Which type of stimulus following a behavior removes something that is unpleasant? positive reinforcer negative punisher positive
Zolol [24]

The type of stimulus following a behavior removes something that is unpleasant is the negative reinforcer.

Stimulus is any signal. This can be in the form of touch, smell, taste, etc. This stimulus triggers the nerve cells of the body that send to signals to the brain to generate a response. For example, when one person touches a hot utensil, the touch of heat acts as a stimulus, where the brain sends response in the form of instantly removal of the hand.

Negative reinforcement is the response towards a stimuli that has not yet been received. For example, taking a medicine before any disease appears  is the acts of negative reinforcement.

DNA is composed of two strands, only one of which typically is used as a template for RNA synthesis. By what mechanism is the co
Andreyy89

To choose the strand the promoter acts to aim the RNA polymerase.

<h3>What does RNA polymerase do?</h3>

RNA polymerase synthesizes RNA by following a strand of DNA. The primary transcription enzyme is RNA polymerase. When RNA polymerase connects to a promoter sequence near the start of a gene, transcription starts (directly or through helper proteins). To create a fresh, complementary RNA molecule, RNA polymerase employs one of the DNA strands (the template strand) as a template.

Three distinct RNA polymerases (RNAPs), which transcribe various kinds of genes, are present in all eukaryotes. RNA polymerase I transcribe rRNA genes, RNA polymerase II transcribes mRNA, miRNA, snRNA, and snoRNA genes, and RNA polymerase III transcribes tRNA and 5S rRNA genes.
