Answer:
Two synapses.
Explanation:
Synapse or Synaptic cleft is the space two neurons or between a neuron or target organ where the signal is carried by neurotransmitter. Nerve signal first travel through interneuron to motorneuron passing through the first synapse, then the signal will travel to effector organ from motor neuron by passing through second synapse.

Answer:
abscisic acid
Explanation:
Abscisic acid is a plant hormone also known by the acronym ABA, whose function is growth inhibition and stomatal closure. We can also attribute to abscisic acid the function of delaying seed germination in the process known as vegetable dormancy. Usually the accumulation of this hormone happens at the beginning of the development of some seeds and is related to delayed germination.
Abscisic acid induces seed dormancy, but decreasing levels of this hormone release seeds from dormancy.
 
        
             
        
        
        
Attached are two images concerning DNA. 
The first image is a diagram that illustrates the base paring of DNA. First, there is the ribose-phosphate backbone that keeps the DNA together. Then the bases thymine and adenine are joined together by two hydrogen bonds. On the other hand, the bases guanine and cytosine are joined together by three hydrogen bonds. 
The second image shows the helical structure of the DNA.
