Answer:

Parsimony

Explanation:

Parsimony or maximum parsimony is a simple criteria used to score a phylogenetic tree. This method minimizes the chances of homoplasy in an evolutionary tree.

Parsimony mainly based on the principle that the shortest number of character states changes and the total minimum number of character state changes is preferred in the evolutionary tree.

Thus, the correct answer is option (A).

Answer:

If these were the missing choices:

A) Positive, since it is needed for the local bird population.

B) Negative, since it is destroying much of their environment.

C) Positive, since it is a sustainable plan to use a renewable resource.

D) Negative, since it is a sustainable plan to use a renewable resource.

My answer would be: C) Positive, since it is a sustainable plan to use a renewable resource.

Renewable source is defined as resources that can be replenished overtime by natural processes. Farming trees is one of the processes that produces renewable sources.

A plasmid contains the gene for tetracycline resistance and a lacz gene that has a restriction site in it. Foreign dna has the s
tester [92]

Answer:

The colonies are carrying the resistance genes from plasmids

Explanation:

Bacteria can acquire beneficial characteristics that they didn’t have. One way for these is through plasmids, which ones are little fragments of DNA that usually contains resistance genes (for antibiotics, disinfectants, heavy metals, etc.) or other capacities, like the ability to use some substances (for example sugars).

In this specific situation, we already know that the plasmid carrying genes for tetracycline resistance and the <em>lacZ</em> gene.  

A little explanation:

Tetracycline is an antibiotic that inhibits bacterial growth and kills the bacteria.  The bacteria can “fight” to this antibiotic if it has a resistant gene, the result is that the antibiotic can’t affect the bacteria and survive.  An analogy is like a Police Officer (bacteria) that have a bulletproof vest (tetracycline-resistant gene) so the bullets (tetracycline) didn’t affect the police.

In the case of X-gal, is a compound consisting primarily in one sugar called galactose. Not all bacteria can eat galactose, they need an enzyme called β- galactosidase (comes from <em>lacZ</em> gene) that helps the bacteria “eat” the sugar (cuts the sugar in little pieces so the bacteria can eat).  

Then, as the bacterial colonies can grow in the medium with tetracycline and X-gal,  we know that those bacteria are carrying the resistance genes for tetracycline (does not affect the bacteria) and the <em>lacZ</em> gene (bacteria produce β- galactosidase that cuts galactose). These genes are coming from the plasmids because we already know that the plasmid carries these genes and not from the exogenous DNA.
