Question Discussion & Solution

The correct answer is Transpiration.

• Transpiration is the loss of water from a plant in the form of water vapour.

 Additional Information

• The amount of water that plants transpire varies greatly geographically and over time.
• The transpiration depends upon
  • Temperature,
  • Relative humidity,
  • Wind and air movement,
  • Soil moisture availability and
  • Type of plant.

Guttation

• Guttation is the loss of water in the form of water droplets from hydathodes (small pores) on the leaf margin of some vascular plants.

Evaporation

• Evaporation is the process by which water changes from a liquid to a gas or vapour.

Translocation

• The movement of sucrose and other substances like amino acids around a plant is called translocation.

Functional cohesion:

A module is said to possess functional cohesion, if different functions of the module co-operate to complete a single task.

Example of Functional cohesion

A module containing all the functions required to manage employees’ pay-roll displays functional cohesion

The correct answer is Liver.

Key Points

• Excessive consumption of alcoholic drinks causes damage to the Liver.
  • Alcohol is readily absorbed from the digestive tract, and up to 98% is metabolised in the liver.
  • Each liver cell contains three pathways for alcohol metabolism.
  • All of these result in the production of a highly toxic metabolite which can contribute to liver cell damage.
  • With regular alcohol use, the regenerative ability of liver cells may be inhibited and lead to sustained liver damage.
  • Long term heavy alcohol use may lead to fat accumulation in the liver, which may progress to alcoholic hepatitis, or liver cirrhosis.
  • Over time, excessive alcohol use can lead to the development of chronic diseases and other serious problems including -
    • High blood pressure, heart disease, stroke, liver disease, and digestive problems. 

Additional Information

• Kidney:
  • Healthy kidneys remove wastes and extra fluid from your blood.
  • But when your kidneys fail, wastes and extra fluid can build up in your blood and make you feel sick. 
  • Kidneys can become damaged from a physical injury or a disease like diabetes, high blood pressure, or other disorders.
  • High blood pressure and diabetes are the two most common causes of kidney failure.
  • Kidney failure does not happen overnight.
• Lungs:
  • Chronic alcohol abuse and heavy drinking can greatly increase the risk of several pulmonary conditions.
    • including lung disease, alcoholic pneumonia, acute lung injury, and acute respiratory distress syndrome.
  • Smokers are more likely than nonsmokers to develop heart disease, stroke, and lung cancer.
    • Smoking can cause lung disease by damaging your airways and the small air sacs (alveoli) found in your lungs.
    • Lung diseases caused by smoking include COPD, which includes emphysema and chronic bronchitis.
• Heart:
  • Smokers are at greater risk for diseases that affect the heart and blood vessels.
  • Increases in your blood pressure can also be caused by weight gain from excessive drinking.
  • Heavy drinking weakens the heart muscle, which means the heart can't pump blood as efficiently.
    • It's is known as cardiomyopathy and can cause death, usually through heart failure.

The correct answer is CTRL + F2.

• Print Preview is a feature that displays on the screen what a hard copy would look like when printed.
  • Press Ctrl + F2 to open the print preview for the document.
  • By using the print preview, you can find any errors that may exist or fix the layout before printing, which can save ink or toner and paper by not having to print more than once.

Additional Information

• To open the print preview feature, click the print preview icon on the toolbar, like that shown in the picture, or click File and choose the Print Preview option.
• Some programs, like newer versions of Microsoft Office applications, show a print preview on the Print page.
• In these cases, there is no Print Preview option in the program's menu.
• Many programs do not have a shortcut key for the print preview feature.
• However, you can press Alt+F to open the file menu and press V, R, or the other underlined character (Mnemonic) for the Print Preview option.
• In programs like Microsoft Word, while in the print preview, you can change the page orientation from Portrait Orientation to Landscape.
• Orientation to view the page in landscape.
• Unfortunately, not all programs support this ability.
• If the program you're using has no settings or options in print preview, you cannot view how your page would print in landscape mode.
