Domain System: What did Carl Woese use to determine links between organisms?

Biology

timama [110]2 years ago
7 0

Answer:

The Three Domain System, proposed by Woese and others, is an evolutionary model of phylogeny based on differences in the sequences of nucleotides in the cell's ribosomal RNAs (rRNA), as well as the cell's membrane lipid structure and its sensitivity to antibiotics. Comparing rRNA structure is especially useful.

The graph below compares the rates of reaction of a burning candle and an exploding firework.
marusya05 [52]

Answer:

The reaction that causes a firework to explode requires less energy to start, and occurs more rapidly than the reaction that causes a candle to burn.

Explanation:

The speed of a chemical reaction and the amount of energy required for this reaction is directly linked to the concentration of reagents present in the system. With that, we can say that the higher the concentration of reagents, the faster the chemical reaction will be due to the greater probability of collision between its molecules.

Although the reaction that causes a candle to burn has more reactants than the reaction that causes the fireworks to explode, the latter requires less energy to start. This makes the molecules of the reagents stir faster and collide more efficiently, making the reaction happen much faster.

In summary, the reaction that causes a firework to explode requires less energy to start and occurs more quickly than the reaction that causes a candle to burn.

If vascular plants have so many advantages, why do you think nonvascular plants still exist on earth today?
Verdich [7]
We all know that vascular plants really have many advantages. These refer to trees and flowering plants which really gives us what we need. While nonvascular plants are those small and simple plants which do not have any phloem or xylem. Despite nonvascular plants do not have as many advantages as the vascular plant to the people. They still played a big function in our ecosystem. For example, the algae, algae serve as the food of some of fishes in the pond or lakes. Non-vascular plants are also involved in processes like decomposition and indicators.<span>

How would over expression of protein phosphatase 1 affect the induction of cAMP-inducible genes in response to hormone stimulati
finlep [7]

Answer:

The protein phosphatase-1 dephosphorylates the residues of serine, which are phosphorylated by the protein kinase A. The cyclic-AMP inducible genes are stimulated by CREB that is phosphorylated by protein kinase A. Thus, overexpression of protein phosphatase 1 would prevent their induction.  

Although, protein phosphatase 1 would not influence the function of cAMP-gated ligand channels, as these channels are opened directly by binding of cAMP rather than by protein phosphorylation.
