1. skin cancer should be noninfectious.
2 .diabetes should be infectious.
3. cold should be noninfectious.
4. flu should be infectious.
5. aids should be infectious

Answer/Explanation:

skin cancer: infectious

diabetes: noninfectious

cold: infectious

flu: infectious

AIDS: infectious

The errors in the table are: Skin cancer is infectious (which is wrong), Flu is noninfectious (which is wrong), and AID is noninfectious (which is also a wrong statement). There are three (3) wrong statements in this table.

Explanation:

Skin cancer is caused by the loss of divisional control mechanism possessed by healthy cells, which makes the cell to defer apoptosis or programmed cell death, and tend to multiply at a faster uncontrollable rate and eventually lead to tumors. This is due to an alteration to the genetic makeup at the segment that controls cell division in the DNA. This problem cannot be passed to others since it is not by an external infectious agent such as bacteria or viruses.

FLU is caused by the contagious viral agent called the Influenza virus; it can be transmitted from an infected individual to a healthy person; it is infectious. Likewise, AIDS, which is Acquired Immune Deficiency Syndrome, is caused by the highly infectious virus called Human Immunodeficiency Virus.

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.
