Answer:
(i) The exchange of chromatid parts between the maternal and the paternal chromatids of a pair of homologous chromosomes during meiosis is known as crossing over.
(ii) The removal of nitrogenous wastes from the body is known as excretion.
(iii) The repeating components of each DNA strand lengthwise is known as nucleotide.
(iv)An alteration in the genetic material that can be inherited is known as mutation
(v) The complex consisting of DNA strand and a core of histones is known as nucleosome
(vi) The filtrate left after reabsorption and tubular secretion is known as urine
(vii) The part of kidney tubules where the term urine is first used for the fluid in it is known as Collecting duct
(viii)The hormone secreted by alpha cells of the islets of Langerhans is known as glucagon.
(ix)The outer region of kidney containing the Bowman’s capsule is known as glomerulus.
