We breath in oxygen and out carbon dioxide where plants breath in carbon dioxide and out oxygen. that is how we are alike when it comes to energy and like plants it takes time for us to grow.
hope this helps
A state in which opposing forces are balanced

velocity is a vector so it has a magnitude and direction so the answer would be B
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.
