उत्तर : 3. "an artery"
व्याख्या :
Answer: C) an artery Explanation: A pulse can be detected most easily in Arteries as they are under much greater pressure than veins because they are carrying blood away from the heart which is the pumping machine to force blood to move to all of the body. Every time the hear contracts, it can be felt in an artery where a surge of blood has just been forced. A capillary is too small to feel a pulse and a lacteal is part of the lymphatic system found in the small intestine.

उत्तर : 4. "All the above"
व्याख्या :
Answer: D) All the above Explanation: Processes that require or give off heat will be limited to changes of state, known as phase changes, and changes in chemical constitution, or chemical reactions. Changes of state involve a solid melting, a liquid freezing, a liquid boiling or a gas condensing. An exothermic process is one that gives off heat, which is transferred to the surroundings. An endothermic process is a reaction which heat has to be supplied to the system from the surroundings. Here in all the given options, heat is taken away from them to change there phase. Liquid to Solid --- Freezing Gas to Liquid --- Condensation Gas to Solid --- Deposition are all examples of exothermic processes.

उत्तर : 2. "FALSE"
व्याख्या :
Answer: B) FALSE Explanation: FALSE. Basophils number will not be increased when parasitic invasion occurs. Basophils are a type of white blood cell. Although they're produced in the bone marrow, they're found in many tissues throughout your body. They're part of your immune system and play a role in its proper function. Basophils appear in many specific kinds of inflammatory reactions, particularly those that cause allergic symptoms. If your basophil level is low, it may be due to a severe allergic reaction. Basophils contain anticoagulant heparin, which prevents blood from clotting too quickly. They also contain the vasodilator histamine, which promotes blood flow to tissues.

उत्तर : 1. "they are eukaryotic cells"
व्याख्या :
Answer: A) they are eukaryotic cells Explanation: If you were to produce a protein in bacterial cloning systems, you would not get the same post transcriptional and post translational modifications because the prokaryotic and eukaryotic systems work differently on the modifications. Thus human recombinant protein genes are usually cloned in yeast cells. Also since they have a short generation time, they can be easily culture.
