If in an eight-cell embryo of an organism, the cells of the upper tier are aligned over the cells of the lower tier at a slight angle, it is likely that the organism is a vertebrate.

In the broadest sense of the term, we have modified the genes of almost everything. We used selective breeding to breed the most resistant form of crops, the largest sized chickens, and others. In recent years we have even modified them through gene splicing and other methods. Nearly everything we eat, including including "organic" foods have been changed from their original DNA structure, in fact we do not even know anything's original genetic structure because of this. Genetic modification could also include mutations. Some crops have mutated due to pollution, disease, or other effects such as climate change. Without genetic modification our world would differ from what it looks like today.
States enjoyed greater autonomy under the Articles, whereas the Constitution granted some powers to the states.
<h3>What is articles of confederation?</h3>
- The 13 founding states of the United States of America came to an agreement known as the Articles of Confederation and Perpetual Union, which functioned as the country's first system of governance.
- On November 15, 1777, the Second Continental Congress approved it following lengthy discussion and forwarded it to the states for ratification.
- In the Articles of Confederation, which served as the nation's first constitution, the confederacy of the former 13 colonies was referred to as "The United States of America."
- The 13 articles that made up the Articles of Confederation granted authority to a federal government headed by Congress.
- Following the United States' declaration of independence from Great Britain, the national government's functions were codified in the Articles of Confederation.
- The Continental Congress approved the Articles of Confederation on November 15, 1777.
- This text functioned as the first constitution of the United States.
- It lasted from March 1, 1781, until the current Constitution took effect in 1789.

Answer:
Attached R side groups
Explanation:
The proteins are one of the important biomolecules which are directly coded by the genetic material of an organism.
The proteins are composed of the amino acids which possess, an amine group, a carboxylic group and an attached side group called the R group.
It is the R group of an amino acid which determines whether the amino acid will a polar or a non-polar amino acid molecule thus it determines the properties of the amino acid in terms of chemical properties. The R side group are involved in the formation of bonds with the substrate of the environment and the tertiary structure of the proteins.
Thus, the presence of different R group is the key difference in 20 amino acids.
