There are multiple lines of evidence that provide support for common ancestry and evolution. Write 3-4 paragraphs describing at
Colt1911 [192]

Though I cannot write this essay for you, I can provide some information to get you started on the relationship between ancestry and evolution.

<h3 /><h3>How are ancestry and evolution related?</h3>

Ancestry and evolution share a close relationship in that we can use one to learn about the other. Evolution can be <u>traced </u>using ancestry. By analyzing the genetic information of ancestral species and using information gathered about the environment in which they lived, we can deduce the impact of evolution on said species. One possible example is that penguins used to be capable of flight, but given their mostly aquatic environments, have evolved wings more suited for swimming, and lost the ability to fly as a result.

Therefore, we can say that ancestry and genetic information can be used to support the theory of evolution by examining how two species can be very different but share a common ancestor, and evolution can explain these changes.

Amyloidosis is caused by an abnormal deposition and accumulation of protein aggregates in tissues. How do proteins adopt and mai
Aleksandr [31]

Answer:

How do proteins adopt and maintain a stable folded structure? What features of the protein amino acid sequence determine the stability of the folded structure?

Proteins are formed by three-dimensional structures (twisted, folded or rolled over themselves) determined by the sequence of amino acids which are linked by peptide bonds. Among these bonds, what determines the most stable conformation of proteins is their tendency to maintain a native conformation, which are stabilized by chemical interactions such as: disulfide bonds, H bonds, ionic bonds and hydrophobic interactions.

How does disruption of that structure lead to protein deposition diseases such as amyloidosis, Alzheimer's disease, and Parkinson's disease?

The accumulation of poorly folded proteins can cause amyloid diseases, a group of several common diseases, including Alzheimer's disease and Parkinson's disease. As the human being ages, the balance of protein synthesis, folding and degradation is disturbed, which causes the accumulation of poorly folded proteins in aggregates, which can manifest itself in the nervous system and in peripheral tissues. The genes and protein products involved in these diseases are called amyloidogenic and all of these diseases have in common the expression of a protein outside its normal context. In all these diseases, protein aggregation can be caused by mere chance, by protein hyperphosphorylation, by mutations that make the protein unstable, or by an unregulated or pathological increase in the concentration of some of these proteins between cells. These imbalances in concentration can be caused by mutations of the amyloidogenic genes, changes in the amino acid sequence of the protein or by deficiencies in the proteasome.
