Which pedigree symbol is used to represent a female carrier of a recessive X-linked trait? An empty circle. A half-filled circle
hodyreva [135]

Answer:

A half filled circle

Explanation:

In pedigrees, females are always denoted with a circle, and males with a square. Affected individuals usually have coloured or filled symbols, whereas unaffected individuals have an empty symbol.

In the case of carriers, this is often denoted as a half filled symbol. I.e. the shape is filled on one side and not the other, split down the middle). Sometimes a carrier of an <em>X linked</em> condition is denoted as a half filled, but instead of left vs right, the circle is filled with a smaller circle in the middle.

Porque un grupo de celulas pequeñas ayudarian a un organismo a mantener la homeostasis mejor que una celula grande?
NeX [460]

Answer:  

Una parte fundamental de la homeostasis es la transferencia y la ingesta de moléculas (sea necesario o no). Es importante que la célula pueda llevar los nutrientes necesarios inmediatamente donde los necesita y poder deshacerse de los subproductos dañinos del proceso celular. Es igualmente importante poder regular la concentración de agua. Las células más pequeñas tienen una superficie más grande en relación con su volumen (su superficie se escala con R ^ 2 mientras que su volumen con R ^ 3 donde R es el radio de una célula) y, por lo tanto, los intercambios a lo largo de la membrana celular se ven favorecidos en comparación con las células más grandes que necesitan muchos intercambios pero tienen proporcionalmente menos área de membranas. Si bien A no es necesariamente cierto, C es definitivamente cierto y, por lo tanto, la respuesta correcta.
