B. inherit the gene from their mother only. C. inherit the gene from their father only disease. D. have had a spontaneous mutation upon conception that caused the

Explanation / Answer

38. A macromolecule is a molecule containing a large number of molecules. Arginine, Proline and Guanine are all amino acids and relative to Hemoglobin are small molecules.

39. Different kinds of cells associated with immunity such as immature T cells, T and B Lymphocytes, Natural Killer cells, macrophages and monocytes are transferred to maternal tissues. Increased reports state that microchimerism can be associated with Auto Immune diseases. So, True.

40. Meiosis also called as reductional division, is important in maintaining the number of chrosomes of a species during proliferation, Thus meiosis is integral to Sexual reproduction.

41. Sun is the basic source of energy for every life, since it is the sun which provides energy to plants(primary producers) for photosynthesis, which in turn are source of energy for other organisms.

42. Enzymes lower activation energy, by binding with the substrate, thus configuring it in such a way that lesser energy is required for the said reaction.
