Hey
Explanation:
Covalent bonds and ionic bonds are two different ways of how elements bond to each other. The main difference between covalent and ionic bonds is that ionic bonds occur between two species which are electrostatically attracted towards each other, whereas covalent bonds occur covalently through the sharing of electrons between their outer shells.

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.
If you can connect air pollution leads to global warming and thus climate change.
So in order to decrease pollution levels
1. Lessen the usage of vehicles (motorised)
2. Industrial waste should be treated properly before releasing into the atmosphere
A renewable resource is a resource that can be renewed/or replinished meaning the Sustainably Harvested seafood must be your answer. Natural gas takes too long to replenish so it is considered non-renewable. You can bring back sand once it's gone nor Methane Hydrates.
