Answer:
head of the humerus, Acromial end of the clavicle
Explanation:
The shoulder is made up of three bones: the scapula, the clavicle and the humerus (upper arm bone). Two joints in the shoulder allow it to move: the acromioclavicular joint, where the highest point of the scapula (acromion) meets the clavicle at its acromial end (the sternal end of the clavicle is bounded to the sternon), and the glenohumeral joint. The scapula also bounds to the head of the humerus, it is, the distal superior end.
Answer:
When AraC binds to arabinose to initiate the process of transcription, then AraC is acting as an Activator.
Explanation:
Transcription is a process that help to produce messenger RNA from the DNA that is present in the nuceloids of bacteria cells. The production of these mRNA however, depends on the intracellular condition of the bacteria, for example, if there is a need for the protein coded for by the segment or not. In the case of this bacterium, the AraC can act as a repressor only when there is no arabinose sugar in the cell. In the scenario above, AraC will act as an activator because of the presence of the sugar arabinose.
This occurs because REM sleep may provide at least part of the stimulation necessary to correctly develope the immature brain of infants.
REM sleep provides the electrical activity necessary to establish neural connections that include the development of synapses in the brain. These neurological process enables development of sensory, motor, learning and memory system.
