Yay Sachs disease is a disorder characterized by an accumulation of fatty substances called gangliosides in the brain and spinal

cord. One cause of the diseas is a mutation in the gene sequence that codes for the enzyme hexosaminidase A. The enzyme is rendered nonfunctional when a single amino acid is incorporated into the enzyme instead of an arginine. In this scenario, what is the cause of tay-Sachs disease

If all living things are related then where did all their differences come from?
stiks02 [169]

Answer:

<em>Hox </em>Gene

Explanation:

First, you're question is very vital, there are many ways in classifying along with identifying all living organisms that includes; morphological analysis, molecular systematics (studying the similarities and differences of the genetic data such in the sequences of DNA, RNA, and rRNA ), homology, cladistics, etc. based on phylogenetic tree, which the study of the evolutionary among various species.

But through it said that all living organisms shared one common ancestor. However, what makes them different from one to another is the homeotic genes that called <em>Hox </em>Genes; which specify the fate of a particular segment or region of the body, meaning the number and arrangements of the<em> Hox</em> genes varies considerably among different types of animals.

For instance, Sponges have at least one homologous to<em> Hox</em> genes, also insects have nine or more <em>Hox </em>genes resulting in multiple <em>Hox </em>genes occur in a cluster in which the genes are close to each other along a chromosome. Therefore, increases in the number of<em> Hox</em> genes have been instrumental in the evolution of many animals species with greater complexity in body structure.

Overall, more <em>Hox</em> genes, more complexity in body structure resulting in the differences of their morphological structure.

Hope that answered your question!

Explain why evolution is a unifying theme
Setler [38]
Unify means to make or become united uniform, or whole.

(I personally don't agree that evolution is true; but here is my answer)

Evolution is a way Scientists like to theorize the world was made/ created. They try to explain why everything can about in a uniform way. Everything has a reason or theory. Even though scientists haven't been able to prove that Evolution actually exists, many people like the idea of it- just for the reason that it gives a more believable whole approach to how the Earth and Universe came about. For some people, it is more uniform than a religion.

I hope this helped you!
