Answer:
The duplication of a cluster of four Hox genes is equally likely as the duplication of a single Hox gene.
Explanation:
This comes from the definition of the parsimony principle, which is the action of choosing the simplest scientific explanation fitting the given evidence, meaning that all other elements are equal when evaluating the hypothesis. In biology the best hypothesis is the one that requires the fewest evolutionary changes.
Since three independent duplications of an individual Hox gene is in evolutionary terms, more complex than a single duplication or a cluster, then that hypothesis would be the most parsimonious.
Answer:
true
Explanation:
Penicillin is a bacteria so it means it causes the production of antibodies which then boost the immune system.
It is like vaccination; small doses of the inactive form of the infection is injected into the body in order for the body to create antibodies resistant to such infection(thereby boosting the immune system).

Answer:
Assuming you mean in a compound of elements: A name is just what you call it, and the chemical formula is what elements it is made of.
Explanation:
Take sodium chloride (Salt) for example. It's name is sodium chloride, but its chemical formula is NaCl. Na= Sodium, and Cl = Chlorine. So one sodium ion and one Chlorine ion create NaCl. Na+Cl=NaCl. And the name for the product of the formula is Sodium Chloride.
Another example is H2O (Water). H=Hydrogen and O=Oxygen. There are 2 hydrogens and one oxygen in H2O. H+H+O=H2O. The name for the formula is water.
