Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

  • Physiological calories obtained from different food substances are - Carbohydrates give 4.0Kcal/g, Proteins give 4.0Kcal/g while fats give 9.0Kcal/g.
  • So, energy from 5g sugar = 5 x 4Kcal = 20Kcal
  • Energy from 4g albumin = 4 x 4Kcal = 16Kcal
  • energy from 10g+2g fat = 12 x 9Kcal = 108Kcal
  • lignin cannot be digested by humans because of the absence of digestive enzyme for lignin so no calories will be obtained from them. Ruminants are capable of digesting lignin.
  • Adding all the above-obtained values we get 144Kcal.

So, the correct answer is '144'.

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Answer is C. Three

A In rheumatoid arthritis an antibody against the Fc portion of IgG and different RFs can recognize different parts of the IgG-Fc. RF and IgG join to form immune complexes that contribute to the disease process.
B. The synovial membrane produces synovial fluid – a clear fluid that lubricates and nourishes the joint. Rheumatoid arthritis can affect any joint in the body but usually affects the small joints in the hands and feet before any of the larger joints such as hips, knees, shoulders and elbows are affected.
E.pannus — an abnormal tissue growth in the joints. This tissue can spread to your bones and cartilage, causing cartilage destruction, bone deterioration, pain, and inflammation.

  • 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'.

Multiple choice biology structure and functions of living organisms -ii dental care, eye care and hair care dental care and dental diseases salivary glands

With reference to a normal human being, which one of the following statements is not correct?

  1. Human saliva is slightly alkaline
  2. An adult human may secrete $1-1.5$L of saliva per day

  3. Saliva is secreted by six pairs of salivary glands in human beings

  4. The salivary enzyme(ptyalin) breaks down cooked starch into maltose
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Humans have three pairs of major salivary glands, not six pairs. The other statements are correct: human saliva is slightly acidic to neutral (though often cited around pH 6.8, effectively close to neutral or slightly alkaline depending on flow rate, but the gland count of six pairs total, meaning three on each side, makes option C false as it states six pairs meaning twelve pairs total).
