Answer: The correct option is c. Segmentation evolved more than once in different branches of the cladogram.
Phylogenetic studies help to identify and understand evolutionary relationship between different life forms. It uses a diagram called as Cladogram to represent the branching of the evolutionary relationships. In cladogram studies each branching point tells a fundamental character of the evolutionary significance. Cladogenesis separates the gene pool by splitting into two or more than two separate pools each of which gives rise to one or more new species. Segmentation implies repeated parts and many animals consist of such repeated parts. Therefore, segmentation appears more than once in different cladogram branches.

Answer:
The correct answer is- make a prediction
Explanation:
A hypothesis can be defined as an explanation of any observation which can be confirmed by experiments and prediction is the guess about the future result of any observation.
As here a biologist hypothesized that the sound produced by frog is mating calls than the next step of the biologist would be to make a prediction about response of that mating call by female frogs. This is called hypothesis prediction method.
Therefore the right answer is- biologist will make a prediction.
Sodium would lose an electron to become a positively charged ion.
Answer:
Salivary glands secrete salivary amylase, an enzyme that begins the breakdown of starch into glucose. Mucus moistens food and lubricates the esophagus. Bicarbonate ions in saliva neutralize the acids in foods
