A phylogenetic tree,<span> or </span>evolutionary tree,<span> is a branching </span>diagram<span> or "</span>tree<span>" showing the inferred </span>evolutionary<span> relationships among various biological </span>species<span> or other entities </span>based upon similarities and differences in their physical or genetic characteristics. The taxa joined together in the tree are implied to have descended from a common ancestor<span>.</span><span />
It would be completely false to state that adult <span>brains have about five times the number of connections that a three-year-old has. The correct option among the two options that are given in the question is the second option. A child brain has twice as many connections than that of an adult brain. </span>
Identical daughter cells are produced as a result of mitosis whereas meiosis results in the formation of the daughter cells which are different genetically.
Mitosis and Meiosis are the stages of the cell cycle which can be further divided into stages called prophase, metaphase, anaphase and telophase. Mitosis results in the formation of two diploid daughter cells which genetically identical to the initial parent cell.
In the process of meiosis, the DNA gets exchanged between the chromosomes that are paired. This shuffling of DNA results in the formation of daughter cells after cell division which are genetically dissimilar.

Answer:
- <u>White-bark pine trees:</u>
The specie of plants are found in the most of the national parks of Canada. As they have a high significance in providing more options or ways for the organisms to live. Wildlife is greatly benefited by the presence and increase population of the white-bark pine.
Explanation:
- <u>Effects due to decreased level of White-bark pine trees:</u>
If the population of the white-bark tree is reduced to half, then it will directly effect the level of steep slopes causing destabilization inside it.Along with that, it will also influence and reduce the amount of snow melt by sustaining snow drifts. As decrease in the number of this specie of plant's number will decrease the normal cycle inside the environment, if the cycle is disturbed.Then it will be responsible for the imbalance inside the nature. While it may also cause some of the hazardous events inside the biosphere.
- <u>May cause the decrease in population of the wild life:</u>
There are many species which are benefited by the presence of white bark trees, if the number of white bark tress declines to half then the species present will suffer greatly inside the region. As the support for the species regarding there source of food and shelter will decrease and will bring an imbalance inside the nature.
- <u>Decrease level of vegetation in the region:</u>
Due, to the white bark trees in the area the soil is kept safe from erosion and it increase the supply of nutrients and water towards the plants. As it helps in keeping the soil together which also helps in decreasing the chances of land slides during heavy rainfall in the region.
Now, if the number of the white bark trees declines then it may cause land sliding in the region along with other hazardous events along with it.As the soil capacity to hold itself all together will decrease, causing less water and nutrients transport towards the plants and other beings.
