On way to test a mineral is to break it and see how many directions of Cleavage it has

Answer: CLEAVAGE

Explanation: Cleavage is a property of the rock that shows how a rock breaks along a certain curved surface. Along this surface the bonding between the mineral is weak. Some of the rocks that exhibits this cleavage property are slate, limestone, shale as well as schist.

This property helps in determining the planes of weaker zones along which cleavage and fracture could possibly occur. There are two types of rock cleavage and they are as follows-

  • Slaty cleavage
  • Flow cleavage.

Which of these would be considered a transgenic organism? a human treated with insulin produced by E. coli bacteria a rat with r
MA_775_DIABLO [31]

Answer:

a rat with rabbit hemoglobin genes

Explanation:

When the genome of an organism is modified in the field of genetic engineering,by transplanting the gene(DNA) from one organisms to another,(by vectors) or alteration of the gene components,the resulting organism produced or formed is called Transgenic organism.

This process of genetic engineering makes use of recombination of genes to alter the genome of the transgenic organism.

Thus by transferring to  rat ( the DNA for Hb) as the  rabbit Hb,the gene( or genome) for producing Hb in tats has been modified by that of rabbit.Hence Rat is said to transgenic.

Besides animals crop plants are also genetically modified.Thus the genome of some crops are altered to resist herbicides and pesticides. Some species of rice (golden rice)have been  modified to  add certain  vitamins to improve the nutritional values.

Genetically modified bananas as edible vaccines are another example
