I believe Cortex is the last structure of the brain to complete its growth process. Surrounding the brain is the Cerebral cortex which resembles a half shelled walnut, it is the largest, most complex brain structure which accounts for 85% of the brain's weight, containing the greatest number of neurons and synapses, and responsible for the unique intelligence. It is the last brain structure to stop growing, it is sensitive to environmental influences for a much longer period than any other part of the brain.
<em>Carbon dioxide + light energy + water = carbohydrate (glucose) and oxygen</em>
Reactants: carbon dioxide, light energy, water
Products: glucose, oxygen
Answer:
Neutrophils
Explanation:
In this case of a ruptured appendix and peritontis, the neutrophils are more likely to be elevated above normal value because:
1. They are the most abundant white blood cells (WBCs), about 60%-70% of the total white blood cell count.
2. they help to defend the body against fungal and bacterial infections and heal tissues that are damaged. The most likely infection to occur from a ruptured appendix is a bacterial infection.
Other WBCs like eosinophil is involved in parasitic infection; basophil is involved in allergic reaction; while monocyte is involved in phagocytosis.
Answer: c) and b) are correct.
The brain is encased in a protective bony or cartilaginous housing in craniates.
The anterior end of the nerve cord is elaborated to form a brain in craniates.
Explanation: The craniates include the chordata with well-defined heads. This includes mammals, reptiles and fishes. So we can discard the other answers. Because most craniates have functional jaws, and the adults do not lose their chordate characteristics. The last one does not apply as a specific feature because the tunicate have neural crest but are not recognized as craniata.
