Answer: b. The elderly have a higher risk from toxic pesticides because they are less able to eliminate environmental toxins.
Explanation:
The older adults are expected to have health problems after a pesticide exposure. This is because of the fact that their metabolism is slow and the liver and kidneys are not able to remove the pesticides from the body. The liver and kidney may get injured during the exposure of the high doses of pesticides.
The longer a pesticide stay in the body of an old person this may result in more severe injury. As the body is slow in metabolism that is the conversion of the chemicals in the pesticides into less toxic metabolites. Thus the elderly people will not be able to eliminate the toxin from the body. The toxin will damage the vital organs and can lead to death.
Answer:
The correct answer will be option D- blocking Cl channel.
Explanation:'
Quinidine is a stereoisomer of quinine derived from the bark of Cinchona plants which is used in the medication of the heart as class I antiarrhythmic agent. This alkaloid decreases the automaticity and increases the duration of the cellular action potential of the heart.
This alkaloid acts by blocking the neurotransmission through blocking of sodium and potassium channels responsible for the depolarization in non-nodal tissues like atrial cells, ventricular cells. This decrease in the neurotransmission of an action potential depends on the Ca⁺² ions and the quinidine can also act by blocking the Ca⁺² channels as well as B adrenergic receptor.
Thus, option D-blocking Cl channel is the correct answer.
Answer:
Increased eosinophils levels
Explanation:
Eosinophils are the first line of defense against parasitic infections and allergic reactions and will be elevated. Monocytes are a second line of defense and will be elevated in response to leukemias, lymphomas, and chronic inflammation. Basophils respond to allergic disorders and hypersensitivity reactions. Neutrophils are the first line of defense upon invasion of bacteria, fungus, cell debris, and other foreign substances.
Explanation:
Urine Formation -
Kidney contains nephrons , whose main function is excrete out unwanted substance from body , in the form of urine.
Urine formation involves three major process i.e. , Glomerular filtration , Tubular reabsorption and Tubular secretion.
Glomerular filtration -
It is the filtration process in which blood is filtered and the nitrogenous waste and water moves inside the glomerulus.
Tubular reabsorption -
In this process, the molecules and ions gets reabsorbed into the circulatory system.
Tubular secretion -
The secretion process in which , substances like hydrogen ions , creatinine and drugs are removed from the blood and collected in the duct.
And the end product of this is the Urine.
The dipstick test -
In this test , a thin plastic strip is treated with chemicals , and dipped into the sample of urine ,
Then the chemicals react with the urine and change the color .
It is used for the detection of Acidity , Protein , glucose , white blood cells .
