Which statement is correct based on analysis of this phylogenetic tree?. The arctic fox is more closely related to the fennec fox than to the kit fox. The Cape hunting dog is more closely related to the coyote than to the black-backed jackal. The most recent evolutionary split was of the fox from the coyote. The closest relative to the crab-eating fox is the gray fox.Which statement is correct based on analysis of this phylogenetic tree?
Answers
Final answer:
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.
Explanation:
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.

Final answer:
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.
Explanation:
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.

Co-evolution
Explanation:
The given statement implies that arthropods had more time to co-evolve with land plants than vertebrates
- Co-evolution is a type of evolution in which two species reciprocally affect each others evolution in a way that they both evolve together
- Fossil evidence gives the progressive interaction between arthropods and land plants through the later Paleozoic and Mesozoic era
- Evidence includes the evolution of chemical defense strategy by plants along with the evolution of different mouthpart design in new insect groups
- Leaf galls became common in Cretaceous coinciding with the evolution of several new insect groups and plants
- Data from coprolites(trace fossils) suggest that spore feeding preceded leaf feeding,experiments have indicated that some spores remain viable after passing through the gut and hence this feeding habit might have been advantageous to some early plants for propagule formation

They constitute the genetic material of living beings and act in the formation of proteins.
Explanation:
Both DNA and RNA are extremely important for life: they constitute the genetic material of all living beings. In the case of eukaryotic organisms, nucleic acids are present in the nuclei of cells, while in prokaryotic organisms (which have no nucleus surrounded by a membrane), the genetic material is dispersed in the cytoplasm. In addition, DNA and RNA are extremely important for the formation of proteins that will command all the functions of our body.

The skin is the answer. It is an organ of protection.
The skin is made up of two layers namely the epidermis and the dermis. Under the dermis is found hypodermis which is subcutaneous fatty tissue.
The skin has three major functions namely protection, regulation and sensation. When the skin is broken, i.e. wounded, all these functions are affected.
The skin acts as a barrier, providing protection from radiation from the sun, mechanical impacts, pressure and changes in temperature, as well as from microorganisms and chemicals.

Answer: option C) species -> community -> biosphereD
Explanation:
Species refers to closely related organisms (plant or animal). When different species of organisms live together in a habitat where they feed on one another and become codependent on one another, a COMMUNITY has been formed.
A BIOSPHERE, however is composed of many ecosystems i.e different species of plants, animals and microorganisms relating with their environment. Thus, a biosphere = Communities + environment
