Which compound is a reusable, complex protein that speeds up chemical reactions?
Irina-Kira [14]
Hello there! 

The answer is enzymes. 
Enzymes are biological catalysts, which means they decrease the amount of activation energy needed to start a reaction, therefore speeding up the rate of the reaction. They are part of the protein macromolecule group. Without them, our bodies would not process things efficiently or fast enough for us to live.

Hope I helped. Have a nice day.

boyakko [2]

Answer:

homologous

Explanation:

<em>Since the front legs of a cat and the arms of a human share a bone structure that suggests a common lineage, these structures are said to be homologous.</em>

Homologous organs are organs that share some similarities in different organisms but whose function differ in these organisms.

The organs are structurally similar but functionally different. Homologous organs represent one of the evidences scientists use to support evolution.

The front legs of cats and the arms of humans are functionally different, even though their structure is based on the same five digit plan.

Fahrenholz's rule is supported when: comparison of phylogenies for host and parasite show a correlated pattern of evolution

<h3>What is Fahrenholz's rule ?</h3>

The close correspondence is observed between the taxonomy of parasites and their hosts and this has led to Fahrenholz's rule. This rule postulates that parasites and the hosts speciate in synchrony.

This leads to a prediction that phylogenetic trees of parasites and their hosts are topologically identical.

when the only events in the process of reciprocal natural selection in the host and parasite lineages were those of contemporaneous speciation in both the lineages then host and parasite phylogenies are fully congruent, hence supporting Fahrenholz'srule.
