Question
Which tree produces natural
rubber?Solution
The major commercial source of natural rubber latex is the Pará rubber tree ( Hevea brasiliensis) a member of the spurge family, Euphorbiaceae. This species is preferred because it grows well under cultivation. A properly managed tree responds to wounding by producing more latex for several years. Mesoamerican trees are domesticated plants of Mesoamerica , established by agricultural developments and practices over several thousand years of pre-Columbian history, include maize and capsicum. Melaleuca trees have white flowers which are small and crowded in bottlebrush-like spikes at branch tips. The fruit are short, cylindric or squarish, woody capsules with many tiny seeds. Melaleuca produces huge quantities of seeds, which become small trees, which grow into almost impenetrable monocultures. Pine trees reproduce by producing seeds. Unlike deciduous trees, which produce seeds that are surrounded by fruit, pine seeds are located on scales of structures called cones (pine cones).
If total number of factors of 3,240 is 'x', then find the value of (x - 3)(x + 5).
HCF of two numbers 65 and 104 can be expressed in the form of (40m – 107) whereas LCM of these two numbers can be expressed in the form of (60n – 20...
Three numbers are in the ratio 3:7:2 respectively. If the HCF of the numbers is 5, then find the LCM of the numbers.
