Answer:
- Parents are heterozygous for the trait, and this is how they got a child with no freckles.

Explanation:
Due to technical problems, you will find the complete explanation in the attached file.
A: the molecules spread out and move more quickly
B: the temperature increases as the water molecules change from ice to vapor since it goes into the melting phase and then the condensation phase
Answer:
D) choose the tree that represents the fewest evolutionary changes, either in DNA sequences or morphology.
Explanation:
Parsimony is a concept applied while constructing a phylogenetic tree. According to it the best tree is constructed by fewest evolutionary changes, either in DNA sequence or morphology. Complicated changes should be present as less as possible in a tree.
For example, suppose vertebrate relationship can be explained using two trees. Tree A has six evolutionary changes and evolution of bony skeleton occurs once. Tree B has seven evolutionary changes and evolution of bony skeleton occurs twice at different spots. Tree A will be preferred because it explains the vertebrate relationship in a less complicated way than Tree B.
What system are we talking about? Context is needed... water cycle, cells, etc?
Answer:
The flanking residues facilitate recognition and specificity.
Explanation:
The kinase is able to to specifically phosphorylate serine and threonine due to the recognition of the flanking residues. Altogether, these form a consensus sequence across the substrate.
