    Here, tanA =a/a+1. And. TanB = 1/2a+1 A = tan–¹(a/a+1) B = tan –¹(1/2a+1) A+B = tan–¹(a/a+1) + tan–¹ (1/2a+1) = tan–¹[(a/a+1) + (1/2a+1) / 1 - (a/a+1)(1/2a+1)] = tan–¹(2a²+2a+1/2a²+2a+1) = tan –¹(1) = tan–¹[tan(π/4)] =π/4

    (i) Intracellular digestion, occurs inside the living cells with the help of lysosomal enzymes. Food particle is taken in through endocytosis. It forms a phagosome, which fuses with a lysosome. The digested material pass into the cytoplasm. The undigested matter is thrown out by exocytosis. It occurs in Amoeba, Paramecium, etc.
    (ii) Extracellular digestion In case of coelenterates digestion occurs in gastrovascular cavity. This cavity has gland cells which secrete digestive enzymes over the food. The partially digested fragmented food particles are ingested by nutritive cells. It occurs in Hydra, Aurelia, etc.

    NITROGEN FAMILY -- This group is also known as the nitrogen family. It consists of the elements nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), bismuth (Bi).The top two elements, nitrogen and phosphorus, are very definitely nonmetals, forming -3 charge anions. Nitrogen is a diatomic gas and phosphorus is a solid. The elements arsenic, antimony, and bismuth all have some characteristics of semimetals such as brittleness as a free element. CARBON FAMILY-- Group 14 is the carbon family. The five members are carbon, silicon, germanium, tin, and lead. All of these elements have four electrons in their outermost energy level. Of the Group 14 elements, only carbon and silicon form bonds as nonmetals (sharing electrons covalently).Metallic properties increase down the group. Carbon is a non-metal, silicon and germanium are metalloids, and tin and lead are poor metals (they conduct heat and electricity less effectively than other metals such as copper). Despite their adherence to periodic trends, the properties of the carbon family vary greatly. I Hope this will help you.?

    The first carbon in acetic acid, or CH3COOH , has an oxidation number of -3 . ... By comparison, the carbon on the right will lose all the electrons it contributes to the bonds with oxygen because oxygen is more electronegative than carbon. As a result, the right carbon will have an ON of +3.

    1. The new plants produced by artificial vegetative propagation will be exactly like the parent plants. Any desirable feature of the parent plant will be replicated in the new plants. 2. The fruit trees grown form seed may take many years before they start to bear fruit. But the fruit trees grown form cuttings or by grafting start to bear fruits much earlier. 3. The plants grown by vegetative propagation usually need less attention in their early year than the plants grown from seeds. 4. Many plants can be grown from just one parent plants by artificial propagation. 5 we can also get seedless plant by artificial propagation.
