Answer:
The count of cells observed will rely on the dimensions of both the cells and the size of the red circle on the slide.
Explanation:
Cells come in varying sizes and this variation affects how many cells can be seen through a microscope. The way the smear is prepared also plays a role, as does the amount and type of dye used on the slide.
In conclusion, the number of cells visible is somewhat subjective and can only be definitively calculated through experience.
Response:
It would need a lower amount of bicarbonate to neutralize the acid.
Explanation:
Sodium bicarbonate (NaHCO3) is a partially soluble sodium salt that breaks down in water to create a weakly basic buffer solution. It separates in water releasing bicarbonate ions (HCO−), sodium ions (Na+), and H+.
2 NaHCO3(s) → Na2CO3(s) + CO2(g) + H2O(g)
Buffer solutions are maintained in equilibrium. In a solution with a strong acid, the conjugate base reacts, while other carbonate ions release to form carbonic acid, driving the solution back toward balance.
HA ⇄ H+ + A-
Due to its buffering capability, which is how effectively it stabilizes the equilibrium, less bicarbonate will be required later on to neutralize the acid.
Response:
vaccine
bacteria
pathogens
cells
toxins
antibiotics
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 proper answer is option-E.
The activity of the autonomic nervous system (ANS) is primarily regulated by the hypothalamus. This organ's autonomic centers govern the secretion of hormones from the adrenal medulla, such as adrenaline and norepinephrine.
Moreover, the hypothalamus also influences the vasomotor center, which is essential for regulating blood pressure.
Thus, the correct option is hypothalamus.
