Identify the vitamin which helps to cure anaemia.
-
Vitamin A
-
Vitamin B12
-
Vitamin K
-
Vitamin E
- Vitamin B-12 is a water-soluble vitamin, like all other B-vitamins. This means it can dissolve in water and travel through the bloodstream.
- The human body can store vitamin B-12 for up to four years. Any excess or unwanted vitamin B-12 is excreted in the urine.
- The human body produces millions of red blood cells every minute. These cells cannot multiply properly without vitamin B-12. The production of red blood cells reduces if vitamin B-12 levels are too low. Anaemia can occur if the red blood cell count drops. Hence, Vitamin B12 helps to cure anaemia.
Which of the following is a source of iron?
-
Green vegetables
-
Amla
-
Jaggery
-
All of the above
Iron is an important component of hemoglobin. It carries oxygen from lungs to different parts of the body. Sources of iron includes sunflower seeds, nuts, beef, beans, green leafy vegetables, tofu, amla, jaggery. Iron deficiency can leads to anemia.
Assertion : Blood sugar level falls rapidly after
hepatedomy.
Reason : The glycogen of the liver is the principal
source of blood sugar.
-
If both the assertion and the reason are true and the reason
is a correct explanation of the assertion -
If both the assertion and reason are true but the reason is
not a correct explanation of the assertion -
If the assertion is true but the reason is false
-
If both the assertion and reason are false
-
If the assertion is false but reason is true
In liver , glycogen a reserve food material is changed into glucose (glycogenolysis ) and released into blood. Under abnormal condition ,liver can convert proteins and fats into glucose by complex chemical reactions i.e., called gluconeogenesis. Thus, due to hepatectomy blood sugar level falls rapidly.
There is less iron in the blood of the person suffering from anaemia.
-
True
-
False
- Anaemia is a decrease in the total amount of red blood cells (RBCs) or haemoglobin in the blood or a lowered ability of the blood to carry oxygen.
- When anaemia comes on slowly, the symptoms may include feeling tired, weakness, shortness of breath or a poor ability to exercise. Hence, There is less iron in the blood of the person suffers from anaemia.
Pernicious anaemia is caused by
-
Low RBC count
-
Death of WBC
-
Obstruction of RBC maturation
-
Destruction of young RBC.
The reduced flow of oxygen in blood occurs in
-
Malaria
-
Anaemia
-
Cancer
-
Typhoid
- Anaemia is a decrease in the total amount of red blood cells (RBCs) or haemoglobin in the blood or a lowered ability of the blood to carry oxygen.
- When anaemia comes on slowly, the symptoms may include feeling tired, weakness, shortness of breath or a poor ability to exercise. Hence, The reduced flow of oxygen in the blood occurs in Anaemia
Green leafy vegetables are a rich source of ________.
-
Sodium
-
Iron
-
Magnesium
-
None of the above
Iron is an important component of hemoglobin which is a part of red blood cells. It carries oxygen from lungs to different parts of the body. Green leafy vegetables such as spinach are rich sources of iron. Other foods containing iron include sunflower seeds, nuts, beef, beans, tofu, amla, jaggery. Iron deficiency can leads to anemia.
Anaemia can be diagnosed by the
-
Shape and size of RBC only
-
Number of platelets only
-
Size and shape of WBC only
-
Number of WBC only
- 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 good source of iron.
-
True
-
False
- 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.
Choose the correct answer from the alternatives given.
Fehlings reagent is used for testing:
-
Reducing sugars
-
Non-reducing sugars
-
Stereoisomerism
-
Asymmetry of carbon atoms
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.
