Resumen
El crecimiento de la población a nivel mundial y el aumento del uso del agua para diferentes actividades, ha
incrementado los niveles de contaminación. Esta contaminación está relacionada con los vertidos de origen doméstico e
industrial a los cuerpos de agua. En el caso de los residuos de origen doméstico, la carga contaminante está representada
por altos porcentajes de materia orgánica y microorganismos de origen fecal. Estos microorganismos son causantes de
enfermedades de origen hídrico, que generan altos porcentajes de morbi-mortalidad en la población. El control de la
calidad microbiológica del agua de consumo y de vertido, requiere una serie de análisis dirigidos a determinar la
presencia de microorganismos patógenos. El diagnóstico de estos microorganismos, requiere laboratorios especializados
y representa varios días de análisis y costos elevados. Como alternativa a estos inconvenientes, se ha propuesto el uso de
indicadores microbianos que se puedan identificar mediante el uso de métodos sencillos, rápidos y económicos. Este
trabajo hace una revisión de los principales indicadores de contaminación fecal y su significado en la evaluación de la
calidad del agua
Answer 1: Option C, heterozygous dominant
Explanation: For example the genotypes of these true breeding white and purple flowers is pp and PP, respectively, then the offsprings would be all Pp. This is a heterozygous genotype and it will express dominant trait only.
Answer 2: Option C, homozygous recessive
Explanation: If the trait is recessive, then it will express only when both the alleles of the genotype are recessive alleles. And this would be homozygous state. For example, 'pp' would be the genotype for white flowers.
Answer 3: Option D, white and red
Explanation: If we want that all offsprings should be heterozygous, then parents should be true breeding, which means homozygous. Here, roan is a heterozygous trait [WR]. So both parents should be homozygous, like RR and WW. Then only all offsprings would be heterozygous.
The correct answer is D. Flask 3 (only). This is because fish produce carbon dioxide products of cellular respiration and they do not undergo photosynthesis therefore not consuming carbon dioxide.
This is where cellular respiration is being involved.
Cellular respiration is termed as process and reaction of metabolic which takes place in organisms where biochemical energy are converted to adenosine triphosphate from nutrients where waste product is being released.
Catabolic reactions is involved in cellular respiration where large molecules are broken to small molecules so as to release energy.

Adaptations make different species unique and able to survive and thrive in their own habitat. For example, hibernation is a behavioral adaptation that grizzly bears have. ... Though they are in dens and slowing down, even female polar bears don't exhibit true hibernation but can go up to 8 months without eating.
The steps for DNA replication are generally the same for all prokaryotic and eukaryotic organisms. Unwinding the DNA is accomplished by an enzyme named DNA helicase. Manufacturing new DNA strands is orchestrated by enzymes called polymerases.
