Answer:
A) Traits can be dominant or recessive, and the recessive traits were "hidden" by the dominant ones in the F1.
Explanation:
Mendel discovered the fundamental theory of heredity: that inheritance involves the passing of genes (he called it discrete units of inheritance), from parents to offspring. Those genes are with two alleles in the genotype, one inherited from the father and other inherited from the mother.
When he cross-bred pure-bred parent (always produced offspring identical to the parent) plants dominant traits were always seen in the offspring, while recessive traits were hidden until the first-generation (F1) hybrid plants were left to self-pollinate. Mendel also noticed that in second-generation (F2) of the offspring 3:1 was ratio of dominant to recessive traits.
<span>Geologists generally know the age of a rock by determining the age of the group of rocks, or formation, that it is found in. The age of formations is marked on a geologic calendar known as the geologic time scale. Development of the geologic time scale and dating of formations and rocks relies upon two fundamentally different ways of telling time: relative and absolute.</span>
Answer:
The answer is Kastle-Meyer test..
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.
