Answer:
Phenotypic variation is the variation which appears in the phenotype or morphology of the organism. Natural selection is the mechanism of evolution in which the adapated organism to the environment is selected or highly favoured during the course of evolution.
A phenotype is the results of the genetic change which to be established in a population has to be passed on to the generation.
Since variation in phenotypic traits allows the organism to leave indifferent circumstances therefore phenotypic variation proves essential condition to natural selection.
Four abiotic factors in a prairie ecosystem would be soil, climate/temperature, water, and oxygen. Hope this helps!
Answer:
the SRY gene.
Explanation:
The SRY gene was found within the minimum region of Y-specific DNA required for male development. Confirmation of its role was found by the analysis of XY female patients with mutations within this gene. A mouse has been an important working model to study the process of mammalian sex determination.
Explanation:
in the diagram we don't know the value of X
but in the next figure we know how much the Forse is applied. so when describing a motion. we need to include the unit and the magnitude to underestimate there value
