Hello!
Generally, a warm front is associated with rain and warmth, since the water vapor condenses once it hits a cold area of air. Once that clashing area passes, usually one or two days, it turns into warm and sunny weather with few precipitation.
Hope this helps!
The red node represent a speciation event and the common ancestor of the species B and C i.e option 1 and 4 are the right answers.
Explanation:
Speciation is an event that leads to splitting in a lineage producing two or more species. The speciation would lead to different species as they no longer can interbreed and produce viable offspring.
The node shows that the two species originated from the same root but undergone speciation to be two different species.
The speciation takes place due to genetic drift, selective breeding and mutations in the population which lead to Natural selection.
In the given picture the root with trait one got modified into trait 4 and 5 via trait 3. This means that due to mutation the genes have changed and evolved for better functions and thus they survived via Natural Selection.
The figure represents diverge population as two new species are there and thus is Allopatric Speciation and have common ancestors.

<span>Genes located on different chromosomes are inherited independently of each other. This is the principle of independent assortment, which was observed by Mendel during a scientific experiment of cross breeding pea plants. This principle does not always apply when genes on a chromosome are very close or linked to each other.</span>
They are called Consumers I believe hope that helps ☺
