Amino acids
Amino acids are the smaller building blocks that make up
proteins. There are more than fifty acids and each one of them is a little
different from the other. They are used in every cell of the body, specifically
to build proteins that the body needs in order to survive. Out of the over 50
amino acids in the body, only 20 are used to make the proteins, though. Nine of
which are called essential while the remaining 11 can be synthesized by an
adult body.

Explanation:
grass lands aren't very cold
forests aren't cold
the desert is hot
and tundra is super cold
It contains 4 key elements carbon, hydrogen, oxygen and Nitrogen. so your answer is nitrogen
At really high pressures, carbon dioxide does form a liquid phase. Anyway, dry ice is much, much colder because carbon dioxide freezes at a lower temperature:-79 degrees Celsius or -109 degrees Fahrenheit!
Answer:
A. They are all equally related to one another.
Explanation:
In scientific terms, the evolutionary history and relationships of organisms is called phylogeny. Phylogeny describes the relationship of one organism to others, such as which organisms it is thought to have evolved from, which species it is most closely related to, and so forth.
Phylogenetic relationships provide information on shared ancestry but not necessarily on how organisms are similar or different. Scientists use a tool called a phylogenetic tree to show the evolutionary pathways and connections among organisms. A phylogenetic tree is a diagram used to reflect evolutionary relationships among organisms or groups of organisms. Scientists consider phylogenetic trees to be a hypothesis of the evolutionary past since one cannot go back to confirm the proposed relationships. In other words, a “tree of life” can be constructed to illustrate when different organisms evolved and to show the relationships among different organisms.
