lara [203]3 years ago
7 0

Blood is made up of red and white blood cells, platelets and plasma. The plasma consists of water (mostly) and dissolved nutrients. When blood is exposed to air, the blood will clot, due to aggravation of the platelets. Then you get a  forming scab that will help heal the part that the blood is being exposed from.

Two competing hypotheses to account for the increase in the number of Hox genes from the last common ancestor of bilaterians to
Tomtit [17]

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.
