Q1c(i) 1. the plant absorbed much nitrates 2. its roots contained denitrifying bacteria
(ii)1. add fertilizers 2. plant legume plants {e.g pea plant}
(d) their roots have roots nodules which contain nitrogen fixing bacteria , they absorb nitrogen from the air and convert into nitrates , which are than used by plant
Q5 (b) (ii) this process requires energy as active transport takes place , as most energy is utilized in thx process there is very less energy available for growth . hence , rate of growth decreases
Q3 (c)(i) 1. lack of excercise 2. excessive consumption of fatty diets
(ii) the artery after point B wll all be shaded
(d) 1. valves are present
they prevent back flow of blood
2. wider lumen
this helps in decresing the blood pressure in veins
Q4 (a)(ii) 1. by mutations
2. by incomplete antibiotic prescribed course
3. the resistant bacteria than reproduce soon produce many ressistant bacteria as they are nt killed
4. by natural selection
(b)(ii) 1. decomposing bacteria convert animal and plant protein into ammonia
2. nitrosomonas bacteria convert ammonia into nitites
3. nitrobacter bacteria convert nitrite into nitrate
4. nitogen fixing bacteria convert nitrogen into nitrates
Q3 (II) all small molecules enter renal ccapsule from glomerulus by ultra filtration . the fluid than passes through renal tubule , here reabsorption takes place . almost all glucose , some water and some salts are absorbed back , rest fluid is emtied into uretur
(iii) 1. active transport
2. osmosis
