Becuase there is a broad range of phenotypes for human height, the trait is an example of a polygenetic (poly = many, genetic = of genes) trait.
Due to the vast variations of human height, the trait is clearly not purely dominant or recessive. A dominant trait is due to a dominant allele (variation of a gene) which completely masks a recessive allele. If only dominant and recessive height phenotypes existed, there would only be two heights observed in humans!
Since there is such a vast variation amongst human heights, the trait is an example of a polygenetic trait. Polygenetic traits are traits that are influenced by more than one gene at multiple loci (locations) on one or more chromosomes. This results in a continuous distribution of traits within a species. Other examples of polygenetic traits include skin color, hair color, and weight.
La respuesta es C. Aurícula derecha – ventrículo derecho y aurícula izquierda – ventrículo izquierdo.
Explicación:
El corazón, órgano encargado de bombear sangre, se divide en dos secciones principales, cada una con una función. La primera es la cavidad derecha también llamada el corazón derecho, esta estructura incluye el ventrículo derecho y la aurícula derecha; además, esta sección recibe sangre no oxigenada y la bombea hacia los pulmones. Lo que es necesario para oxigenar la sangre. La segunda cavidad es la izquierda o corazón izquierdo que incluye el ventrículo y la aurícula izquierda; además, esta sección del corazón difiere de la cavidad derecha porque distribuye la sangre al resto del cuerpo.
Answer:
Cell differentiation can be described as a process by which cells change into their specialized types. This process enables the cells to perform specialized tasks. The shape, size and even the metabolic activities of a cell might change after differentiation. All the cells of the body are derived from the stem cells which undergo cell differentiation to generate the specialized cells. The ability of a cell type to differentiate into other kinds of cells is termed as the cell potency.
Answer:
found the 100 point one.. but i agree with him so..
Explanation:
They disperse seeds via animals... I mean that animals like elephants eat the fruit of cycad and after when they go out through the faeces of animals, they are dispersed and hence grown!
It is important to carefully insert and remove the needle so the bacteria isn't spread throughout the medium.
