Question
5. MODEL: Other hypotheses for the tree of life present Archaea as the ancestors to all other organisms. Make a sketch of a phylogenetic tree that presents bacteria and eykarva as more closely related to each other than to archaea, and has archaea as the sister group to bacteria and eukarxa, Either hand-draw and take a photo or create a computer-generated sketch of your phylogenetic tree and paste in the space below.

Picture a tree with three main branches: one for Archaea, one for Bacteria, and one for Eukarya. Place Archaea as a sister group to the clade that includes both Bacteria and Eukarya, showcasing a more recent common ancestor between Bacteria and Eukarya. The Bacteria and Eukarya branches emerge from a shared point, highlighting their closer evolutionary relationship, while Archaea stands separately on its own branch, indicating its distinct lineage.
You can replicate this concept using various online tools or even good old-fashioned paper and pencil. If you're interested in creating a digital version, tools like "iTOL" (Interactive Tree Of Life) allow you to build and customize phylogenetic trees with ease. Just remember to save your masterpiece or snap a photo of your hand-drawn version for submission!

Both epinephrine (a tyrosine derivative) and glucagon (a peptide hormone) increase glucose export from the liver into the bloodstream.
Each ligand binds a different receptor, but both lead to an activation of PKA. How does this happen?
Choose one:
A. Each activated receptor interacts with a unique GTP binding protein that activates PKA.
B. Both receptors bind and activate the same Ga subunit, Gsa, which indirectly leads
to PKA activation.
C. Both receptors bind directly to and activate PKA after the Gsa protein dissociates
from the receptor.
D. The receptors for the two ligands interact before binding to the heterotrimeric G proteins.
