Dwayne is making a cladogram using a diagonal line.
Where should he place the least primitive organism?
E
A
B
D
PLEASE HURRY I REALLY NEED HELP BEFORE MY TEST!!!
Answer:
the answer is e on the test
hope this helps
Dwayne is making a cladogram using a diagonal line. He should place the least primitive organism in E. The correct option is A.
What is a cladogram?Diagrams are called cladograms to show the relationships between various taxonomic groups known as "clades." Cladograms reconstruct the taxa's evolutionary history (phylogeny) by showing these relationships. Phylogeny and trees are other names for cladograms.
Using the term "cladogram" emphasizes to some biologists that the diagram represents a hypothesis about the true evolutionary history of a group, whereas "phylogenies" represent true evolutionary history.
A cladogram's root, clades, and nodes are its most important components. The root is the first ancestor shared by all groups that branched off from it.
Therefore, the correct option is A, E.

Explanation:
Brain cells, which depend on glucose for energy, use the glucose transporter GLUT3, which has a Km of 1.5mM. Liver cells, which store glucose (as glycogen) after a meal and release glucose between meals, use the glucose transporter GLUT2, which has a Km of 15mM. Calculate the rate (as a % of Vmax) of glucose uptake in brain cells and in liver cells at circulated glucose concentrations of 3mM (starvation), 5 mM (normal levels), and 7mM (after a carbohydrate-rich meal). Use this rearranged M-M equation.
Answer:
Explanation:
Given that:
The brain cell which uses glucose transporter GLUT3 Km = 1.5 mM
The liver cell which stores glucose GLUT2 Km = 15 mM
The objective is to calculate the rate (as % of Vmax) of glucose uptake in brain cells and liver cells under starvation conditions.
Using the M-M equation i.e Michaelis- Menten equation;
[tex]Rate = \dfrac{V_{max}* [S]}{[S]+K_m}[/tex]
By rearrangement
[tex]\dfrac{Rate}{V_{max}}= \dfrac{[S]}{[S]+K_m}[/tex]
where;
[tex]V_{max}[/tex] = maximum velocity of a reaction
Thus; the rate as a % of Vmax of glucose uptake in brain cells is calculated as:
[tex]\dfrac{Rate}{V_{max}}= \dfrac{[3 \ mM]}{[3 \ mM]+1.5 \ mM}[/tex]
[tex]\dfrac{Rate}{V_{max}}= \dfrac{3 \ mM}{4.5 \ mM}[/tex]
[tex]\dfrac{Rate}{V_{max}}=0.667[/tex]
[tex]\dfrac{Rate}{V_{max}}=66.7 \%[/tex]
the rate as a % of Vmax of glucose uptake in liver cells is calculated as:
[tex]\dfrac{Rate}{V_{max}}= \dfrac{[3 \ mM]}{[3 \ mM]+15 \ mM}[/tex]
[tex]\dfrac{Rate}{V_{max}}= \dfrac{3 \ mM}{18 \ mM}[/tex]
[tex]\dfrac{Rate}{V_{max}}=0.166[/tex]
[tex]\dfrac{Rate}{V_{max}}=17 \%[/tex]
Thus, the uptake is larger brain cells due to the fact that the brain cells GLUT3 have higher tendency to attract glucose.
