How do environmental signals, like light influence the distribution of auxin in a plant? A. By increasing the concentration of auxin B. By destroying the auxin C. By causing auxin to migrate in to the shaded portion D. By decreasing the cells sensitivity the auxin

C. By causing auxin to migrate in to the shaded portion

Explanation:

Auxin is the most important plant hormone involved in the apical growth of plant parts. Auxin is evenly distributed in a plant with a normal light condition, however, when a particular part of a plant is exposed to sunlight, that illuminated part contains less auxin. The hormone is transported to the shady part of the plant via diffusion.

This causes more auxin to be present in the shady part than the illuminated part, hence, the shady part experiences a faster and elongated growth. This elongated growth in the shaded portion of the plant causes it to grow towards the direction of the light, a process called PHOTOTROPISM.

hi~~

i would say that hybridization occurs frequently in nature, because there are many types of hybrids that have occurred naturally, such as the mule (male donkey + female horse)
