Clarification:
Bacterial meningitis is a severe infection leading to the Inflammation of the membranes surrounding the brain and spinal cord.
This infection is typically viral but can also be caused by fungi and bacteria. A vaccine is necessary to combat bacterial meningitis. Common signs include fever, neck stiffness, and headaches. It spreads through bacteria found in the throat of an infected individual and can be transmitted via coughing, sneezing, or kissing. The bacteria serve as pathogens that emit a toxin , which damages cells and components of the nervous system.
This condition is treated with intravenous antibiotics and corticosteroids in some cases.
Therefore, the correct sequential responses for the blanks are vaccine, bacteria, pathogens, cells, toxins, and antibiotics.
The key takeaway is that various substances have distinct biomass proportions. Variations in biomass percentages exist due to the differing elemental compositions of these substances. Each biomass is constituted by elements like carbon, hydrogen, nitrogen, and oxygen. For instance, the human body comprises 30% biomass, while the remainder consists of water. The breakdown of various elemental percentages includes carbon (12%), nitrogen (0.6%), hydrogen (62.9%), oxygen (24%), calcium (0.24%), and phosphorus (0.14%). At every level, only 10% of biomass is transferred to the next level, with the remaining 90% being dissipated as heat.
To enhance absorption effectiveness in the small intestine, the surface area of the mucosal lining is increased by structures like plicae circulares and intestinal villi .
Option A is correct. International trade expands markets, which is advantageous.
