1. Seleccione un proceso de la vida cotidiana el cuál pueda representarse por medio de una reacción química. 2. Determine las cantidades de reactivos necesarias para que este proceso pueda generarse.
3. Realice cálculos estequiométricos donde por medio de factores de conversión cambie las cantidades de reactivos en unidades de moles, moléculas y átomos.

humans are now responsible for causing changes in the environment that hurt animals and plant species. we take up more space on earth for our homes and cities. we pollute habitats. human activity often changes or destroys the habitats that plants and animals need to survive.

what bodys are there orbiting?

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
