Different rate of synapse production in different areas of the brain indicate that:
1. the different areas of the brain does not develop at the same time.
2. there is difference in timing of development of different skills and behavior categories and
3. different rate of synapses elimination occur in the brain.
The human brain start maturing before birth and continue to grow until about the age of twenty five. Even after this age, adult brain continues to mature as a result of the learning experiences that people are exposed to.
Carbon enters the atmosphere as carbon dioxide from respiration and combustion. Carbon dioxide is absorbed by producer to make carbohydrates and photosynthesis. consumers feed on the plants passing the carbon compounds along the food chain.<span />

→ Answer: RNA polymerase binds to the amylase gene promoter
→RNA elongation proceeds until RNA polymerase falls off the DNA
→A poly A tail is added to the 3' of pre-mRNA
→A mature mRNA is exported out of the nucleus
→ The tRNA charged with Met amino acid recognizes the AUG on the amylase mRNA bound to small ribosomal subunit
→Ribosome is fully assembled and translation elongation proceeds
→A release factor binds a stop codon on the amylase mRNA
→The growing polypeptide chain continues to insert itself inside the lumen of the ER
→Vesicles containing amylase leave the Golgi and fuse with plasma membrane to secrete protein from the cell
