Answer:carbon,hydrogen, nitrogen, oxygen, phosphorus, sulphur
Explanation:living things are characteristized by hierarchy in their organisation.macromolecules are made up of elements each with it's unique chemical bonds.
Within the cell, macromolecules are found in organelles ,which form the cells.the cells combines into tissues,which combines into organs .organs systems consists of similar functional organs.
living things commonly contains carbon, hydrogen, nitrogen,oxygen, phosphorus and sulphur.

Water molecules tend to stick to each other; once a few molecules are drawn up through the filter paper, more molecules will follow.

Answer:
Over the ages the tendency of crop improvement efforts has been to select varieties with traits that give the highest return, largely by concentrating on genetic strains that combine the most desirable traits. The resulting homogeneity and uniformity can offer substantial advantages in both the quantity and quality of crop harvested, but this same genetic homogeneity can also reflect greater susceptibility or pathogens. Thus it appears the more that agricultural selection disturbs the natural balance in favor of variety uniformity over large areas, the more vulnerable such varieties are to losses from epidemics. The increased risks presented by genetic selection and the increased cultivation of only a few selected cultivars are easily perceived. Chapters 1 and 2 of this reports focus on crop vulnerability, because it is a broadly recognized problem. The issue of genetic vulnerability, however, is only one of several important problems affecting the management of global genetic resources.
