Tay-sachs disease is a human genetic abnormality that results in cells accumulating and becoming clogged with very large, complex, undigested lipids. which cellular organelle is most likely defective in this condition?

The correct answer will be- lysosomes

Explanation:

Tay-Sachs is a genetic disorder which results in the dysfunction of the central nervous system of the body.

This disease is categorised as the lysosomal storage disease as the deficiency of hexosaminidase A enzyme leads to the accumulation of the fatty acids in the lysosomes which are considered the digestive organelle of the cell.

This abnormal lysosomes with accumulated gangliosides fatty acids destroys the surrounding organelles and the cell and thus cause the disease. Therefore, lysosome is the correct answer.

a mercury barometer is a device that uses the physical properties of mercury in a tube to measure barometric pressure. mercury barometers are used for : -

1. measurement of atmospheric pressure  

2. determining the altitude of a place

3. weather forecasting

4. calibration and checking of aneroid barometers

5. application in fluid mechanics

6. measurement of pressure in aircrafts

7. surface weather analysis

8. preparation of barographs

9. usage in physical sciences like physics, astronomy & chemistry

10. preparation of aircraft altimeters

characteristics of mercury barometer : -

1.used to define and measure atmospheric pressure.

2.on the average at sea level the column of mercury rises to a height of about 760 mm.

3.this quantity is equal to 1 atmosphere.

4.it is also known as standard atmospheric pressure.

5.a barometer in which the weight of a column of mercury in a glass tube with a sealed top is balanced against that of the atmosphere pressing on an exposed cistern of mercury at the base of the mercury column, the height of the column varying with atmospheric pressure.

metric time was an attempt to create a standard unit of time based off of 10, but it never took off an is not included in the metric system (si)
