Secondary succession occurs when a natural devastating calamity or event takes place such as hurricane and forest fire. It is often faster compared to primary succession because there are available resources already including soil, roots, seeds and other vegetative organs from plants can be found underground.
Answer:
Potential targets:
1- DNA methyltransferases
2- Chromatin modifiers such as histone acetyltransferases, histone deacetylases, histone methyltransferases, etc.
3- Components of the RNA interference (RNAi) machinery such as Dicer, Argonaute, etc.
Explanation:
Epigenetics can be defined as the study of any heritable change in the phenotype that does not involve modifications in the DNA sequence. Epigenetic mechanisms can be classified into three major types: 1-DNA methylation, 2-histone modifications (e.g., acetylation, methylation, phosphorylation, etc), and 3-regulatory non-coding RNAs (e.g., miRNAs, lncRNAs, siRNAs, etc) that modulate target gene expression via the RNA interference pathway. There are different types of proteins that are involved in these complex epigenetic mechanisms, and those cited above represent only some examples that can be used as therapeutic targets.
Answer:
The glyptodon is found to be similar to the armadillo.
Explanation:
A piece of evidence that supports the theory of evolution is that the glyptodon is found to be similar to the armadillo. Glyptodons and armadillos have many things in common, expect that glyptodons are much larger (the size of a Volkswagen beetle!) than an armadillo. The change from the prehistoric glyptodon to our modern day armadillo helps support that there is evolution because they still have many things in common. They are genetically related.
Earth's rotation causes the Coriolis effect.
