The correct Answer is:
To solve the question, we need to analyze the assertion and the reason provided. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that "Lymph is the filtered blood from capillaries, which is rich in oxygen, but devoid of RBC." - This statement is true. Lymph is indeed derived from the interstitial fluid that is filtered from blood capillaries. It contains nutrients, oxygen, and other substances, but it does not contain red blood cells (RBCs) because they are too large to pass through the capillary walls. 2. **Understanding the Reason**: - The reason states that "RBC can filter out due to small diameters of fenestra of capillary, but O₂ cannot do so." - This statement is false. The reason RBCs do not enter the lymphatic system is not because they can filter out, but rather because they are too large to pass through the capillary walls. Oxygen, on the other hand, can pass through the capillaries easily because it is a small molecule and can diffuse through the capillary walls. 3. **Conclusion**: - Since the assertion is true and the reason is false, we conclude that the correct option is that the assertion is true but the reason is false. ### Final Answer: - The assertion is true, and the reason is false.

Assertion : At the tissue level, 70 percent of CO_(2) formed from contabolism is trapped as bicarbonate in the RBCs. Reason : At tissue level, carbonic anhydrase in RBCs facilites the formation of CO_(2) and H_(2)O from bicarbonate.

Assertion (A) Both rhombic and monoclinic sulphur exist as S_(8) but oxygen exists as O_(2) . Reason (R ) Oxygen forms ppi-ppi multiple bond due to small size and small bond length but ppi-ppi bonding is not possoble is not possible in sulphur.

Assertion : The water rises higher in a capillary tube of small diameter than in the capillary tube of large diameter. Reason : Height through which liquid rise in capillary tube inversely proportional to the diameter of capillary tube.

Assertion : Portal system consists of veins which start from capillaries and end into capillaries. Reason : The hepatic portal vein carries blood from intestine to liver before it is delivered to the systemic circulation.

Assertion: Number of ways in which fruits can be selected from 4 apples, 3 oranges and 2 mangoes is 24. Reason: Zero or more things can be selected out of n identical things in (n+1) ways and number of ways when no apple, no orange and no mango is selected is 1^3 i.e. 1. (A) Both A and R are true and R is the correct explanation of A (B) Both A and R are true R is not the correct explanation of A (C) A is true but R is false. (D) A is false but R is true.

A metal foil is at a certain distance from an isotropic point source that emits energy at the rate P. Let us assume the classical physics to be applicable. The incident light energy will be absorbed continuously and smoothly. The electrons present in the foil soak up the energy incident on them. For simplicity , we can assume that the energy incident on a circular path of the foil with radius 5xx10^(-11) m (about that of a typical atom ) is absorbed by a single electron. The electron absorbs sufficient energy to break through the binding forces and comes out from the foil. By knowing the work function, we can calculate the time taken by an electron to come out i.e., we can find out the time taken by photoelectric emission to start. As you will see in the following questions, the time decay comes out to be large, which is not practically observed. The time lag is very small. Apparently, the electron does not have to soak up energy . It absorbs energy all at once in a single photon electron interaction. if work function of the metal of the foil is 2.2 eV, the time taken by electron to come out is nearly

Estimation of nitrogen: There are two methods for the estimation of nitrogen (i) Dumas method and (ii) Kjedahl's method. i. Dumas method: A known mass of compound is heated with copper oxide (CuO) in an atomsphere of CO_(2) , which gives free nitrogen along with CO_(2) and H_(2)O C_(x)H_(y)N_(z) + (2x + y//2) CuO rarr xCO_(2) + y//2 (H_(2)O) + z//2 (N_(2)) + (2x + y//2) CU The gaseous mixture is passed over a heated copper gauze which converts traces of nitrogen oxides formed to N_(2) . The gaeous mixture is collected over an aqueous solution of KOH which absorbs CO_(2) , and nitrogen is callected in the upper part of the graduated tube. ii. Kjeldahl's method: A known mass of organic compound (0.5 gm) is mixed with K_(2)SO_(4) (10 gm) and CuSO_(4) . (1.0 gm) or a drop of mercury (Hg) and conc. H_(2)SO_(4) (25ml), and heated in Kjeldahl's flask. CuSO_(4) or Hg acts as a catalyst, while K_(2)SO_(4) raises the boiling point of H_(2)SO_(4) . The nitrogen in the organic compound is quantitatively converted to ammonium sulphate. The resulting mixture is then distilled with excess of NaOH solution and the NH_(3) evolved is passed into a known but excess volume of standard HCl or H_(2)SO_(4) . The acid left unused is estimated by titration with some standard alkali. The amount of acid used against NH_(3) can be thus be known and from this the percentage of nitrogen is calculated. (a) C + H + S underset(H_(2)SO_(4))overset("conc.")rarr CO_(2) + H_(2)O + SO_(2) (b) N underset(H_(2)SO_(4))overset("conc.")rarr (NH_(4))_(2)SO_(4) (c) (NH_(4))_(2) SO_(4) + 2NaOH rarr Na_(2)SO_(4) + 2NH_(3) + 2H_(2)O (d) 2NH_(3) + H_(2)SO_(4) rarr (NH_(4))_(2) SO_(4) (iii) This method is not applicable to compounds containing N in intro and azo groups, and N present in the ring (e.g., pyridine) as N of these compounds does not change to (NH_(4))_(2)SO_(4) (ammonium sulphate) under these reaction conditions 0.50 gm of an organic compound was treated according to Kjeldahl's method. The ammonia evolved was absorbed in 50ml of 0,5M H_(2)SO_(4) . The residual acid required 60 ml of M/2 NaOH solution. Find the percentage of nitrogen in the compound
