    sodium and other nutrients are reabsorbed into the bloodstream in the capillaries surrounding the tubules. Water moves via the process of osmosis: movement of water from an area of higher concentration to one of lower concentration. Tubular secretion is the final step in the process of urine formation which transfers materials from peritubular capillaries to renal tubular lumen and occurs mainly by active transport. ADH is secreted by the posterior pituitary (neurohypophysis) when there is a decrease

    Objective : To extract the DNA from onion samples. Introduction : Nuclues has DNA molecule in it. It is packaged into thread like structure known as chromosomes. Each and every chromosome is made up of DNA tightly coiled many times around proteins which is known as histones. Histones supports the structure. Chromosome cannot be visible even under the microscope if the cells are not dividing. DNA consist of 2 long polynucleotide which is composed of 4 types of nucleotide units. Nucleotides
