Leer el siguiente texto de las teorías evolutivas y expresar cuales son las principales semejanzas y diferencias
IceJOKER [234]

Answer:

Lamarck creía que la evolución era una consecuencia de la presión ambiental mientras que Darwin expresó que el mecanismo de evolución es la selección natural

Explanation:

Lamarck desarrolló una teoría en la que propuso que los organismos evolucionaban como una consecuencia de la influencia ambiental y que los cambios fenotípicos causados por el ambiente podía ser trasmitidos a través de generaciones. Por otra parte, Darwin desarrollo una teoría en la cual las especies evolucionan a través de un proceso que él denominó selección natural (supervivencia del más apto) : aquellos organismos mejor adaptados a su ambiente tendrán más chances de sobrevivir y de reproducirse, pasando sus genes a la siguiente generación. En relación al cuadro comparativo, Lamarck creía que las jirafas se adaptaban a su ambiente para sobrevivir, mientras que Darwin propuso que aquellas jirafas que mejor se adaptaban a un ambiente cambiante tenían más chances de sobrevivir. Lamarck también creía en la idea del uso y desuso de órganos: las jirafas con el tiempo podía desarrollar cuellos más largos estirándose para alcanzar las hojas de los árboles de copas más altas y transmitían esta característica a su progenie, mientras que Darwin propuso que aquellas jirafas con cuellos más largos tenían más chances de sobrevivir que las que tenían cuello corto (selección natural), y las jirafas de cuello largo transmitían este rasgo a su descendencia (descendencia con modificación). Lamarck creía en la idea que las especies no poseen un antecesor común, mientras  que Darwin creía que todo el árbol de la vida está conectado a través de antepasados comunes. Finalmente, Lamarck pensaba que las especies no podían extinguirse, mientras que Darwin propuso la idea que las especies se extinguen y surgen otras nuevas a través de procesos de radiación adaptativa.

In the US, there are existing state laws to protect individuals from genetic discrimination in what areas? Select all that apply
bonufazy [111]

Answer:

In the United States there are existing state laws to protect people from genetic discrimination in areas such as insurance companies and workplaces.

Explanation:

Genetic discrimination is based on the possibility that an individual manifests a disability or inherited disease due to a genetic alteration.

In many cases, both workplaces and insurance companies require genetic testing before granting a job or an insurance policy.

A federal law - Genetic Information Nondiscrimination Act or GINA - protects people against this requirement of their future employers or any insurance company and guarantees, with certain exceptions, the possibility of obtaining a job or medical insurance.

In the case of the competitive inhibitor, we said that both k1 and KM are altered by that inhibitor. Since an uncompetitive inhi
umka21 [38]

Answer:

No changes occur to the K1 value, its concentration remains higher than the concentration of the inhibitor and enzyme inhibitor complex

Explanation:

Uncompetitive inhibition is an example of a reversible inhibition. Reversible inhibitors bind to enzymes by weak non-covalent bonding. Thus the formation and dissociation of this association is rapid. uncompetitve inhibition lowers the Vmax and Km.
