Answer:
The correct answer is - humpback whales →sea turtles→humans→dolphins.
Explanation:
The hearing of sound is measured in hertz which is the unit of the sound that depends on the different frequencies of individual produce. The range of hearing sound is different in different animals.
Humpback whales produce sound between 30 to 8000 Hz however whales sense the vibration made by their song or sound by another whale. Sea turtles are able to hear in between the 20 to 1000 Hz whereas humans are able to hear 20 to 20000 Hz.
The highest hearing range of the sound is by dolphins from giving options as they are able to hear sound between 40 to 130000.
Thus, the correct answer is- humpback whales →sea turtles→humans→dolphins.
In a phylogenetic tree, close relations are usually shown by nodes branching off from the same line. The most recent evolutionary split would be at the end of the tree. Appearance doesn't necessarily reflect genetic closeness due to environmental influences and the development of analogous structures.
Without the specific phylogenetic tree to refer to, I can only explain the basis for the potential correctness of the statements provided. Typically, when analyzing a phylogenetic tree, close relations are typically indicated by nodes that branch off from the same line in the tree. As for the 'most recent evolutionary split', it would be the one furthest to the 'right' or end of the tree, being most recent time-wise. The level of similarity between organisms does not necessarily reflect their distance on the phylogenetic tree. Environmental adaption could allow two distinct species to appear more similarly than they genetically are. This is the concept of analogous structures.

Without the actual phylogenetic tree, it's challenging to provide a definitive answer to which statement is correct. The correct statement would be the one that represents the closest common ancestors between the species, as per the rules of phylogenetic analysis.
The question is about the analysis of a phylogenetic tree. Without the actual tree provided, it's challenging to provide a direct answer to which statement is correct. However, if we go by the rules of phylogenetic analysis, the correct statement would be the one that represents the nearest shared branches in the phylogenetic tree.
For instance, if the arctic fox and the fennec fox share a more recent common ancestor on the tree than the arctic fox and the kit fox, then the statement 'The arctic fox is more closely related to the fennec fox than to the kit fox' would be considered correct. The same logic applies to the other species mentioned in the other statements. Therefore, without the actual tree, we cannot definitively state which statement is correct.
Phylogenetics is a major part of evolutionary biology and it involves the study of the evolutionary relationship amongst various species. These relationships are discovered through phylogenetic inference methods that evaluate observed heritable traits, such as DNA sequences or morphology under a model of evolution.

B.A mouse evades detection by predators by lying very still.
C.A mouse forages for food close to its nest.
D.A mouse is active at night so that predators have a harder time seeing it.
