environmental conditions
d. a gene mutation that occurred after the clone was produced

Option C, resulting in variation genes being expressed in different ways due to environmental conditions

Explanation:

Several genetic traits are affected by both internal and external environmental conditions. Some common examples are – height , color of eye, hair color, skin color, and even some genetic diseases.  

The internal environmental factors include – gender, temperature etc.

While the external environmental factors include drugs, chemicals, temperature, and light.  

Hence, the external environmental condition i.e pH of soil is producing different color of flowers in a given plant

Hence, option C is correct

i think the answer is a.keratin is the pigment responsible for skin color.

answer: the correct option is d. enzyme

lactase and carbonic anhydrase are the examples of enzymes.

lactase is an enzyme, which is present in the small intestine of mammals. it in the digestion of the disaccharide, lactose ( milk sugar) by converting it into two monosachharide, which are glucose and galactose.

carbonic anhydrase is present in the red blood cells. this enzyme plays significant role in the transport of co₂. it in the conversion of co₂ and h₂o into carbonic acid, which is then dissociated into bicarbonate ions and hydrogen ions.
