Which of the following explains why cattle should not be given apples?
Nata [24]

Answer:

"Cows that eat apples can get a bloated stomach and die. But that's not what's happening when your cattle feed on apples fallen on the ground or those that you offer them to diversify their diet. ... So, if you plan to introduce apples into your cows' diet, do so gradually."

Can you tell from this tree whether a C at position 15 evolved before or after a T at position 15? Explain your answer
Ratling [72]

The evolutionary tree is not observed here but it is possible to answer this question by observing which nucleotide is found in the root of the node. It indicates the first substitution.

<h3>What is an evolutionary tree?</h3>

A phylogenetic evolutionary tree is a diagram used to show the evolution of a given taxonomic group (for example, a group of species).

It is possible to trace the evolution of a given taxon by tracing the nucleotide substitution observed from a common ancestor.

In an evolutionary tree, the root of the node is represented by the common ancestor and therefore the presence of a particular nucleotide (either T or C) in that position can be considered as the ancestral character.
