Answer:
The duplication of a cluster of four Hox genes is equally likely as the duplication of a single Hox gene.
Explanation:
This comes from the definition of the parsimony principle, which is the action of choosing the simplest scientific explanation fitting the given evidence, meaning that all other elements are equal when evaluating the hypothesis. In biology the best hypothesis is the one that requires the fewest evolutionary changes.
Since three independent duplications of an individual Hox gene is in evolutionary terms, more complex than a single duplication or a cluster, then that hypothesis would be the most parsimonious.
Answer:
The Natural Step Framework is a methodology for successful organisational planning. It is based on systems thinking,
recognizing that what happens in one part of a system affects every other part. We begin by understanding the broader system
within which problems occur and the principles governing success within that system These principles for success then
provide a practical set of design criteria that can be used to direct social, environmental and economic actions, developing
effective, durable solutions to the environmental, social and economic issues of the new century.

Answer:
Dependent Variable: Babies that use the formula
Independent Variable: Babies Without the formula

As the formula dose Increases, So does the weight of the babies (figurativly)
This is the Dependent variable because it depends on another factor
The Independent variable doesn't depend on the amount of formula taken because it doesn't use the formula, therefore it doesn't depend on anything, its Independent.
