Answer:
When neurons communicate, an electric impulse triggers the realease of neurotransmitters from the axon into the synapse. The neurotransmitters cross the synapse and bind to special molecules on the other side ,called receptors. Receptors are located on the dendrites. Receptors receive And process the messages
Answer:
Tidal energy is renewable energy powered by the natural rise and fall of ocean tides and currents
Explanation:
Experimentation makes it possible for researchers to isolate cause and effect by allowing the researchers to manipulate one factor while controlling the other factors. This is achieved by creating two groups, subjects are put in these groups randomly in order to reduce experimental biases.
The two groups are the experimental group and the control group. The subjects in the experimental group will be exposed to treatment while the subjects in the control group will not be exposed to the treatment.
Answer:
The correct answer will be option- three RNA polymerase
Explanation:
The RNA polymerase is the enzyme which helps the process of formation of RNA from DNA during transcription.
Prokaryotes possess only one type of RNA polymerase which form all type of RNA whereas the eukaryotes possess three types of RNA called RNA polymerase I RNA, polymerase II and RNA polymerase III.
These RNA polymerases catalyse the synthesis of different RNA in eukaryotes as RNA polymerase I help in the synthesis of rRNA, RNA polymerase II in miRNA, mRNA, snoRNA and RNA polymerase III in 5S rRNA and tRNA.
Thus, three RNA polymerase is the correct answer.
It would be secondary. This is because a natural disaster would cause an immediate effect on plant life in the area.
