Answer: <span>B) Plant trees along canals and roadways on their property to filter runoff and prevent soil erosion
--------
The roots of trees help prevent the soil from being easily eroded by holding the soil in place and taking up the water. The other choices, A, C, and D would cause further erosion by removing objects that would stop the rain or by aiding erosion due to gravity.

Answer:
A = Activator
B = Effector
Explanation:
An activator is a protein which typically binds to a short (50–1500 bp) region of DNA which might be located either upstream (mainly) or downstream of a gene so as to cause increased transcription. This particular region of DNA is known as enhancer and activator is also known as transcription factor. Activator is a trans-acting factor which binds to the cis-acting factor which is enhancer so as to enhance transcriptional expression.
But another protein named as effector may restrict activator from binding to the enhancer leading to a decrease in transcriptional expression by binding to the activator allosterically. Allosteric binding of effector to the activator causes conformational change in activator so it can no longer bind the enhancer.
I guess because of concentration.....it stops !
