•  To diagnose anaemia, your doctor may ask you about your medical and family history, perform a physical exam, and run the following tests: Complete blood count (CBC) or Red cell distribution width (RDW).
•   A CBC is used to count the number of blood cells in a sample of your blood.
• Red cell distribution width (RDW) is also the test to diagnose anaemia. For instance, you'll probably have greater differences in red blood cell size if you have anaemia in these test.
• Hence, Anaemia can be diagnosed by the shape and size of RBC only.
• So, the correct answer is 'Shape and size of RBC only'.

• Vegetables are parts of plants that are consumed by humans or other animals as food. For example, spinach.
• Leafy greens, such as spinach, kale, swiss chard, collard, and beet greens contain between 2.5–6.4 mg of iron per cooked cup.
• For example, 100 grams of spinach contains 1.1 times more iron than the same amount of red meat and 2.2 times more than 100 grams of salmon (26, 27).
  
• Hence Vegetables are a good source of iron is a true statement.

Fehling's reagent is a chemical reagent used to differentiate between water-soluble carbohydrates and ketone functional groups. This reagent is used for testing the presence of reducing sugars. Reducing sugars give a positive result to this test due to the presence of oxidisable aldehyde group.

Hepatitis is sometimes caused due to excessive consumption of alcohol. This results to liver cirrhosis. This is called a non-viral hepatitis.

Anaemia is a condition in which is there is shortage of blood or shortage of red blood cells. It results due to loss of blood during accident or pregnancy. It can also results due to insufficient iron in the body to produce enough of haemoglobin.

Houseflies live for up to 3 weeks and are active during the warmer part of the year. An adult female deposits 50 to 100 eggs at a time and about 500 eggs over her lifetime. The eggs are deposited in rotting organic matter. They hatch after about 12 hours and the larvae, or maggots, feed on the rotting organic material. A maggot passes through three larval stages and then forms a pupa, or cocoon. The adult fly emerges from the cocoon. Houseflies typically develop from egg to adult within 10 days. 

The diseases, which spread from one person to another person or from animal to person are called as communicable diseases. It is also termed as infectious or contagious diseases. Housefly is a major factor in contributing communicable diseases. Housefly comes in contact with waste products and eatables. When it flies from wastes to eatables, it transports bacterial agents from wastes to eatables. Due to consumption of such eatables, the persons infected with microbes of various diseases, person gets sick. 

House flies are the vectors of several infectious agents. The pathogen may attach with flies when they sit on the waste materials. They cause typhoid, cholera, salmonellosis, dysentery, tuberculosis, anthrax, and parasitic worms carried to human food on the fly’s body parts or in its regurgitations or defecations.

Sanitation is the primary method for controlling houseflies because it removes their breeding grounds, such as decaying organic matter and waste.

The housefly undergoes complete metamorphosis, which consists of four stages: egg, larva (maggot), pupa, and adult.
