Due to convergent evolution placental mammals (Wolf) are closely related to marsupial wolves (Tasmanian wolf). No, the tree is wrong.
What is convergent evolution?
It is the presence of similar features in animals of different lineages. The structures in these animals have similar functions but are absent in the common ancestors hence they are analogous structures not homologous.
Such convergence of functional, morphological, and structural traits from phylogenetically unrelated species may be a result of random mutation due to selection pressure.
Here, the Tasmanian wolf (marsupial wolf) and wolf (placental mammal) have several morphological similarities but they have unrelated ancestral lineages. Hence they show convergent evolution. These two subclasses of mammals have adapted to a specific food source, locomotor ability, or environment in similar ways.
Hence, the placental wolf and Tasmanian wolf exist sharing the same habitat in different continents former in Asia and the latter in Australia because these two show convergent evolution.

Answer:
B. A change in the DNA sequence of a gene
Explanation:
First I would use a magnet to get the iron filings out then I would use a sieve to separate the wood chips from the sand and salt. After this pour water into the sand and salt and put it through filter paper, the salt will go through as it is dissolved in water and the sand will be left behind. Place this salt solution into a dish and put it over a flame, the water will evaporate and leave the salt behind
Answer:
A fishes brain as about as small as a picec of sand so they kind-of dumb
Explanation:
i love my fish tho
Hello. You forgot to add the diagram.
The diagram is attached below.
Answer:
1. examination of homologous fossilized structures of primitive horses
Explanation:
As you can see in the diagram, to show the stages of the development of the modern horse, a comparison is made between the forelimb structure and the molar tooth of these horses (related to the adult form). These two factors of comparison establish the representation of fossilized homologous structures of primitive horses.
As you may already know, homologous structures are different body structures from different animals that have a strong similarity (because they are inherited from a common ancestor). When these animals die and these structures are conserved, we can say that they have been fossilized.
As the forelimb structure and the molar tooth of the horses shown in the diagram are homologous structures that were fossilized, we can say that option 1 is the correct answer to your question.
