Distinguish between a dependent variable and an independent variable
Hatshy [7]

Independent Variables can be manipulated, and a Dependent Variable are observed and measured. Another way to say it is that the Independent variables change to get different results while the Dependent variables never change because you are trying to see what causes it to change

Which area of the graph shows the activation energy required if an enzyme was not present
boyakko [2]

B

Area B of the graph shows the activation energy required if an enzyme was not present

Explanation:

Reactions with high activation energy cannot occur spontaneously. Enzymes are responsible for lowering this activation energy and enabling reactions to occur at a faster pace than natural. An example is carbonic anhydrase enzyme that enables increased rates of carbon dioxide dissolving in and out of blood plasma.

Enzymes distort the bond of reactants such that they become unstable ( this raises the reactants Gibbs free energy). The bonds therefore break and rearrange to form the products of lower and stable energy states.

Describe maximum parsimony.
Burka [1]

Maximum Thrift is a method / philosophy that considers the shortest tree (in number of transformation steps) the best hypothesis about the phylogenetic relationship of a given set of terminals. Transformation step is the cost attributed to the change of character state in a given branch of the tree, be it the change from one nucleotide base to another, amino acids, or the color of an animal's iris. The fewer transformations, the shorter the tree, and therefore the more parsimonious.  In this method, what programs do is to investigate as many alternative topologies as possible (or all if their array has less than 25 terminals; see more details below) given their character array. Each will be measured, and the shorter (optimal) trees will be retained as the most parsimonious result.
