Identify the factors causing dehydration.

hunger and dehydration from tasting to digestion digestion of food digestion evs

  1. Hot and humid weather

  2. Habitation at high altitude

  3. Chronic illness

  4. All of the above

Show answer
Correct Option: D
Explanation:

Dehydration refers to a deficit of total body water, with an accompanying disruption of metabolic processes. It results from the loss of water and important electrolytes from the body, including potassium, sodium, chloride and many other minerals. The major factors which cause dehydration are Hot and Humid weather, habitation at high altitude and chronic illness. To prevent dehydration, one has to drink plenty of fluids and eat foods high in water such as fruits and vegetables. There are other preventive measures as well which include avoiding alcohol and caffeinated beverages, they increase dehydration. Wear light colored, absorbent, loose fitting clothing. Stay in cool, shades areas when possible, protect your skin with sun block. It can be treated with the help of using an oral rehydration solution which is easily available in chemists shops. Thus, the correct answer is option D.

Glucose solution gives immediate strength even

hunger and dehydration from tasting to digestion digestion of food digestion evs

  1. By quick digestion.

  2. Without digestion.

  3. By slow digestion.

  4. None of the above.

Show answer
Correct Option: B
Explanation:
Patients are given glucose by drip instead of food because the drip directly deposits the glucose into the bloodstream and hence the body parts get the glucose in a matter of minutes, but if it is given through food the glucose's energy would reach the body parts only after the digestion process and this will take a longer time. Hence to provide the patient with instant energy drip is chosen over food

So, the correct answer is 'Without digestion'.

If the condition of the patient is very bad due to dehydration the patient is put on a

  1. Blood drip.

  2. Glucose drip.

  3. Water drip.

  4. None of the above.

Show answer
Correct Option: B
Explanation:
Patients are given glucose by drip (during dehydration) instead of food because the drip directly deposits the glucose into the bloodstream and hence the body parts get the glucose in a matter of minutes, but if its given through food the glucose's energy would reach the body parts only after the digestion process and this will take a longer time. Hence to provide the patient with instant energy drip is chosen over food.

So, the correct answer is 'Glucose drip'.

Glucose drip is given for instant

Hence to provide the patient with instant energy drip is chosen over food.

So, the correct answer is 'Both B and C'.

Amount of water present inside human body cells is about

hunger and dehydration from tasting to digestion digestion of food digestion evs

  1. 15 litres

  2. 5 litres

  3. 25 litres

  4. 10 litres

Show answer
Correct Option: C
Explanation:
  • About 60% of human body weight is due to water and is mainly present within the cells of the body.
  • Intracellular fluid (within the cell) constitutes about 2/3 of body water.
  • Eg- In a person weighing 72 kg, 40 litres of fluid is present in the body out of which about 25 litres of water is present in the intracellular region (within the cells).
  • So, the correct answer is '25 litres'.

A person is given a ............. when he has loose motion and vomiting.

hunger and dehydration from tasting to digestion digestion of food digestion evs

  1. Salt solution

  2. Glucose solution

  3. ORS

  4. All of the above

Show answer
Correct Option: D
Explanation:
Vomiting and lose motion causes dehydration. Hence, the intake of fluids to maintain the electrolytes is balanced. Oral rehydration therapy (ORT) is a type of fluid replacement used to prevent and treat dehydration, especially due to diarrhoea. It involves drinking water with modest amounts of sugar and salts, specifically sodium and potassium.

So, the correct answer is 'All of the above'.

In extremely serious situations, fluids should be given

hunger and dehydration from tasting to digestion digestion of food digestion evs

  1. Orally

  2. Intradermally

  3. Intravenously

  4. None of the above

Show answer
Correct Option: C
Explanation:

Children and adults who are severely dehydrated should be treated by emergency personnel arriving in an ambulance or in a hospital emergency room, where they can receive salts and fluids through a vein (intravenously) rather than by mouth. Intravenous hydration provides the body with water and essential nutrients much more quickly than oral solutions, do something that's essential in life-threatening situations. 

Along with all other nutrients, the body also needs an adequate supply of water.

evs deficiency diseases need for nutrients nutrients needed by the body balanced diet and malnutrition food for health nutrition and its deficiency nutrition and its need

  1. True

  2. False

Show answer
Correct Option: A
Explanation:

The human body can last weeks without food, but only days without water. The body is made up of 50 to 75 per cent water. Water forms the basis of blood, digestive juices, urine and perspiration, and is contained in lean muscle, fat and bones. It helps to maintain the temperature of the body.

So, the correct option is 'True'.

Leaves appear green because they reflect green color from light spectrum. The part in the leaf that is responsible for the reflection is

evs deficiency diseases need for nutrients nutrients needed by the body balanced diet and malnutrition food for health nutrition and its deficiency nutrition and its need

  1. Inner membrane of Chloroplast

  2. Thylakoid space

  3. Thylakoid membrane

  4. Stroma

Show answer
Correct Option: C
Explanation:

Chloroplasts are green because they contain the green pigment chlorophyll in their thylakoid membranes. Chlorophyll is a pigment that absorbs red and blue light. So plants are green because chlorophyll reflects green light. 

So, the correct option is 'thylakoid membrane'.

Which of the following statements is false regarding the experiment carried out for photosynthesis?

evs deficiency diseases need for nutrients nutrients needed by the body balanced diet and malnutrition food for health nutrition and its deficiency nutrition and its need

  1. The two leaves experiment proved that photosynthesis took place only in the green part of the leaf which is exposed to sunlight

  2. Half leaf experiment indicate that co2 is required for photosynthesis

  3. In half experiment some part of leaf is inserted in a test tube having soaked cotton

  4. Starch is formed in a leaf

Show answer
Correct Option: A
Explanation:
Variegated leaves have green parts (where the cells contain chlorophyll) and white parts (where there is no chlorophyll). Only the parts that were green become blue/black with iodine solution, showing the importance of chlorophyll in photosynthesis. The parts without chlorophyll do not photosynthesize, and so they do not make starch and the iodine does not change colour.
So the correct option is 'The two leaves experiment proved that photosynthesis took place only in the green part of the leaf which is exposed to sunlight'.
